Ajax StreetSiren Black Wireless Outdoor Alarm Siren

Ajax StreetSiren Black Wireless Outdoor Alarm Siren

The Ajax StreetSiren is a wireless, battery-powered indoor/outdoor siren designed to give any Ajax security system a loud, visible response to intrusions, tampering, fire, or other alarm events. Built around Ajax's proprietary Jeweller radio protocol, it pairs quickly with an Ajax hub and communicates status changes, delays, and alarms through a combination of adjustable sound and a bright LED frame, making it a practical deterrent for homes, shops, offices, and warehouses.

Key Features

• Adjustable alarm volume from 85 to 113 dB, configurable directly in the Ajax app
• Flexible alarm duration, adjustable from as little as 3 seconds up to 3 minutes
• Silent LED-only mode so the siren can indicate alarms visually without sounding an audible signal
• Weatherproof IP54-rated enclosure resistant to dust, rain, and snow, suitable for exterior wall mounting
• Wireless Jeweller connectivity with a communication range of up to roughly 2,000 metres in open areas
• Long-life pre-installed batteries rated for approximately 5 years of use, with low-battery alerts sent to the app
• Tamper and dismount protection via an accelerometer and case-opening sensor that trigger an alarm if someone attempts to remove or open the unit
• Optional 12V DC external power input for sites where mains backup power is preferred
• Selectable trigger sources, letting installers choose which detectors or groups activate the siren to avoid false alerts

Reliable Outdoor Protection for Any Property

Because it ships with batteries pre-installed and mounts on the included SmartBracket, the StreetSiren can be fitted to an exterior wall or eave in minutes without opening the unit. It is well suited to residential properties, retail premises, warehouses, and offices where a clearly audible and visible warning is needed to alert neighbours, staff, or passers-by and to discourage an intruder from remaining on site. The black finish blends with darker building facades and fixtures.
