The Ajax HomeSiren Black for indoor acoustic alert and perimeter deterrence

The Ajax HomeSiren Black represents a crucial pillar in active deterrence for electronic security setups. This compact device emits a powerful acoustic alert during security breaches. Its integrated piezoelectric transducer performs with high efficiency. Its premium matte black finish ensures a discrete architectural integration. It minimizes aesthetic impact on dark ceilings and walls. It also avoids complex, costly hardware wiring layouts completely.

Adjustable volume level and real-time alert customization via mobile application

The acoustic alert system adapts perfectly to various indoor layout dimensions. Users can adjust the sound volume directly inside the official app. Available power settings range from 81 to 105 decibels. The reference distance is calculated at one meter. The acoustic signal duration is also customizable by software. It can be defined between 3 and 180 seconds per event. Additionally, the siren chirps during arming cycles. It displays system trouble indicators visually.

External status LED connector and stable Jeweller radio standard

The hardware features a built-in terminal block for practical field extensions. It allows connecting an external status LED indicator outside the door. This architecture expands visual control outside the secured premises. Integration within the layout uses the proprietary Jeweller radio protocol. It operates with permanent two-way AES block encryption from factory. It utilizes the stable 868.0 to 868.6 MHz frequency bands. It guarantees stable data transmissions up to 2000 meters in open field.

Mechanical anti-sabotage tamper and exceptional power management
