Wireless street siren Ajax StreetSiren white IP54

Ajax StreetSiren white IP54 is a wireless outdoor siren that provides combined audio and visual alarm signaling for integration with Ajax Hub security systems. The device is weather‑resistant (IP54) and intended for mounting on façades, fences or other outdoor locations to warn of intrusion, fire or other emergencies. It supports wireless connection to the Ajax Hub up to 2,000 meters in open space and can be powered by an external 12 V DC supply or by built‑in batteries.

Advantages

The siren offers an adjustable sound level from 85 to 113 dB and a red LED light alarm. Tamper and dismount protection activate an alarm on interference. It supports long battery life (up to 5 years under normal polling intervals) and indicates battery level and current arm/disarm state. The device operates across a wide temperature range and high humidity and allows remote testing of connection quality and detection area. Installation is simplified by a SmartBracket mounting system and an interactive manual.

Suitable for

• Outdoor perimeter protection of residential or commercial properties
• Mounting on façades, gates or fences to provide visible and audible alerts
• Integration with Ajax Hub for intrusion or emergency notification

How to use

Mount the siren on a flat surface such as a façade, fence post or gate using the SmartBracket mounting plate without disassembling the body. Connect an external 12 V DC power source if continuous mains power is required, or use the preinstalled 4 CR123A batteries for autonomous operation. Add the device to the Ajax Hub using the system’s pairing procedure and configure polling interval, alarm duration and sound level in the Ajax app. Test the connection and coverage remotely to ensure reliable operation.

Recommendations

Install the siren at a visible height and orient the sound output away from living spaces to reduce nuisance. Use the external 12 V DC supply for locations with frequent alarms or where long-term continuous operation is required; otherwise rely on batteries and monitor battery level through the Hub app. Verify signal strength and alarm area after installation to ensure coverage from the Ajax Hub.
