Points to check prior to advising us of your requirements:
Do you have a 24V DC power supply and controls? If not you may need a AOV kit, see datasheet NL604B. If you intend to incoperate the vent into a fire alarm system. check what provision there is to facilitate this. in certain circumstances, the free area of the vent required for smoke extraction needs to be calculated, if in doubt you should speak to your fire officer.

This vent will need to be given power from a suitable control panel, or building management system to be considered as an 'AOV' or 'OV'. Numerous accessories are available, break glass control, switches and control panels, see our electrical compo.
