Acts as an extension speaker in wired alarm systems, augmenting the audio coverage of entry, exit, and alarm tones. 

Doubles as an internal siren when the alarm is triggered, providing audible deterrence within the premises. 

The tamper detection adds a level of security by triggering an alert if the enclosure is opened or manipulated.

Design & Installation Notes

The compact, square form (110 × 110 × 55 mm) allows flush or corner mounting inside premises. 

Use wiring compatible with 16 Ω loads, ensuring the speaker is used within system limits.

When integrating with existing alarm systems, verify the total load (impedance and wattage) doesn’t exceed the panel or siren output capacity.

The tamper switches require connection to the system’s tamper loop or zone to trigger alerts properly.
