HONPSA2012-24AUSI 12-24VDC Photoelectric Smoke Alarm with Battery Backup

The HONPSA2012-24AUSI is a compact, low-profile 4-wire photoelectric smoke alarm designed to deliver early warning detection of developing fires in residential and commercial environments. Operating on 12–24VDC with a 9VDC carbon-zinc backup battery, it features an integral temporal-3 (ISO 8201) sounder outputting 85dB at 3 meters, NO/NC alarm relay contacts, and an 8-second alarm verification to reduce false triggers. Certified to AS3786:2014 and CSIRO ActivFire listed, it offers both visual and audible fault/battery warnings and supports interconnection of up to 24 units for large-scale protection.

The easy-clean sensing chamber, “HUSH”/test push-button, and dual-color LED status indicators simplify maintenance and operation. Its robust design ensures stable performance across a broad range of fire conditions, with suitability for integration into security or access control systems.
