Ajax StreetSiren: light and sound that drives off a burglar
A wireless siren for indoors and outdoors that signals with a loud tone and a clearly visible LED that something is wrong. The whole neighbourhood hears and sees the alarm, and an intruder knows immediately that he has been seen.
The StreetSiren is mounted on the façade or indoors on the wall and responds within 0.3 seconds to an alarm, even if the hub is briefly offline. You set the volume from 85 to 113 dB and the alarm duration from 3 seconds to 3 minutes, all in the Ajax app. The housing is hermetically sealed to IP54, so rain and dust do not affect it and a canopy is not needed.
Why the StreetSiren
Loud up to 113 dB
Adjustable from 85 to 113 dB at 1 metre, so you can match the volume to the surroundings.
Sound and light
Next to the siren, a clearly visible LED flashes, so the alarm can also be seen. If required, you can set it to respond silently with the LED only.
Responds in 0.3 seconds
Via the Jeweller protocol, the siren sounds within 0.3 seconds, even if the hub is offline at that moment.
Made for outdoor use
Hermetically sealed housing with IP54, works from -25 to +60 °C without additional covering.
Tamper protection
A built-in accelerometer raises the alarm as soon as someone tries to pry the siren off.
Batteries or 12 V
Runs on the four pre-installed CR123A batteries. How long they last depends on how often and how loudly the siren sounds. Do you never want to replace batteries? Connect it to 12 V.

Mounted in a few minutes
Mount the StreetSiren with the supplied SmartBracket on the façade or indoors on the wall, in a place where it can be clearly heard and seen. Use the supplied screws and wall plugs for a secure fixing. The batteries are already installed, so you do not need to open the siren: scan the QR code, pair it with your hub in the Ajax app and set the volume and alarm duration. Would you like continuous power and status indication? Then connect the siren to a 12 V adapter (6 to 20 V); the batteries then serve as a backup.

Frequently asked questions about the StreetSiren
Can the StreetSiren be mounted outdoors without a canopy?
Yes. The housing is hermetically sealed to IP54 and resistant to rain, snow and temperatures from -25 to +60 °C. A separate canopy is not needed.
How loud is the siren?
You set the volume from 85 to 113 dB at 1 metre. You can also mute it and have it respond with the LED only.
Does the siren also work if the hub fails?
Yes. Thanks to the Jeweller protocol, the StreetSiren responds within 0.3 seconds to a detector alarm, even if the hub is offline at that moment.
What happens if someone tries to break off the siren?
The built-in accelerometer raises the alarm as soon as the siren is moved or pried off, so tampering is reported immediately.
How long do the batteries last?
Ajax states up to five years, but that applies to minimal use. A siren draws a lot of current when it sounds, so the more often and the louder the alarm sounds, the shorter the batteries last. The Ajax app gives ample warning when replacement is needed. Do you never want to change batteries? Connect the siren to a 12 V adapter (6 to 20 V); the batteries then serve as a back-up.
