The Hochiki CHQ-DSC2/M(SCI) is a Marine Approved Dual Sounder Controller, which has been designed to provide two sounder outputs (that can be driven separately) with full fault monitoring. The monitored input can be used for local power supply fault monitoring or as a general-purpose input. The unit utilises simple DIL switches for reliable addressing.
A back box is also available (CHQ-BACKBOX) which, when used in conjunction with the CHQ-DSC2/M(SCI), increases the IP rating to IP65.
