Ajax Superior HomeSiren G3 Jeweller Black — Wireless Grade 3 Indoor Siren

Wireless Grade 3 Indoor Siren with Sound/LED Alert and Jamming Detection Ajax Superior HomeSiren G3 Jeweller Black

The Ajax Superior HomeSiren G3 Jeweller in black 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.
