Description
Model PRP/DSC/ESP is a Dual Sounder Controller, which is fully compatible with Hochiki’s ESP analogue addressable protocol. The Dual Circuit Sounder Controller 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 PRP/DSC/ESP utilizes simple DIL switches for reliable addressing and it is available unboxed (as illustrated above) however a separate IP67 rated enclosure is available.
