Following the change in the regulations governing fire alarm installations and the introduction of the Fire (Regulatory Reform) Order, we have been inspected and certified as competent contractors by the Electrical Contractors Association (ECA) in the installation, servicing and maintenance of fire alarm systems. The emphasis is currently on the existence of a fire Risk Assessment, as compiled by the end user and there are a number of very helpful documents available to those whose responsibility it is to provide the risk assessment. The risk assessment and other related publications are available to download on the HM Government website http://www.communities.gov.uk/fire/firesafety/ .
We can provide copies of these documents if required and we can provide assistance to the "responsible person" whose duty it is to compile the fire Risk Assessment. The importance of a fire Risk Assessment cannot be over-emphasised and it is a legal requirement to have one in place for commercial establishments.
As a registered and regularly inspected security installer with the ECA, we offer several different fire alarm options, depending on your requirements. We use tried and tested fire alarm equipment provided by leading manufacturers and backed up by their guarantees. Installations are carried out by trained and security vetted staff and maintained following installation with regular visits and checks to ensure that the installation remains trouble free.

The basic technology is non-addressable which is found more often in smaller buildings due to it being more cost effective. A non-addressable system is simply comprised of fire zones. A zone is how a building is split up, to help speed up identification of the location of a fire. For example, if a building was not zoned, then in the case of a fire, the whole building would have to be searched instead of the rescue services being directed to the exact zone area by the control panel. This would dramatically slow up the location process and would result in more damage and possibly loss of life.
Each zone is made up of a grouping of smoke/heat detectors and manual callpoints. In the event of a fire being detected, either automatically by a detector or manually by a person discovering a fire and operating a manual callpoint, it will cause the control panel to go into fire alarm mode which will then operate the alarm sounders thus alerting the occupants. The zone in fire alarm mode would then have to be checked to establish the exact detector that caused the alarm. If a detector was the cause, a red LED would be illuminated on the detector itself.
Analogue Addressable System
This technology is far more advanced and is normally found in the larger premises. This is called Analogue Addressable and will pin point the exact location of a fire through zoning and also the detector in the vicinity of the fire, having its own number (address) and text allocated to it.
When a detector on the loop senses a fire, information is passed back to the control panel, which is then processed and a decision is made by the panel, not the detector, whether it is a fire or not. Individual detectors can have their threshold levels altered, so for example, they can be less sensitive during the day and more at night if required. Another advantage it has over non addressable technology is that individual detectors can be isolated instead of an entire zone. This system can dramatically reduce unwanted alarms and unlike non addressable systems will alert the user if a detector has become faulty. In the event of a fire or fault, the control panel offers text description of the condition, unlike the non addressable, which will only illuminate relevant LED·s. This makes the location of fire and faults much quicker.
There are also wire free radio based analogue addressable fire systems, which have all the benefits of a hard wire system, but with the obvious advantage of no cabling required to all the devices. This is an ideal option for listed buildings such as churches, where cable runs would look unsightly. There is also no damage to the building or mess from drilling
Fire Alarm Devices
A smoke detector is a device that detects smoke and issues a signal back to the fire alarm system
A heat detector is a device that responds to changes in ambient temperature. Typically, if the ambient temperature rises above a predetermined threshold an alarm signal is triggered. Most commonly found in kitchens, boiler rooms or unclean environments.
In the event of a fire a person would break the glass in the unit which in turn activates the fire alarm. Most commonly found at all exits to the outside of a building.
Normally red and alerts occupants audibly to a fire. These can be supplemented by visual alarms (flashing beacons) where areas can be normally noisy i.e. factories or where they are required for DDA compliance. The general sound level required is 65 DBa, or 75 DBa in a room where people sleep.
The sounder can also be integrated with a smoke or heat detector, making it an ideal option for bedrooms where the owner might not want to see a red sounder on the wall.
