Conventional Fire Alarms

Conventional fire alarms are considered a basic system to alert people in the building of a fire. The conventional fire alarm has alarm points, smoke alarms and a control panel to detect a fire which tells you of a zone location for the fire.

Detectors and manual call points are wired separately from the alarm sounders and all devices are connected to radial circuits starting at the panel and continuing through the zone to the final (end of line) device. The end of line is how the cables are monitored. If a single detector is activated the zone it is in will be activated on the fire panel.

If you have a small premises and a basic floorplan, the conventional fire alarm could be ideal for your requirements and budget due to the premises needing minimal points and detectors would be needed.

Another version of conventional fire systems are bi-wire or twin-wire systems. For this system alarm sounders and detectors can be combined on the same pair of cables to save on installation costs. OHEAP will be happy to discuss these options further with you.

Aspirating Fire Alarms

Through a network of pipes to draw air through, aspirating fire alarms and smoke detectors carry air to a detector which tests the air sample for smoke particles. The alarm will continuously sample the air for early detection especially in challenging environments including unmanned data rooms and warehouses with high ceilings. Aspiration can also be fitted in voids and below floors tiles to ensure all areas are covered.

Aspirating systems are available in a range of variants suited for different environments. If you have a key risk area, this can be covered by strategically placed sampling zones along with a high-power fan which ensures a regular intake of air. This is as opposed to waiting for smoke to drift towards a detector.

Wireless Fire Alarms

Wireless fire alarms also known as radio alarms utilise radio frequencies to control the detectors in your building removing the need to cable to install.

Through radio connectivity all detectors and call points are then in contact with the main control panel. The signal strength is preserved through the use of a number of frequencies resulting in it never being blocked or weakened.

Wireless fire alarm systems are simpler to install however they have a higher cost compared to a standard alarm system due to its technology.

Addressable Fire Alarms

The addressable fire alarm is ideal for telling you exactly which detector or call point has been set off. Due to this, the building can be evacuated safely as people in the building will know where the fire is located and to avoid that area. It also saves the authorities time figuring out where the fire is and ensures the fire is tackled quicker knowing the precise location of the fire.

Each connection is part of a single loop, if one end of the cabling or connection fails, a signal can still run the opposite way which ensures all detectors remain active.

The addressable has minimal cabling which makes adding additional devices to the set up easy to do.

Gas Suppression Fire Alarms

Gas suppression fire alarms are used for locations of buildings that have the greatest risk from a fire and are unoccupied. The fire alarm can detect a fire by monitoring the area and suppressants can be released when a fire is detected. This protects people in the building, the building and company assets before the fire even has a chance to spread.


How do I know which alarm system I need?

This will all depend on number of factors unique to your business. Following an initial consultation our Fire Protection Consultants will be able to recommend the best system for your business and budget.  

Do my alarms need servicing?

British Standard 5839 states that you should have your fire alarm system serviced at least every 6 months.  Our Fire Alarm Engineers will test your entire system as discreetly as possible in order to minimise disruption to your business.  

How often does my alarm need testing?

You should carry out weekly fire alarm tests to ensure your system is working correctly. You should activate at least one fire alarm call-point and check that the alarm sounds and the panel receives the signal testing a different call point each week. Make sure you log the test in your fire alarm log book.
