| Part Number Breakdown: PG21-MS | |
|---|---|
| PG21 | Door Alarm (no bypass) |
| MS | Metallic Silver |
The Alarm Lock PG21 is a battery-operated door alarm that mounts directly on the push bar of any exit device. 100dB siren sounds immediately when the bar is pushed — no wiring, no panel, no electrician. Runs on a single 9V battery.
The PG21 is the basic model — every push triggers the siren, no bypass. For bypass capability, step up to the PG30.
Pro-Tip from Our Locksmiths: The PG21 is the no-frills alarm — every push triggers the siren. That's what you want on emergency-only exits where nobody should be going through during business hours.
