The CHQ-DSC2(SCI) is a Dual Sounder Controller designed to provide two independently driven sounder outputs with comprehensive fault monitoring. The monitored input can be used for local power supply fault detection or as a general-purpose input.
The unit uses simple DIL switches for reliable addressing. An optional back box (CHQ-BACKBOX) can be fitted to increase the IP rating to IP65 when used with the CHQ-DSC2(SCI).
