Question about advantages of Sensaphone Remote Monitoring Systems over security systems by national or local alarm and security companies.

Q: "We are building a new data center. Our choices are between a national or local alarm and security company with monthly monitoring fees or a Sensaphone system. We want to monitor power, temperature and humidity. We are also concerned about possible water leaks onto the flooring and being able to lower the thermostat in the room if one of the units begins to overheat. Which system do you recommend? Thanks. Bill."

Answer: For a data center, we would recommend the Sensaphone IMS-1000 Internet Remote Monitor, IMS-1002 or Sensaphone IMS-4000 PowerGate2 Outlet Switcher IMS-4302IMS-4000 unit over the Sensaphone Web600 Web-Monitor Alarm, No Land Line Needed. The WEB600 is a great starter solution with accessories like a battery back up, a temperature probe, a zone water detector and a humidity transmitter.  However, when you are talking a larger computer room or data center, you are talking about tens or hundreds of thousands of dollars of equipment that keep your business operational 24/7.

Sensaphone Systems offer these advantages:

• No Monthly Monitoring Fees: you buy the product and programs it to notify directly any employee or employees you choose without the cost of a central service that runs at least several hundred dollars annually.
• Real Sensor Values: Universal inputs read actual temperature values and more.
• Battery Backup: Either included or an inexpensive option.
• Maximum Flexibility: Notifications using custom voice phone calls, emails, faxes, text messages, SNMP traps, etc. Communication is via land phone lines, cell phones, Ethernet or satellite.
• Remote Access: You can program remotely whether a phone line product, a web-based products or a satellite product.
• No Dependencies: stand alone solutions mean you get direct communication without a central service, computer or server in the middle.
• Field Proven in Sensitive Applications: Proven reliability and validity in emergency response materials, military weapons systems, medicines, Homeland security, etc.
• Innovation: In-house engineering. Three US patents for unique technologies. Constantly working to make products more powerful and easier to use.
• Easy to Use: Simple, clear set up and maintenance. You don't have to be an electronics genius! Some products like the IMS series even automatically detect the sensor you've connected and configure it for you. The owners manuals are extensive and clear to follow. Telephone technical support is there, unlimited and toll free.
• Made in the USA:  Yes! Sensaphone is made in Pennsylvania. All engineering design, manufacturing, servicing, testing and support are here in the USA.

For your data center, Safe Home recommends you choose the IMS-1002 model and then choose from the 9 sensors listed:

• IMS-4860: Sensaphone Magnetic Reed Door Switch for IMS-1000,4000 monitors a door for unauthorized entry
• IMS-4861: Sensaphone IMS Passive Infrared Motion Sensor for monitoring unauthorized access into a data center
• IMS-4862: Sensaphone Smoke Detector for IMS 1000,4000. Smoke Detector functions independently from any primary fire alarm system.

If a sensor is disconnected, you will get an alert. Each sensor is continuously monitored by the IMS parent unit. Cat-5 jacks and cables make it easier to connect to remote sensors using existing structured cabling.

The data logging includes a time stamped collection of input values that can be viewed and graphed. Plus you will get a detailed event history of user logins, telephone calles, etc. It is possible to add video integration to have an image sent of the condition that tripped the alarm. This is web-based monitoring with a traditional phone line, too.

You can place the IMS-1000 or IMS-4000 into your server rack. There are no moving parts in the IMS-1000 series units: each is complately standalone with its own internal battery back up.

Please contact us if you have additional questions. Thank you for your questions.

Question about the Sensaphone IMS-1000 Remote Monitoring System.

Q: "I have a computer room I need to monitor for humidity, power and temperature. There is no land line in that room. Is the IMS-1000 system the best choice? What sensors will I need to add?  How does this unit mount? I have computer racks in the room. Thanks. Ed."

Answer: Sensaphone designed the IMS or Infrastructure Monitoring System for situations like yours where there is no land line available. It does require an ethernet network. And you can rack mount this monitor into your computer rack. Dimensions (H x W x D): 1.75" x 14" x 7"

The IMS-1000 series of products includes the following key features:

• Eight sensor inputs to monitor environmental conditions and/or alarm contacts from other computer equipment such as UPS systems.
• 10/100BASE-T Ethernet port.
• Internal battery backup for uninterrupted performance.
• Compact design allows rack-mount, wall-mount, or tabletop installation.
• Embedded web page to program and manage your IMS-1000 system.

Per Sensaphone's manual for the IMS-1000:

"The system is designed to be a comprehensive method of ensuring 100% up-time of your computer systems. By monitoring all aspects of your computer room, including environmental conditions and network equipment, the system will keep you informed of the status of your infrastructure. Monitored conditions can include temperature levels, humidity levels, line voltage, leak detection, server response, UPS systems, and more. The system allows the computer professional to be notified immediately of any detected problems. Notification can occur via voice telephone call, pager, e-mail, fax or snmp trap. An internal battery backup system insures that the unit will continue to run if main power fails."

Sensaphone does caution: "Caution: The IMS sensors are not TCP/IP devices and therefore should not be connected directly to any wiring infrastructure that is connected to network equipment such as a hub, router, or switch. Sensors use RJ-45 plugs and cables similar to thoseused with Ethernet devices".

Environmental Sensors Needed for Your Computer Room Include:

• Sensaphone Temperature Sensor 4810 for IMS-1000,4000 The temperature sensor connects to the IMS-1000 via an RJ-45 cable (e.g. CAT5 cable). The connection from the sensor to the IMS-1000 can utilize your existing network wiring infrastructure. For example, the sensor may be installed in another room or another floor. Connect the sensor to your structured wiring network via an RJ-45 jack. At the other end, connect a patch cable from your structured wiring patch panel directly to the IMS-1000 environment input.
• Sensaphone Humidity Sensor 4820 for IMS-1000,4000 The IMS-4820 Room Humidity Sensor operates between 32° to 122°F (0° to 50°C)and Humidity ranges of 0 to 100% RH. Accuracy is ± 5%. This unit also connects with RJ-45 cable (not included).

Question about which Sensaphone monitor will closely monitor commercial and medical freezers and refrigerators in our facility.

Q: "We need to monitor 8 different refrigerators and freezers where we keep medical supplies. Which Sensaphone units will meet our needs? Thanks. Sue."

Answer: With the limited information you gave, I will do my best to offer you choices to meet your needs.

Sensaphone has two low temperature sensor models

The FGD-0107 is a unique 2.8K Temperature Sensor with Glass Bead Vial. This unit ideal for cold storage temperature monitoring. The glass bead filled vial buffers any momentary fluctuations that may cause a preliminary alarm dial out, such as defrost cycles, opening of doors, and fans circulating air. The glass beads will slow the response time of the sensor allowing normal daily operations to occur without having an alarm initiated. This is a highly recommended sensor for every cold storage application.

The Temperature Range that can be monitored depends upon which Sensaphone controller unit is being used:

• 400, 800: -20° to 150°F (-30° to 65°C)
• 1400, 1800, 2800, WEB600: -109° to 115°F (-85° to 57°C)
• 2000: -125° to 124°F (-87° to 51°C)
• Express II: -85° to 200°F (-65° to 93°C)

The IMS-4814 Ultra Low Temperature Sensor is designed to connect to the Sensaphone IMS product line (i.e. the IMS-1000 and the IMS-4000) and monitor temperatures in refrigerators or freezers. The electrical connection between the sensor and IMS unit is made via the attached RJ-45 patch cable. The package contains the 1) Ultra Low Temperature Sensor (1) Attached 7’ Patch Cable and (1) Attached 12’ of cable with weatherproof probe. The sensor probe may be secured inside equipment using the included clamp or it may be hung using tie wraps. Do not install the black plastic enclosure inside of a refrigerator or freezer. It is available with an optional NIST temperature certification. (IMS-4814-NIST) The Ultra Low Temperature Sensor comes with an attached 7’ cable with an RJ-45 plug on the end and a weatherproof probe with 12’ of cable. If the sensor installation is close to the IMS unit, you can plug it directly into an IMS environmental input. If the cable is too short you can use the included RJ-45 adaptor and a longer patch cable to extend the length. For applications where the sensor may be far from the IMS unit, you may utilize your existing network wiring infrastructure. For example, the sensor may be installed in another room or another floor. Connect the sensor to your structured wiring network via an RJ-45 jack. At the other end, connect a patch cable from your structured wiring patch panel directly to the Host or Node environment input.

• Temp Range: -122° to 53°F (-86° to 12°C)
• Humidity: 5–90% RH
• Sensor type: Sealed thermistor probe
• Accuracy: ± 3°F
• Connector: 7’ Cable with RJ-45
• Housing: Black plastic
• Compatibility: IMS-4000, IMS-4000 Node, IMS-1000

So next you need to determine which IMS (Internet Monitoring System) unit you need to handle your monitoring issues. The Sensaphone IMS-1000 has 8 sensor inputs. Configuration is easy: all IMS Solution sensors are auto-configured when you plug them into the IMS-1000. The Ultra Low Temperature Sensor will identify itself as a 4-20mA transducer. On the Properties screen for this sensor you must select the sensor type: either Low Temperature (Deg F) or Low Temperature (Deg C). When a sensor is removed, or the connection is disrupted, the configuration data remains intact but the sensor will go into trouble status and generate a trouble alarm. When the sensor is plugged in again, or the connection is re-established,configuration data remains unchanged and the sensor returns to normal operating condition.

The Sensaphone IMS-4000 in combination with the IMS-4000 node can monitor up to 64 sensors.

Please look at our webpages and decide which features you need. There are cross references on the pages to most sensors and to the IMS-4000.

Thanks for your question.

Sincerely, Barbara

 

Question about the Temperature Guard VM-5003HT Remote Temperature and Humidity Monitor

Q: "How does the Temperature Guard Monitor temperature and humidity? Is it automatic or do I have to set the temperature and humidity? Is it hard to program? Thanks Bill

Answer: Within the unit are sensors for both temperature and humidity. The programming is not automatic: you do need a telephone line to initially program the upper and lower limits and another phone to call it. Everything is done via voice prompts. It is very easily programmed by following the voice instructions.

This remote environmental monitor, made in the USA, is truly inexpensive insurance against humidity and temperature damage. The VM-500-3HT combines the VM-300 which allows you to program upper and lower temperature limits with the ability to do the same with humdiity limits. Examples for Use: Florida second homes, computer rooms and green houses. The units has a 4 hour battery back-up enclosed within the unit and a one year manufacturer's warranty. Programmable temperature limits: 35° F to 125°. Humidity sensor measures within a sensing range of 0% and 90%RH. Programmable humidity limits:  0% to 99%:accuracy 5%. Remote dial-in access: check power, temperature, and humidity any time by entering your personal code.

Worls with answering machines: Connecting the Monitor to a Phone Line which has a fax or
answering machine connected to it. Program the monitor to answer after one more ring than the other device
on the line. This allows the other device to always answer first.
To call and access the monitor
1 Dial the phone number
2 Hang up one ring before the other device answers.
3 Wait no longer than 30 seconds, then dial the number again.
4 The monitor will answer.
Example: An answering or fax machine on the same line as the monitor
and is set to answer after 4 rings.
Program the monitor to answer after 5 rings.
To access the monitor, dial the number, let it ring three times, then
hang up. Wait 30 seconds and call again. After two rings, the monitor

Question about the Temperature Guard VM500-3 Remote Access Monitor

Q; "We live in northern Minnesota and spend part of the winter in Arizona. We'd like to know if our furnace fails to maintain the 62 degrees F temperature we've set. How complicated is it to install a Temperature Guard VM500-3? This has been an especially brutal winter. Our son would install it for us since we are now in Arizona. Thanks. Dave

Answer: Installation is really simple. What I have done is added a list of the most frequently asked questions about this product. Not only is your home monitored but also you can phone your home or business any time of day or night and get the current temperature and power status. All this and no monthly monitoring fees!  Recently, the more popular of the Temperature Guard products have been the Temperature Guard VM500-3-30 Remote Access Monitor with a 30 hour battery back-up and the Temperature Guard w/Humidity Sensor/ Dial Out Alerts, the VM-500-3HT

These are the Most Frequently Asked Questions/Instructions about the VM-500-3 Temperature and Power Monitors

Use with DSL, i.e. you do not have a land phone line in your home.
    If your home has DSL, you must use a DSL filter with your VM500-3. This filter is included with each unit.

Use on a Digital Business Phone System: All Temperature Guard products require an analog phone line.  Most digital phone system manufacturers offer digital to analog converters that you can use to connect a Temperature Guard to your digital phone system. Temperature Guard products can share an analog fax line

How to set up the Temperature Guard
1) Locate the Temperature Guard (TG) in the area where you want the temperature monitored
2) Plug in the phone line and power pack and then turn the Temperature Guard unit on.
3) Call the Temperature Guard from another phone, or cell phone.
4) Follow the spoken instructions and the manual to program at least the following items:
    The phone number(s) where you want the TG to call you in case of emergencies.
    The upper and lower temperature limits.
5) Hang up by pressing the "0" key until the TG says "Good-bye".
6) That's it. The TG is now monitoring your home or business!

What happens when the temperature goes out of programmed limits?
1) The TG begins to make emergency phone calls starting with the primary phone number.
2) If a person or answering machine answers the phone at the primary phone number, then the TG will say, "Warning the temperature is xx degrees.  Please enter you PIN number."  xx is the temperature in degrees F.  If an answering machine answers, the TG will wait until your greeting message is over, and then it will leave the "Warning..." message. 
3) The TG will wait for a valid PIN number.
4) If a valid PIN number is entered, then the TG will stop making emergency phone calls.
5) If a valid PIN number is not entered or an answering machine answers, then the TG will continue making emergency phone calls with the second programmed phone number.
6) Once all the programmed phone numbers have been called the TG will wait twenty minutes and begin making phone calls starting with the primary number.
7) Steps 1) through 6) are repeated until someone enters a valid PIN number or the temperature goes back to within limits.
8) If a new alarm condition occurs, steps 1 through 7 are repeated again.

Can a Temperature Guard and an answering machine share the same line?
Yes, most answering machines answer the phone on the 4th ring.  To have the answering machine answer the phone, program the Temperature Guard to answer the phone on the 5th ring.   To access the Temperature Guard, call your home and let the phone ring 3 times.  Hang up and wait 20 seconds.  Call your home again and on the 2nd ring the Temperature Guard will answer.

Storage Instructions: What do I need to do to store my unit when I am not going to use it for a long time?
Make sure you turn off your unit for storage.  When you are ready to use it again, plug it in a few days before you need it to allow the battery to fully charge.

Using a Temperature Guard after storage: Charge the battery prior to leaving your home or business. Allow several days to charge after plugging the unit into AC power.

Restting the Maximum and Minimum Temperature Limits: To reset all max and min values on your unit, press 9 at the main menu.  This option is NOT spoken.  Pressing 9 will set the max and min readings to the current temperature (and current relative humidity on models equipped with humidity sensing).

Note: after pressing 9 you will be immediately returned to the main menu.  Press 1 to hear the current status of temperature, humidity (if equipped) and power.  The temperature and humidity high and low readings will be the same.

I hope this information has helped. Installing a Temperature Guard is one of the least expensive home disaster prevention devices available.

Thank you for your question.

Sincerely,

Barbara

Question about home power monitors.

Q: "I winter in Arizona. My home in Oregon is in the country at the end of the power grid. I leave the furnace set at 55 degrees while I am gone those 4 months. My neighbor keeps an eye on the house. But a storm or fallen tree can knock out my power and leave his power still on. I don't want my pipes to freeze or my home damaged. What do you sell that can alert him and me that the power is out at my house?"

Answer: We currently sell two brands of remote monitors. Neither require paying a monthly monitoring service fee. These are the Sensaphone and the Microtechnologies brands.

The Sensaphone 400 , once known as the Sensaphone "cottage sitter", lets you program in 4 phone numbers, add additional sensors, control your thermostat remotely, and has a 24 hour battery backup using C cells. Two other units are less expensive choices that would to meet your needs are the Homeguard and the TemperatureGuard monitors. What you are looking for is a monitor that can dial out an alert that the power is off and give you the temperature in your house as well.

The standard Homeguard and TemperatureGuard units have a built-in 4 hour battery back-up that activates when the power goes out. We've learned over the years that getting the insurance of  one with a 30 hour battery back-up has its advantages, primarily that the units will have extended battery so that if you turn off your phone at night (or your neighbor does), there will be enough battery left to continue dialing out until you wake up or turn on your phone or phones.

The Homeguard can dial up to 4 phone numbers. It also comes with a 30 hour battery back-up . The Homeguard alert is set at below 45 degrees F or power off for 5 minutes or more. The TemperatureGuard can also send messages to pagers as well as dial up to 4 phone numbers. The TemperatureGuard lets you choose both an upper and a lower limit (for summer and for winter) as well. Of course you can call into either unit at any time to get the power status (on or off) and the temperature. Both units and their brothers and sisters need a land phone line and electricity to work. Programming is easily done with a telephone.

Please read the instruction manuals on our website for more information or contact us.

Thanks for your question.

Sincerely,
Barbara

Q: "Is there a way to program the Home Guard Monitor 500-2 With 30 Hour Battery Backup NOT to call unless the power has been out for 6-8 hours?? The power frequently goes out for short periods of time around us and the 5 minute set up would be quite bothersome. The instructions explain how to set the temperature but not the time frame." Rick

Answer: We contacted the manufacturer for guidance. Here is the response from Microtechnologies: "I do not recommend setting the power outage time delay to 7-8 hours. How about starting with 1 hour and working your way up? Do you have the instructions for adjusting the factory default? If you do it is Option 6."

We hope this helped you. If not, please send us more questions.

Sincerely, Barbara
