staple in all applications, from retail, to firms, to institutions and schools. And 

now the best, just got better! The New & Improved PG21 MS Series Door Alarms

than ever.

AppliCATioN:

The PG21MS is a magnetic contact controlled door alarm for surface mounting on 

a door or door frame. Typical applications include emergency fire escape doors, 

nursing home stairwell doors, rear restaurant and theater doors. PG21MS is de-

signed to continually monitor the status of a door. When opened, the protected 

door triggers an alarm sounder, an optional strobe or can activate another device 

via a Form-C relay. 

iNSTAllATioN:

The PG21MS unit is usually mounted on the interior of the door frame or door and 

is paired with a magnet mounted on the opposing side of the door gap. Open-

ing  the  door,  when  armed,  will  trip  the  internal  relay  thus  activating  the  alarm. 

Shipped in Always Armed mode can be converted to a manual On/Off mode (al-

lowing the operator to manually arm or disarm with the key). The Status indicator 

(located on the front of the Housing Cover) signifies whether the unit is armed or 

disarmed (red indicates armed status). A selectable annunciator feature beeps to 

signal the opening of the door while the unit is disarmed.
