    MZAOV Multiple Zone Smoke Vent Control Panel

    The MZAOV control panels are avilable with one or two onboard smoke vent zones and choice of 3, 5 or 10 amp integral power supply. The two zone panels can be expanded to 4 or 8 zones (depending upon power supply) with extensions PCB cards.

    All MZAOV panels boast a large graphical LCD display. Each panel has been developed to provide a comprehensive and flexible solution to smoke vent control scenarios and is suitable for use with vents, windows and roof lights.

    Key Features

    • Up to 8 smoke vent zones from a single panel.
    • Choice of 3, 5 or 10amp power supply.
    • Detection zone(s) support conventional or sav-wire devices
    • Large graphical display.
    • Easy to program.
    • External input for each zone from other detection systems, to activate.
    • Monitored actuator output for each zone for controlling smoke vents.
    • Switch inputs to control wide combination of vents.
    • Fireman switch input to override all other inputs.
    • All inputs and actuator outputs monitored for Short and Open Circuit.
    • User switch inputs configurable as local fireman switches.
    • Thermostat input - Ventilation mode. Vents openable in 10% steps.
    • Actuators configurable for independent operation or linked together as per required by 12101-9 (expandable models only).
    • Optional support for Rain sensor, PIR and BMS control.
    • Staggered start of actuators to avoid the combined start-up currents from simultaneous actuator activations (expandable models only).
    • Monitoring of unused inputs and outputs can be disabled.
