There are four main types of fire alarm systems you can implement into your business.
A conventional fire alarm system will spilt the building up into zones, generally four but there can be a number of zones specific to the building size. When a detector is activated, the control panel will identify which zone the signal is coming from; the area will have to be searched manually for the source.
A two wire fire alarm system is very similar to a conventional one, with a few important differences. The call points and alarm devices will be wire on the same set of cables going back to the control panel. Therefor, when the control panel receives an activation, it will know the exact location which is coming from. This eliminates the needs for a manual search; however it is often more expensive to install.
An analogue-addressable system removes the needs to view the building in zones, these alarm systems can give details on each individual detector. These types of systems are designed for large building in which finding the source of a fire needs to be found as fast as possible. Each device will have a unique address which will be recognised by the control panel. This gives an exact pin point location of the source is a detection device is to be triggered.
A wireless online fire alarm system is also allowed within the fire safety regulations; however, they are often high in price to install; especially is you are in a large building. Having no cables make it very easy to see which part of the system is not performing. This can save you money on cable testing and inspections but the initial costs will be much greater.
