Adjusting Sensitivity; Operation; Maintenance; Technical Specifications - quiko QK-CTSIR Instructions For Installing And Using

Sensitivity of the CTSIR detector in recognising sirens can be adjusted with the "sensitivity" trimmer.
The standard trimmer setting done in the factory is at half stroke which is quite enough in the majority of cases.
However, in installations where the CTSIR detector is installed a long way from the automatism or there is a great deal of acoustic pollution,
we suggest adjusting sensitivity with some real tests with sirens.
When turning the power on, the amber coloured LED flashes slowly meaning that the CTSIR detector is in the standby status.
The light of the amber coloured LED becomes fixed when the intensity of the sound received by the CTSIR detector is higher than the
threshold set with the "sensitivity" trimmer; after this it analyses the tone of the sound to see whether or not it is a siren.
When the CTSIR detector identifies the sound of a siren, the relay switches, supplying a closed contact; the amber coloured LED turns off
and the green LED turns on.
Periodically check that the CTSIR detector is working properly as it provides a very important service, allowing emergency vehicles quick
access.
The CTSIR detector is not, however, a safety device, by which we mean it is not the only device a system has for evacuating areas in an
emergency. In fact, it must always been installed in conjunction with safety devices certified in accordance with the applicable standards.
