How do I decide which AOV system to fit?
This can be a tricky question and your architect or development manager should be able to advise on exactly what is needed for your Smoke Vent installation.
You first need to decide what items you need to control on your system. If it is a new development you are going to to need the Smoke Vent and a Control Panel. You should then work out how many items like Smoke Detectors, etc you will need to open the smoke vent(s) separately & then class each one as a zone.
Here is an example:Example 1:
You have a single smoke vent or window which must open when the fire alarm is triggered.
This would be you have 1 zone. For a new development you will need a single Smoke Vent and a Control Panel. If there is already a fire system in place there may be a control panel and smoke detectors already fitted fitted, you will need to contact us to see if our AOV will work with already installed products. So in this situation you can link an AOV single zone to your fire system which will trigger when smoke is detected in that area. The AOV actuator when triggered will open, when reset it will close. VCS Call Points (Yellow Casing) can be added for override or system test.Example 2 :
You have 3 floors, a window on each, and a vent for a shaft on the roof.
This type of scenario would give you with 4 zones. Here you would use an AOV multi zone panel which will be able to open/close each zone independantly. Under this condition it may be that the vent should open together with any zone that is triggered. (A roof vent will be on a smoke shaft or stairwell. Opening it together with a window will then create a chimney effect clearing smoke.)
In this case you can set the AOV multi zone with zone 1 as a "master". A simple solution that will then trigger zone 1 together with any of the zones 2 - 4.
You would need to link your existing fire system or purchase a Control Panel (Multi Zone) and/or add VCS call points & smoke detectors to the AOV multi zone system to trigger. Shop AOV Control Panels and Accessories
