Product Overview

Utilising the same detection circuit technology as our EN54 approved fire control panels, Haes have developed the AOV range to provide a comprehensive solution for smoke ventilation system control.

AOV panels are designed to control 24vdc actuators or magnets. Typically used in staircase lobbies, corridors or smoke extract shafts.

The single detector circuit can be set as Twin Wire enabling detectors and sounders to be connected to the same cables.

The panel has battery backup capability and assures that actuators can be powered in the event of mains failure. 3A, 5A and 10A PSU versions are available for controlling small, medium and larger loads.

Vent controls and indications are provided on the front of the panel with integral control inputs to accept signals from remote contacts, smoke detectors, manual controls and emergency push buttons.

All models include false alarm management mode.

The high spec versions also include 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 of dampers / smoke louvres. All inputs and outputs are included in a single, off the shelf unit with no additional cards or modules required.
