Fire Alarm Installations    

D I S Contractors are not only installers of conventional, addressable fire alarm systems we are also installers of radio fire alarm systems, also known as wireless or wire-free technology. Particularly suited to locations where wire connections are unsightly or impractical, radio fire alarms provide highly effective protection from fire.

Long-life, wire-free installations are ideal for preserving the fabric of older buildings. Wireless fire alarm systems are also the ideal solution in large buildings such as hospitals; where lengthy cable routes would impose needless extra cost or where installation needs to be free of disruption.

About wireless systems

*       The wire free devices are battery powered and provide long lasting, reliable and sophisticated technology.

*       Radio alarms are perfect for heritage buildings as well as for those that would suffer from the disruption of added cable routes such as hospitals or schools.

*       Wire free technology is particularly suitable for temporary installations.

*       The battery life of call points and smoke detectors can be up to ten years.

*       Sounders have a design life of between five and seven years depending on the selected model.

Fire Alarm Testing

A working fire alarm system should give enough warning to save lives and hopefully buy fire fighters enough time to limit property damage. Periodic testing, backed up by regular user checks will ensure that the system is always protecting people and property.

Over time, smoke detectors become less sensitive. Standby batteries in control panels become weak and general faults can develop.

Regular checks are an essential part of fire alarm system maintenance.

Periodic testing of fire alarm systems is a requirement for a local authority fire certificate.

The sensitivity of detectors on a poorly maintained, or neglected fire alarm system may result in the system not going into alarm condition should a fire develop, that could be deadly.

Tests Carried Out

All smoke and heat detectors will be tested for functionality. Bells and sounders will be operated and assessed to ensure that they provide sufficient sound levels in all areas. Fire panels, their batteries and all cable joints where accessible will be checked for integrity and functionality.
