Having motion and door sensors is essential, but in the event of an intrusion, silence isn't always your best ally. You need something that makes the difference between an attempted robbery and a hasty escape. That something is an outdoor siren .
The siren doesn't just alert the neighbors and yourself; its main function is psychological and deterrent . A thief who sees a professional siren on the facade knows that house isn't an easy target. And if they decide to try, the noise must be unbearable.
At tiendacables.com , we are committed to the Ajax StreetSiren , a device that combines Grade 2 engineering, sound power and a wireless installation that breaks with the limitations of traditional alarms.
1. Power You Can Feel: 113 dB Sound Pressure
When the Ajax StreetSiren is activated, it doesn't go unnoticed. With a configurable power output ranging from 85 to 113 dB (at 1 meter distance), it generates a noise level comparable to that of a rock concert or a jackhammer.
-
Customizable Duration: Through the Ajax app, you can configure how long you want the alarm to sound, from a brief 3 seconds to 3 continuous minutes.
-
LED Visual Signaling: It's not just noise. Its frame of flashing LEDs illuminates bright red during an alarm, visually marking the affected property—crucial for police or security services to quickly locate the home at night.
2. Jeweller Technology: Professional Wireless Security
Forget about drilling through the entire facade to run power and data cables. The StreetSiren uses Ajax's Jeweller radio protocol, renowned for its stability and range.
-
Massive Range: It can communicate with the Hub at a distance of up to 2,000 meters in open space. This allows you to install it on the highest and most visible part of your facade, garage, or industrial building without worrying about signal loss.
-
Autonomy and Flexibility: It operates on four pre-installed CR123A batteries that offer years of autonomy. Prefer to wire it? It also supports external 12V DC power, allowing you to use the batteries as an emergency backup.
3. A Tank Against Climate and Sabotage
Being outdoors, the siren is the most exposed component of the system. Ajax has designed it to withstand both the elements and intruders.
-
IP54 certified: It is protected against dust and water splashes, and operates perfectly in an extreme temperature range, from -25ºC to +50ºC . Neither the harshest winter nor the hottest summer will affect its performance.
-
Anti-Tamper: If an intruder tries to pull the siren off the wall or open the housing, the internal accelerometer and tamper will activate the alarm immediately, even if the system is disarmed (depending on the configuration).
4. Everyday Intelligence
Beyond emergencies, the StreetSiren is useful in everyday life. You can configure it to emit a short beep and LED signal when arming or disarming the system. It's the perfect audible confirmation that your home is protected before you leave, without needing to check your phone.
