The HAES MZAOV 10A (MZAOV-1003) is a multi detection zone automatic opening vent (AOV) control panel with a 10A integral power supply. It is supplied with two detection zones, extendable up to 8, and has a large graphical LCD display.
It is designed for smoke vent control and is suitable for use with vents, windows and roof lights. Detection zones can be conventional or Twin Wire, and it accepts inputs from other detection systems such as a fire alarm panel.
Key features
- 10A integral PSU
- Large graphical display, easy to program
- Up to 8 detection zones, conventional and Twin Wire
- Up to 8 external inputs from other detection systems
- Up to 8 monitored actuator outputs for controlling smoke vents
