Sensaphone Magnetic Reed Switch Monitors Doors and Windows

Question about the Product: FGD-0006 Magnetic Reed Switch

Q: "I own several convenience stores that accept delivery at the rear of the store. I want to install these switches on the rear doors and on the front doors into each store so that my clerks know when the doors are opened. Is this switch normally closed? Or normally open? Does the magnet hold it open? Thanks, Basil"

Answer: Yes, this switch will meet your needs for monitoring doors. In combination with a Sensaphone system, you'd have all the monitoring capabilities you'd even need without paying for an alarm monitoring service.  The magnetic reed switch may be used with all Sensaphone models to detect any unauthorized entry or intrusion. They are usually installed on doors and windows to detect their opening and closing. Several magnetic reed switches may be wired in series.

My Sensaphone sales rep sent me this response. "The magnetic reed switch monitors the opening and closing of doors. So, this sensor can be configured as normally open or normally closed dependent upon whether the customer wants to monitor the door opening or closing."

From the spec sheet, I also gleaned the following.
Description: The magnetic reed switch may be used with all Sensaphone models to detect any unauthorized entry or intrusion. They are usually installed on doors and windows to detect their opening and closing. Several magnetic reed switches may be
wired in series.
