FIRE ALARM Faults and Repair

Fire Alarm Faults

Precision has field-based engineers who specialise in Fire Alarm fault finding and repair. We have a 24-hour staffed helpline for emergencies. We work with all makes of Fire alarm systems and carry spares for the most prevalent makes like Twinflex, Appollo, Gent, EMS, FireSmart, Kentec, Hochike, Fike and MXPro. We also work on closed protocol systems like ADT. Our engineers also carry a full stock of batteries. If your system is showing a fault, call us today to arrange for an engineer to call. We guarantee to beat any like for like quote.

Typical Faults

Faults can be in the form of a flashing light on the fire panel with a buzzer sounding or persistent activation. If you are unsure as to which device may be faulty, take a look at each Fire Detector to see if there’s a flashing light or permanent light. If it is different from other devices on your system, the device is likely to be faulty. Older Fire Alarm call points have a small breakable glass panel; these can easily be broken by accident, you will not be able to reset the Fire Panel without replacing the glass panel first. Modern Call Points have a plastic panel that you can reset. Call us for help; we may be able to explain how to reset your system over the phone.

Circuit Fault Finding
Qualified Engineers who will test and inspect your Fire Systems

Your Fire System will have inbuilt fault monitoring. An example of this is the Power Circuit; this is continuously checked to ensure that you have 230v mains power to the system. If you had a power cut, the internal system backup batteries would provide the system with enough power to run for 24 hours typically. The Fire System has an End Of Line (EOL) resistor fitted to the end of each zone. The resistor informs the panel that the cabling is intact and has not been broken. We’ve had systems where rodents have damaged the cables.

In the UK the British Standards Institute provide the standard that your system must conform to, it is BS 5839 Part 1. All our engineers are trained to this standard. We provide comprehensive services with inhouse dedicated professionals. Call us anytime for help with your fire system.

Our Engineers are trained in the process of identifying faults on all types of system. Some systems have an Event Log which can be examined to identify where faults lie. Typically, these systems are called Analogue Addressable; they are more sophisticated and provide far more information than Non-Addressable panels.

Types of faults:

  • Intermittent earthing problems in the power supply
  • Damaged to the Loop of cables that form the Fire Zone
  • Out of date backup batteries
  • Detector heads that have reached their end of life (typically 10 years)
  • Power Surge from your electrical supplier
  • Devices have become loose, which cause a Tamper Fault
  • Detector heads have become contaminated; dust can cause this
  • On wireless systems, the operating batteries are out of date
  • Alterations to buildings can cause problems with Wireless Systems, as the wireless system relies on a clear radio path
