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. Opening 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 (allowing 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 select-able annunciator feature beeps to signal the opening of the door while the unit is disarmed.
