Ajax StreetSiren White
Ajax StreetSiren White – wireless outdoor siren with LED frame, 85–113 dB
Ajax StreetSiren Jeweller is a wireless outdoor siren that deters intruders and alerts the surroundings when an alarm is triggered. The sound level can be adjusted between 85 and 113 dB at a distance of one metre and is complemented by a brightly illuminated LED frame that flashes red during an alarm. The enclosure is rated IP54 and the siren operates from −25 °C to +60 °C, making it suitable for façade installation in Nordic climates.
StreetSiren is powered by four pre-installed CR123A batteries with a life of up to five years and can also be connected to an external 12 V supply for installations requiring mains power.
Benefits
- Adjustable sound level from 85 to 113 dB at a distance of 1 metre
- Siren duration adjustable from 3 seconds to 3 minutes
- Illuminated LED frame that flashes red during an alarm
- IP54 enclosure and operation from −25 °C to +60 °C
- Jeweller range up to 1,500 metres in open space
- Four pre-installed CR123A batteries providing up to 5 years of operation, or an external 12 V supply
Powerful audible alarm
StreetSiren Jeweller is designed to be clearly heard during a break-in or other alarm event.
The sound level has three settings, measured at a distance of 1 metre:
- Quiet – 85 dB
- Loud – 100 dB
- Very loud – 113 dB
The high sound level rapidly draws attention to the protected property.
Clear LED indication
The characteristic LED frame around the siren activates during an alarm.
Functions:
- Flashes red during an alarm
- Visible from a longer distance
- Can flash every three seconds while the system is armed
- Indication can also be disabled completely
The visual indication complements the audible signal and increases the deterrent effect.
Designed for outdoor environments
StreetSiren Jeweller is designed for year-round operation in Nordic climates.
- IP54-rated enclosure providing protection against dust and splashing water
- Operating temperature from −25 °C to +60 °C
- Humidity up to 95%
- Suitable for façades, entrances and external walls
The robust construction provides long service life even in exposed locations.
Battery operation or external power
The siren can operate completely wirelessly or be connected to an external supply through terminals inside the unit.
- Four pre-installed CR123A batteries
- External supply of 6–20 V DC, nominally 12 V
- Power consumption of approximately 25 mA in standby and approximately 0.2 A during an alarm
- Approximately 5 hours of continuous alarm operation on batteries
This makes installation flexible in both new and existing systems.
Tamper protection
StreetSiren is equipped with both a tamper switch and an accelerometer.
- Alarm if the enclosure is opened
- Alarm if the siren is removed from the wall or moved
- Alarm sent to the app and alarm receiving centre
This means that attempts to disable the siren are detected immediately.
Temperature value in the app
The siren measures the processor temperature and displays the value in the Ajax app. The permitted difference between the app value and the temperature at the installation point is 2 °C, and the value is updated when the temperature changes by at least 2 °C.
Stable wireless communication
Ajax Jeweller technology provides rapid, encrypted communication between the siren and the hub.
- Range up to 1,500 metres in open space
- Encrypted two-way communication
- GFSK modulation with ERP up to 20 mW
- Firmware updates transmitted through the Wings radio protocol
Walls, floors and other obstacles in the signal path reduce the range.
Good to know
- StreetSiren Jeweller works only with an Ajax hub. It cannot be used through the ocBridge Plus or uartBridge integration modules.
- Siren duration is set in 3-second increments from 3 seconds up to 3 minutes.
- The siren weighs 528 grams and must be secured to a load-bearing surface.

Why choose Ajax StreetSiren
- 113 dB at a distance of one metre together with the flashing LED frame provides both audible and visible deterrence
- IP54 and operation down to −25 °C make the siren suitable for Swedish outdoor environments throughout the year
- The tamper switch and accelerometer trigger an alarm if anyone attempts to open or remove the siren
- Up to 5 years of battery life allows installation where no power cable is available
PC & HiFi Örebro recommends
We recommend StreetSiren on the façades of houses, outbuildings, workshops and commercial premises where the alarm should be heard and seen from outside. Its principal strength is the combination of a high sound level, LED frame and tamper protection that triggers as soon as someone moves the unit. Ajax HomeSiren is smaller and less expensive for indoor use. Install StreetSiren high and out of reach, and remember that sound levels around 113 dB can damage hearing at close range; consider placement near windows, patios and neighbouring properties.
