Certified addressable sounder and visual alarm device.

The SIREND sounder is an acoustic fire alarm notification device for buildings with EN 54-3, EN 54-17 certification and CE marking.

The SIRENDL sounder is an acoustic and visual fire alarm notification device for buildings with EN 54-3, EN 54-23, EN 54-17 certification and CE marking.

These sounders have a microprocessed addressable digital module (with short-circuit isolator) SIRAYC inside, which allows them to connect to the loop. The unit operates as a single relay, identifying itself and acting in the control panel as a SIRAY.

The sounder is made of heat-resistant red ABS.

The standard configuration of the sounder sound is shown in the following figure in accordance with standard EN 54-3 (acoustic device). The same figure shows the standard configuration of the light signal in accordance with standard EN 54-23 (visual alarm device).

It is possible to change the selection of the tone and the light signal, but this operation affects the power consumption of the siren, and therefore the power consumption of the device. It is possible to change the tone and light signal selection, but this operation affects the sounder’s power consumption and, therefore, the device’s point consumption. Power consumption can be calculated using the loop element capacity calculation software.

The internal wiring and positions of other microswitchs must not be modified from those selected by the manufacturer in these instructions.
