Product Overview
General Information
Power Supply Unit card for Multizone Automatically Opening Vent control panel (MZAOV).
Main Features
28V DC supply input, diode protected for reversal and independent short circuit
Maximum input current, 10A; input voltage 22 to 32VDC; configurable for either one, or both, of the inputs to be used
Inputs for two RS-485 Peripheral BUS (PBUS) circuits, not currently used; the PBUS circuits are not intended for networking
Common alarm changeover relay contacts, max 3A at 30VDC (unfused); activate when an alarm condition exists on any zone circuit or a trigger condition exists on any external Input circuit
28V output, fused at 500mA, for use by external auxiliary equipment (RDUs, PSUs, etc.)
Two 24VDC programmable and monitored sounder outputs, configurable as FARE and FWRE (Fire and Fault routing)
Common fault signal changeover relay contacts, max 3A at 30VDC (unfused); normally energised (failsafe) contacts change-over when any fault is active on the panel or in the event of total power loss
Connections for battery temperature sensor
Output connections for 12Ah or 18Ah VRLA batteries charging (temperature compensated); 27.3VDC output at 20C, max. charging current 700mA or 1.2A.
Control input from external 3-way fireman control switch, for manual control of all vents simultaneously
