Description

The principle of operation of the alarm siren is to alert with a light or sound of an alarm. The alarm control unit sends a notification, after which the siren is activated. Sirens, the signal of which is triggered in the form of a sound, are called sound sirens. Alarm devices including both sound and light — light and sound sirens. Sound alerts come in different tones, with power of up to 110 dB (pulsating or continuous). The light alert may look like a flashing light. The purpose of the siren is internal and external. The external siren works in a wide temperature range and its body is protected from moisture and is more robust than internal.  The place of attachment depends on the type of installation of the siren — external detectors must be mounted in places that are protected from any weather conditions (snow, rain, icing). The optimal power of the device depends on the place of installation of the siren for the security alarm system (indoors or outdoors) — the siren with a power up to 100 dB is used indoors. On the street, an important role is played by the distance at which the sound of the detector and the presence of extraneous noise (for example, cars) should be heard, so the external security siren should emit a sound of 100-120 dB. Sirens for burglar alarms are equipped with a tamper — a device that is activated when the case is opened or the siren is removed from the wall and thus protects the detector from intruders.

Features

The buzzer can be set to generate sound from 85 to 113 dB for an adjustable period from 3 seconds to 3 minutes1, or it can be completely silent and respond only with LED indication. StreetSiren’s hermetically sealed body has been rated IP54 level of ingress protection.

Operating principle

StreetSiren responds to alarms and tampers triggering by activating the buzzer and LED frame in less than a second. The tamper button triggers when the enclosure is opened or broken, and the accelerometer triggers when somebody’s attempting to move or dismantle the siren.

Ready to operate straight out the box: the battery is already installed, and there is no need to disassemble the siren. It can be connected to the hub in the mobile or desktop app with one click. The mounting process takes just a few minutes with SmartBracket mounting panel.
