Approved Document Ref: UI-MAOV-01 Issue 1.0
PRODUCT OVERVIEW
Quality, reliability, ease of use and feature rich are attributes that are consistent across the
entire range of Haes fire alarm control panels.
The panels are available with three output options, 3 Amp, 5 Amp and 10 Amp for controlling
medium to large loads. The 3A and 5A panels can have between 1 and 4 Conventional and/or
Twin Wire (sav-wire) detector zones and will control between 1 and 4 vents. The 10A panel
can have between 1 and 8 Conventional and/or Twin Wire (sav-wire) detector zones,
controlling between 1 and 8 vents.
For the fire alarm engineer, the panel has been designed to be easy to install and to minimise
labour costs, by providing ample room for tasks such as wiring and changing batteries.
Activation is via key switch or access code, which means you should always be able to work
on the panel and the one man walk tests will help reduce the cost of maintaining the fire alarm
system.
The MAOV panel is designed to be intuitive and flexible for the fire alarm engineer to
programme and incorporates alarge 240 x 64-pixel graphical display, with an easy-to-navigate
menu system, which uses simple discernible icons in each section.
Simplicity is one of the most important aspects when considering the end user of a fire alarm
panel. The easy to read control panel, with its graphical LCD display and five marked control
buttons, and the 3-step silence functionality gives non-technical people the confidence to
correctly manage their fire alarm system.
All inputs and outputs are fully programmable and there are options to have delays to the
outputs (including vent opening). The programming features also include 3 different modes to
help reduce false alarms. Local fire authorities are demanding this type of functionality to
reduce unwanted callouts from alarm receiving centres.
The MAOV acts as an automatic multi-zone smoke vent opening control panel. The panels
are designed to control up to eight 24VDC motorised vents, which use a polarity reversal to
control vent direction. The MAOV panel can be configured to open the vents in a controlled
sequence, to aid smoke venting. The actuator output can also be configured for the control of
magnetic vents or other purposes.
The panel supports connections for up to 32 Remote Status Units (RSUs), remote control call
points and repeaters, via an RS-485 Peripheral BUS (PBUS) circuit. The PBUS circuit is not
intended for networking.
MAOV panels support a large range of conventional detectors including, Apollo, Hochiki &
Nittan.
MAOV panels are approved to European standards EN54-4, Fire Detection and Alarm
Systems –Control & Indicating Equipment.
This product has been designed and manufactured in the United Kingdom.
General Description of the Equipment
The panels have either 1 to 4 or 1 to 8 detector zones and are supplied in two different
enclosure sizes; with the 3A and 5A versions in a smaller cabinet, with space for two 12Ah
batteries and the 10A version in a larger cabinet with space for two 18Ah batteries. These
modules comply with the requirements of EN54-4: 1988 and provide temperature
compensated battery management charging.

Multizone AOV User Manual PRODUCT OVERVIEW

Approved Document Ref: UI-MAOV-01 Issue 1.0
Additional control input/output cards are available, allowing for the use of PIR sensors, to
prevent vents from closing when a trap hazard (i.e. arm or hand) exists, and rain sensors for
inclement weather.
The panels have a sheet steel enclosure, suitable for wall mounting, with a hinged and
lockable front access door. Cable entry is via 20mm knockouts located at the top and rear of
the cabinet.
Different key types are used for the door lock and the ‘Activate Controls’ key switch.
The panel is fully configurable and uses an easy to navigate menu system, which utilizes a
large 240 x 64-pixel graphical display and 5-button Up/Down/Left/Right/Enter (✓) curser
control keys for menu navigation. The panel internal sounders and external alarm sounders
are controlled by a 5-button keypad. Thecontrols are accessible by either an Activate Controls
key switch, or via a 4-digit code entry, if preferred.
The panels are designed to control up to eight 24VDC motorised vents, which use a polarity
reversal to control direction. Each output can be configured to also control magnetic vents.
