DSC PC4204CF v3

Power Supply / Relay Output / Combus Repeater Module 3.0 Installation Instructions Introduction PC4204CX is a Power Supply/Relay Output/ Combus Repeater The PC4204CX provides a power output for system devices, programmable relay outputs and an output to regenerate the data signal to allow for longer wire runs. Do not use any power supply other than the PC4204CX to repower Combus. If a power supply other than the PC4204CX is used, the repower function will not operate as intended. See the control Installation Manual for details regarding this feature. Specifications Transformer 16VAC- 40VA to 80VA may be used to power the Backup battery 4Ah to 38Ah (not provided) Connects to control panel via 4-wire Combus Current draw from Combus: 30mA Four programmable relay contacts rated 2A, 30VDC Selectable battery charging current (800mA or 1.2A) AUX current: 2.2A max., with 800mA battery charge current 80VA transformer Tamper connection Installing the PC4204CX PC4204CX should be located inside a compatible cabinet, in a dry, secure location. The PC4204CX must be installed within a fire enclosure, as in EN60950. The cabinet must comply with the battery installation instructions. The cabinet should be mounted in a safe and reliable manner. A factor of 4 or higher must be provided. the following steps to mount the unit: Press the five plastic standoffs through the mounting holes the back of the cabinet. Secure the cabinet to the wall in the desired location. Use wall anchors when securing the cabinet to plaster, concrete, brick or other surfaces. Press the circuit board onto the plastic standoffs to secure module to the cabinet. the unit is mounted, wiring may be completed. Installation and Wiring The PC4204CX is intended to be PERMANENTLY CONNECTED should be installed by service personnel only. beginning to wire the unit, ensure that all power (AC and battery) is disconnected from the control panel. the following steps to complete wiring: Connect the four panel-originating Combus wires to the Connect the red, black, yellow and green wires to the RED, BLK, YEL and GRN Combus In respectively. Relay 1 is being used for Combus power, connect the wires according to the diagram below. Note that this option, jumper Con3 must also be set for 1. refer to the System Installation Manual for information on limitations regarding product use function and information on the limitations as to liability of the manufacturer. modules repowered by the PC4204CX should the black, yellow and green Combus wires connected the BLK, YEL and GRN Combus Out terminals Complete all output wiring. Connect the external tamper switch, if used. the wiring diagrams for further information. Current Calculation Chart (mA) (mA) required for connected devices = required for connected devices = required for connected devices = Combus Curr Combus Curr Combus Curr = = Combus Current = = Combus Curr = * These modules draw current from the Combus to power devices to the module. This current must be added to the total Combus See manufacturer specifications for the current draw of each Each LED assembly draws up to 20mA of current. Operation and Wiring Combus is used by the control panel and the modules to with each other. When the PC4204CX is used to repower extend the Combus, please refer to the wiring diagram for the wiring procedure. NOTE: Please follow the diagram exactly. can be home-run, connected in a daisy chain or T-tapped on the Combus. following rules MUST be followed when wiring the Combus: The Combus must be run in minimum 22-gauge wire. No module can be more than 1000′ (305m) in cable length from PC4204CX. Shielded wire should only be used in areas that present excessive noise or
