If you are thinking about upgrading, fitting, or getting your Fire Alarm System Serviced,it might be time to evaluate your over-all Fire Safety and consider the following:
- There is a fundamental difference between how an intruder alarm and fire alarm is used;
The intruder alarm is set and unset every day and therefore is looked at, given attention and if a fault shows, it is noticed and dealt with. The fire alarm is passive and generally unseen. It is not set and unset and if a fault occurs it can be ignored, or silenced and left.
Therefore it is vital that there is a person with responsibility for the condition of the fire alarm.
The Irish Fire Standard ; I.S.3218:2013 deals with this and specifies that a “responsible person” is appointed.
The “responsible person” is charged with daily attention, i.e looking at the panel to note any faults, weekly attention; testing the sounders and warning devices and also ensuring the system is maintained by a qualified person, generally quarterly.
