Alarm Lock’s PG21MS Series Door Alarms Advanced & Multi-Purpose
Amityville, NY – Alarm Lock’s multi-purpose PG21MS Series offers advanced narrow stile microprocessor-controlled door alarms for surface mounting on a door or doorframe. Typical applications include emergency fire escape doors, nursing home stairwell doors, rear restaurant and theater doors. The series work in two arming modes. Always Armed Mode causes the key to stay in place unless you turn the system back to arm from the disarm mode, keeping the unit armed always. Standard Arming Mode allows the user to disarm the system and remove the key. Turning the key clockwise will once more arm the system, with the option of taking your key out.

Features include a continuous alarm or 2-minute shutdown with auto reset and exit/entry delay status indicator LED light that becomes red when the system is armed. For entry, PG21MS has delay time options to include 15 seconds, 1 minute, 15 seconds and 3 minutes 15 seconds. Unauthorized use of the door causes the alarm to sound and the LED indicator to activate.

Multi-door monitoring is permitted with our built-in external reed switches. These versatile door alarms use a standard mortise cylinder and an optional RIM cylinder may be used for exterior key control. They come with a supervised tamper switch and Max-Flex Terminals, allowing for continuous power with the addition of an external power supply. The sleek design works on standard size and narrow stile doors and comes in metallic silver or duronodic finish. If you wish to include a highly visible amber strobe, you can do so with PG21MSS/PG21MBS. These units will flash when the unit goes into alarm mode.
