The Ajax Superior HomeSiren G3 Jeweller in white is the world's first wireless indoor siren certified to the stringent EN 50131 Grade 3 security standard, specifically designed for high-risk commercial and residential premises demanding ultimate sabotage resistance.
Featuring a high-performance piezoelectric sounder producing up to 105 dB alongside a bright LED frame, the HomeSiren G3 serves five vital missions: sounding loud intrusion alarms, indicating arming/disarming status, signaling entry/exit delays, alerting on door openings (Chime), and displaying after-alarm LED indication to notify owners if an alarm occurred in their absence.
The core breakthrough of the G3 series and the Superior Jeweller protocol lies in Grade 3 sabotage defense: the siren directly detects radio interference and jamming attempts, deploying advanced frequency hopping. It also includes a dedicated connector for an external LED.
#### Grade 3 Sabotage Protection & Battery Life
Mounted on the SmartBracket panel and locked with a dedicated holding screw, the siren triggers instant tamper alerts if unmounted or opened. The power button is automatically blocked whenever the system is armed.
Operating over two-way encrypted radio at distances up to 3,500 meters (11,450 ft) in open space, the device delivers up to 4 years of reliable operation on pre-installed batteries.
