Alarm Lock Systems Key-Activated Door Alarm PG21MS, Metallic Silver

When a door should stay closed unless someone with a key says otherwise, the Alarm Lock Systems PG21MS puts a local alarm right on it. Open the door without authorization and the unit sounds its alarm and lights its LED, so the breach is heard and seen at the opening. It mounts on standard size doors as well as narrow stile doors, and the metallic silver finish keeps it tidy on the frame.

You control it with a key in a standard mortise cylinder, or fit an optional rim cylinder instead. Two arming modes are selectable. In the standard mode you turn the key counterclockwise to disarm and clockwise to arm, and the key comes out in either position. In the always armed mode the key stays captive while the unit is disarmed and can only be removed once you turn it back to arm, so nobody walks away leaving the door unprotected. A red LED shows when the alarm is armed.

You also choose how the alarm behaves: continuous alarm, a minute shutdown with automatic reset, or exit/entry delay, with entry delay times of 15 seconds, 1 minute 15 seconds or 3 minutes 15 seconds. The tamper switch is supervised. Max-Flex terminals let you add an external power supply for continuous power and connect external reed switches to monitor more than one door. If you want a visual signal as well, the PG21MSS strobe version adds an amber strobe that flashes in alarm.
