StreetSiren DoubleDeck

Wireless outdoor siren with a clip lock for a branded faceplate


Reacts to alarms in a split second

We have developed the Jeweller radio protocol to ensure the uninterrupted operation of all devices within the security system. The Jeweller uses time frames to synchronize communication of connected devices, authentication to eliminate forgery, and encryption to protect against data leaks. Moreover, it allows devices to operate for years from pre-installed batteries. Thanks to Jeweller, StreetSiren DoubleDeck can respond to detector alarms in 0.3 seconds, even when hub is offline.

  • Two-way communication at a distance of up to 1,500meters,
  • Siren activation triggered by alarm in 0.3second, and
  • Adjustable ping interval from 12seconds.


StreetSiren DoubleDeck is resistant to heat, cold, and rapid changes in temperature. Its hermetically sealed body has been rated IP54 level of ingress protection. The outdoor siren is ready to withstand exposure to rains or snowfalls and can be installed on the exterior walls without a canopy.

  • Withstands heat up to +50°С,
  • Withstands cold up to −25°С, and
  • Protected from dust and precipitation IP54.

To attract attention

StreetSiren DoubleDeck needs less than a second to activate a powerful siren and bright LED indicators in response to an alarm signal. Any break-in will be immediately exposed.

To indicate the system state

LED indication and short beeps of the buzzer remind users that premises are armed and delay when entering feature is active. The risk of a false alarm becomes significantly lower.

Right protection for every setting

StreetSiren DoubleDeck is flexible when it comes to settings which makes it as relevant in a quiet gated community as in a loud industrial area. The buzzer can be set to generate sound from 85 to 113 dB for an adjustable period: 3 to 180 seconds. Or it can be completely silent when the device is set to respond to alarm triggerings only with LED indication. The Ajax app allows engineers to choose detectors that activate the siren. It helps to prevent awkward situations when neighbors are notified every time that a washing machine leaks.

Protected from vandals

2.5 meters is an optimal height for installing an outdoor siren. It improves visibility, audibility, and makes the device less accessible to intruders. Still, if someone will try to tear the siren off, the accelerator will trigger an alarm. In any case, alarm monitoring company and users will be notified about sabotage, and vandals will be deterred by a loud sound of the buzzer.

Effortless maintenance

Outdoor siren operates for 5 years on the pre-installed batteries and features external power terminals. Whether to use batteries as a primary power supply or a backup one is your choice. In any case, the system will notify you about the need for maintenance when the battery level will drain to 20%.
