The loop sounder FI700/WM66/SOUR is activated and supplied via the ADM loop with Labor Strauss/700 protocol. Depending on the parameter setup of the fire detection control panel and the system condition, the panel can activate one of three tones. If several sounders are actuated in parallel, they are synchronised by the fire detection control panel to generate a uniform warning tone. The integrated dual-isolator disconnects the loop at short circuit on the loop line
The sounder is integrated in a red plastic housing, and thanks to its dust and water protected design with protection class IP66, it is suitable for harsh environmental conditions
