Wireless Interconnected Photoelectric Smoke Detector (Home Fire Alarm Device)

Ensure round-the-clock safety for your property with the Siterwell GS511E. Designed as a high-reliability HFAD, this smoke alarm uses advanced optical detection to identify slow-smouldering fires and dense smoke long before open flames erupt. With smart wireless interconnection and a sealed 10-year lithium battery, it provides complete multi-room protection with no battery changes required.   

Key Features

10-Year Sealed Lithium Battery: Powered by a built-in CR123A lithium battery providing a full decade of continuous, maintenance-free fire detection.

Advanced Photoelectric Sensor: Infrared optical technology detects toxic, smouldering smoke early without radioactive elements.

Wireless Interconnection: Radio-frequency linking connects up to 20–40 compatible units across an open-air range of over 100 metres - when one alarm triggers, every alarm sounds.

Powerful 85 dB Siren: Emits an 85 dB audible alert at 3 metres to alert sleeping occupants and ensure prompt evacuation.

Hush & Test Button: Integrated push button facilitates monthly functional tests and provides a 10-minute hush cycle for temporary cooking nuisance alarms.

Certified Quality: Rigorously tested and compliant with Australian Standard AS 3786:2014 (CSIRO approved).
