Ajax StreetSiren DoubleDeck: powerful alarm with a face of its own
The wireless outdoor siren from Ajax with an interchangeable front plate: the same powerful protection as the StreetSiren, but with a front that displays your own logo or ours.
The StreetSiren DoubleDeck responds to an alarm within 0.3 seconds, 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. The clip-on BrandPlate is included in the box as standard: you simply clip it onto the front and secure it further with a screw if you wish. The hermetically sealed IP54 housing can withstand rain and snow.
Why the StreetSiren DoubleDeck
Loud up to 113 dB
Adjustable from 85 to 113 dB at 1 metre, or fully silent with LED indication only.
Visible alarm
Next to the siren, an LED flashes, so the alarm is also visible and an intruder knows they have been seen.
Interchangeable BrandPlate
You simply clip the front plate on. Put your own logo or ours on it, so that the siren shows who is protecting the premises.
Responds in 0.3 seconds
Via the Jeweller protocol, the siren sounds within 0.3 seconds, even if the hub is offline.
Made for outdoor use
Hermetically sealed housing with IP54, works from -25 to +60 °C without additional covering.
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 siren on the façade or wall using the supplied SmartBracket, and use the supplied screws and wall plugs for a fixed mounting. The batteries are already installed, so you do not need to open anything: scan the QR code and pair it with your hub in the Ajax app. Clip the BrandPlate onto the front using the clip, and secure it further with a screw if you wish. In the app you set which detectors trigger the siren, the volume and the alarm duration. Do you want continuous power and status indication? Then connect it to a 12 V adapter (6 to 20 V); the batteries then serve as a back-up.

Frequently asked questions about the StreetSiren DoubleDeck
What is the BrandPlate and is it included?
The BrandPlate is the interchangeable front plate of the siren. It is included in the box as standard and you clip it onto the front with a small clip. You can have your own logo or ours put on it. The separate front plate is also available individually.
What is the difference from the standard StreetSiren?
The main difference is the interchangeable BrandPlate: on the DoubleDeck you put your own logo or ours on the front. In terms of sound, LED, IP54 protection and battery life, both sirens are comparable.
Can the siren be mounted outdoors without a canopy?
Yes. The enclosure is hermetically sealed to IP54 and operates from -25 to +60 °C. A separate canopy is not needed.
Does the siren also work if the hub fails?
Yes. Thanks to the Jeweller protocol, the siren responds within 0.3 seconds to a detector alarm, even if the hub is offline at that moment.
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.
