In less than one second, the AJAX StreetSiren DoubleDeck activates a powerful siren and bright LED indicators in response to an alarm signal. Any intrusion will thus be revealed immediately.

To indicate the status of the system

Thanks to the LED indication and the short beeps of the buzzer, users know that the building's alarm is enabled and that there is a delay in entering the function. This significantly reduces the risk of false alarms.

The right security for every location

The AJAX StreetSiren DoubleDeck has flexible settings that make it useful in both a quiet, secluded neighborhood and a noisy industrial park. The buzzer can be set to generate sound from 85 to 113 dB for an adjustable period of time: 3 to 180 seconds. Or it can also be completely silent if the device is set to respond to alarm signals only with an LED indicator. The Ajax app allows installers to choose detectors that activate the siren. This avoids awkward situations and saves your neighbors from having to be alerted every time the washing machine leaks.

Resistant to all weather conditions

The AJAX StreetSiren DoubleDeck can withstand heat, cold and rapid temperature changes. The hermetically sealed housing has an IP54 protection rating. The outdoor siren can withstand rain or snowfall, eliminating the need for a canopy on exterior walls.

Responds to alarms in a split second

We developed the Jeweller radio protocol so that we can guarantee uninterrupted operation of all devices within the security system. Jeweller uses time frames to synchronize the communications of connected devices, verification to eliminate forgery, and encryption to prevent data leaks. In addition, devices can operate for years with the pre-installed batteries. Thanks to Jeweller, the AJAX StreetSiren DoubleDeck responds to detector alarms within 0.3 seconds, even when the hub is offline.

Protected against vandals

An outdoor siren is best placed at a height of 2.5 meters. This improves visibility and audibility, and makes the device less accessible to intruders. If someone should still try to pull the siren off the wall, the accelerator will sound an alarm. In either case, the security company and users will be notified of sabotage and vandals will be deterred by the loud sound of the buzzer.
