## Summary description

Ajax HomeSiren is a wireless indoor siren in black with a maximum sound level of 105 dB. Designed to integrate with Ajax security systems, it provides audible alerts for intrusions and alarms. Suitable for homes and small businesses, it mounts indoors and operates without wires for flexible placement, improving on-site awareness and deterrence.

## Long description

Ajax HomeSiren Wireless is a compact indoor siren designed for integration with Ajax security systems. The device provides an adjustable audible alarm (81–105 dB at 1 m), an external LED connector for visual signaling and wireless connection to the Ajax Hub at distances up to 2,000 m in open space. It is powered by two pre-installed CR123A batteries and includes tamper protection and state indication (arm/disarm/armed).
Advantages
The siren supports long-range wireless communication up to 2,000 m in open space and maintains reliable connection across several floors. Sound level and alarm duration are configurable to match site requirements. Tamper-resistant housing triggers an alarm if the device is disassembled. Low standby current and up to 5 years of battery life reduce maintenance frequency. Installation does not require opening the body when using SmartBracket mounts, and connection quality can be checked remotely.
Suitable for
Homes and apartments
Small offices and retail spaces
Multi-floor buildings where long wireless range is needed
