Sirens for alarm
The siren as part of the alarm system is one of the most effective types of security devices that protects the premises from intrusions and thefts.
A security siren for an alarm is a sound or light annunciator with which the security system reports an alarm with sound or light, respectively.
The burglar alarm siren is responsible for the following actions:
- The siren is able to scare away an intruder when trying to break in with its sound and light.
- Attracting the attention of others to the incident and informing about an unforeseen situation — about a fire, flood or burglary.
Types of sirens for signaling
There are following types of sirens for the security alarm:
- Indoor sirens for indoor installation.
- Street alarms.
The sound of the indoor siren is less harsh and loud than that of the outdoor siren. Often, an indoor siren only sounds an alarm, while an outdoor siren is equipped with LEDs. A bright indicator light attracts attention not only at night, when it can be seen from afar, but also during the day. Also, the body of the outdoor siren is additionally protected from external factors: rain, dust, etc.
The location of the siren is no less important than its characteristics. You need to mount the siren in a place that is hard to reach for an intruder so that he cannot turn off or damage the device.
Sirens are also distinguished by their power source. There are two options: powering the device from the battery and from the network. Battery-powered sirens require periodic recharging or replacement of the power source. Alarm signals in such devices are transmitted via a radio channel.
Mains-powered sirens rely on rolling blackouts and require wiring.
Only experienced security company specialists can determine the optimal type of siren for a particular type of building. Installation engineers will select the correct place to install the sirens and the right number of them.
Alarm sirens by Ajax
Sirens are used in alarm systems to scare off intruders who are trying to get into the premises under guard. Also, sirens attract the attention of neighbors to the incident.
What security sirens are available for Ajax alarms
The Ajax security system includes several types of sirens for protecting premises. Both wired and wireless sirens are available for both outdoor and indoor installations.
Wired sirens of the Ajax security system operate using the two-way secure Fibra protocol, the connection range of which is up to 2 km. Thanks to the bus connection method, Fibra instantly delivers alarm messages, even if 100 devices are connected to the system. The protocol encrypts transmitted data and verifies all communication sessions with devices, which helps prevent sabotage and siren substitution. The Fibra protocol provides for regular polling of the siren by the control panel at a specified frequency to control communication and the ability to display device statuses in real time in Ajax applications.
Ajax wireless security sirens operate at a distance of up to 2 km from the control panel, in the absence of obstacles. Thanks to Jeweler radio technology, the siren’s battery can last up to 7 years without replacement. Ajax wireless sirens use several radio frequencies for operation in order to switch the system to a free frequency in case of jamming.
