The Marine Approved Dual Sounder Controller has been designed to provide two sounder outputs (that can be driven separately) with full fault monitoring. The unit utilises simple DIL switches for reliable addressing. A back box is also available which, when used in conjunction with the CHQ-DSC/M(SCI), increases the IP rating to IP65 for better environmental protection.
Introduction : The Ceasefire with marine approved Dual Sounder Controller is designed to monitor faults in the local power supply. It can also be used as a general-purpose monitoring system. The Dual Sounder Controller features two types of sounder alarms to alert personnel when a fault is detected.
Dual Monitoring : Features an integral SCI.
Output Info: Driven continuously or synchronised pulsed sounder drive.
Single Loop Address: Has a single digit address on the loop.
Integral SCI: Features an integral SCI.
Installation Flexibility: Smart-Fix housing system for flexibility.
