• Adjustable volume of alarms and notifications. |
StreetSiren DoubleDeck is a wireless outdoor siren with mount for the branded faceplate. Equipped with a LED frame and piezoelectric alarm indicator producing sound volume up to 113 dB, StreetSiren DoubleDeck Jeweller can operate up to 5 years from pre-installed batteries. It can also be powered from an external 12 V power supply.
StreetSiren DoubleDeck Jeweller communicates with the hub via two secure radio protocols. The siren uses Jeweller to transmit alarms or events and Wings to transmit photos and update firmware. The communication range is up to 1,500 meters provided there are no obstacles.
The siren is set up via Ajax apps for iOS, Android, macOS, and Windows. The system notifies users of all events with push notifications, SMS, and calls (if activated).
The Ajax security system can be connected to a central monitoring station (CMS) of the security company. A list of security companies is available on the website.
Operating principle
StreetSiren DoubleDeck Jeweller performs two tasks:
1. Informs about the alarm. The device responds to triggering of the tamper and security system alarms in less than a second, including a siren and LED backlight, which scares off intruders and attracts the attention of neighbors.
2. Serves as a security status indicator. The siren uses LED indication to notify that the object is armed, as well as uses sound and LEDs to notify about the delay when entering/leaving. These functions will be useful when controlling the security system using SpaceControl or KeyPad (the siren reminds you of disarming when you enter the object).
When installed properly, it is hard to dismount and disconnect an activated siren: its body is robust, the buzzer protected, and power is from the bundled batteries, so the siren will continue to work even if there is a power outage at the object. Also, if the system is armed, the power button is blocked, preventing the siren from being turned off.
The siren is equipped with a tamper button and an accelerometer. The tamper button is triggered when the device body is opened/broken, and the accelerometer is triggered when somebody’s attempting to move or dismantle the device.
Jeweller and Wings data transfer protocols
Jeweller and Wings are wireless data transfer protocols that provide fast and reliable two-way communication between the hub and devices. The siren uses Jeweller to transmit alarms and events and Wings to transmit photos and update the firmware.
Connecting a siren to a hub
The hub and the device operating at different radio frequencies are incompatible. The radio-frequency range of the device may vary by region. We recommend purchasing and using Ajax devices in the same region. You can check the range of operating radio frequencies with the technical support service.
