355288 – Sou-Strobe/12-24V/Re/Re/Re/MT/107dB-N CWSS-RB-S7

The combined Sounder-Strobe CWSS-RB-S7 has 32 different tones, all of which have been tested according to EN 54-3. The tone is selected via DIL switches. If the sounder is actuated via 2 control panel outputs, it can also be operated with an alternative tone. In this way, multi-stage alarming with 2 different tones can be implemented. The sound level is adjusted in 2 steps, by means of a DIL switch

Thanks to the use of LEDs, the strobe with red cap has a very long lifespan and a low power consumption. Since the strobe does not comply with EN 54-23, the signalling device has not been approved for two sense evacuation. Therefore it is used for applications where additional optical alarming is desired. If multiple sounder-strobes are used, the tones as well as the flash periods of all signalling devices on a line are synchronised in order to generate a uniform warning tone and light pulse. The current consumption of the combi signalling device depends on the tone and the operating voltage. 158 Chapter 17 Optical and Acoustic Devices, conventional 01 2E143201.SAM /1209-01/0100 . The sounder-strobe is integrated in a red plastic housing and is designed for indoor wall or ceiling mounting. The unit comes with a standard base, the cables are entered from the back or – in the case of surface mounted cabling – from the side
