When referring to fire alarms, there has been the continued increase in the popularity of wireless fire alarm systems due to the ease of installation and aesthetics.
Wired systems are more challenging to install and are labour intensive, none more so than a system installed in MICC (Mineral-Insulated Copper Clad cable) or also known by the original manufacturer’s name of Pyro (Pyrotenax).
The two main issues with MICC is; it is difficult to install as there are not many fire alarm installers familiar with this type of cable anymore, as most are now used to the soft cell cable such as FP200 and the cable is expensive.
At a stay at a hotel, we observed that the fire alarm was installed in MICC cable. Our first thought was how easier the installation would have been using a wireless system and how having no copper wiring on display would have enhanced the rooms and the decoration of the hotel.
In the entrance lobby we passed the fire alarm control panel and noticed several fire alarm faults, I can only presume that the faults showing were wiring faults, as we stated earlier it is very difficult to find installers with the expertise to install this type of cable.
The predicament the hotel now faces is trying to trace wiring faults, which may well be earth faults. This will require taking rooms out of service as you trace the faults.
How life would have been so much easier had the opted for a wireless fire alarm system.
If you are a consultant or end user with the need for a fire alarm system, ask yourself, is the ease of installation and aesthetics important to you, especially in buildings such as hotels? If yes, go for an EN54-25 compliant wireless fire alarm system.
