CHQ-PCM-DIN(SCI) Instructions

2-3-0-1156/ISS2/OCT11 PLANT CONTROL MODULE INSTALLATION INSTRUCTIONS Products covered: CHQ-PCM(SCI), CHQ-PCM/DIN(SCI) The CHQ-PCM(SCI) is a loop powered output module with four independent change-over relay outputs, with N/O and N/C volt free contacts. These outputs can be driven separately under the control of the fire alarm panel and can be used for the control of devices such as dampers or for plant and equipment shutdown. 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. Components Standard "Smart-Fix" Modules are supplied as two individual components (see Fig 1 & 2). DIN versions are supplied as one unit (see Fig 3).
