Using ASD for Coincidence & Redundancy Detection
Commonly known as “double knock”. Coincidence detection relies on alarm signals across two zones or between two detectors to activate before any evacuation/alarm occurs. In this instance, depending on the ASD specification, a detector or each pipe inlet can be used as a zone/address. Look at the table below to see which detectors can be used as a single zone or multiple zones/address.
How the EF-ASD can be used to protect a lift shaft
With most modern buildings being multi-level, lifts (or elevators) are a critical part of a buildings operation, forming an essential part of a life safety strategy. It is vital that lifts and lift shafts are considered critical for fire protection and evacuation strategy and therefore it is vital that a lift and lift shaft are equipped with a suitable fire detection system.
