The CHQ-DSC/M(SCI) is a dual sounder controller which is fully compatible with Hochiki’s ESP analogue addressable protocol.
The CHQ-DSC/M(SCI) has been designed to provide two sounder outputs with full fault monitoring. The monitored input can be used for local power supply fault monitoring or as a general-purpose input. The CHQ-DSC utilises simple DIL switches for reliable addressing.
The unit features an integral short-circuit isolator. A back box is also available (CHQ-BACKBOX) (£6.31) which, when used in conjunction with the CHQ-DSC, increases the IP rating to IP65.
