Hochiki ESP Plant Control Module (with SCI)

The CHQ-PCM(SCI) is a loop powered input/output module with four independent change-over relay outputs and four monitored inputs

The outputs feature N/O and N/C volt free contacts and can be driven separately under the control of the fire alarm panel, to be used for the control of devices such as dampers or for plant and equipment shutdown

The four inputs are provided for local fire and fault monitoring and these are fully monitored for open and short circuit, which if required, can be enabled or disabled in pairs using a two-way DIL switch

Note:- The state of the relay contacts will be indeterminate until the unit is powered

The unit is also available in a DIN Rail mountable enclosure (CHQ-PCM/DIN(SCI)). A back box is also available (CHQ-BACKBOX) which, when used in conjunction with the CHQ-PCM(SCI), increases the IP rating to IP65

When using heavy cables we recommend the use of the SMB-1 Module Enclosure inconjunction with the SMB-ADAPTOR plate
