Haes MZAOV AOV Control Panels are multi-zone Automatic Opening Vent (AOV) panels with integrated power supply that are designed to control 24Vdc actuators or magnets. 

These panels have battery backup capability and assure that actuators can be powered in the event of a mains failure.

Vent controls and indications are provided on the front of Haes MZAOV AOV Control Panels  with a large graphical LCD display and integral control inputs to accept signals from remote contacts, smoke detectors and manual controls.

Optional support for rain sensor and PIR inputs for environmental control and trap injury protection, plus 0/10v inputs and outputs to allow control interfacing with BMS systems and positional control act output.

The MZAOV control panel range has been developed to provide a comprehensive solution to smoke vent control scenarios and are available with 3, 5 or 10 amp integral PSU for small, medium and larger loads. 

Haes MZAOV AOV Control Panels are available as a single zone panel or in multi-zone versions supporting 1-2 zones, 2-4 zones, or 2-8 zones.
