Ajax StreetSiren (Black) – Outdoor Wireless Siren

The best way to stop a burglary is to draw maximum attention. The Ajax StreetSiren is a heavy-duty, wireless outdoor siren complete with an LED strobe. Its deafening noise level drives intruders away before they even breach your property. The sleek black design adds a visual deterrent while seamlessly blending into modern, dark-colored exteriors.

Deafening Alarm and Strobe Ring

When the security system is triggered, the siren emits a piercing sound that can be adjusted from 85 up to a staggering 113 dB. This is paired with a bright red LED ring flashing rapidly around the circumference of the device. Via the Ajax app, you can easily customize the alarm duration (from 3 to 180 seconds) and set up subtle beeps to confirm when the system is armed or disarmed.

Weatherproof and Tamper-Resistant

Built for the outdoors, the StreetSiren boasts an IP54 rating, making it fully resistant to dust and driving rain. It is also highly tamper-resistant: a built-in accelerometer instantly triggers the alarm if someone tries to tear it off the wall. It operates wirelessly on 4 pre-installed CR123A batteries (lasting up to 5 years), but also features terminals for an optional 12 V DC hardwired power supply.
