The HAES MZAOV-1001A is a single detection zone, non-extendable automatic opening vent (AOV) control panel with an integral 3A power supply. It is designed to control 24V DC actuators or magnets on smoke vents, windows and roof lights.
Battery backup keeps the actuators powered during a mains failure. Vent controls and indications are on the front of the panel, with a large graphical LCD and inputs for remote contacts, smoke detectors and manual controls. The detection zone can run as conventional or Twin Wire.
