Commercial
fire system installation
Fire is a threat to any business, so much so that 80% of businesses fail within 18 months after a major incident. With early detection lives, property and businesses can be saved.
Not only is it a legal requirement to assess the threat of fire but businesses must install a fire alarm system that mitigates the risk. These rules apply to SMEs and multinational organisations.
At Shrewsbury Electricians we install and maintain fire alarm systems for customers throughout the county, designed to their unique business requirements.
Different types of fire alarm systems
All Fire Alarm Systems essentially operate on the same principle. If a detector detects smoke or heat or someone operates a break glass unit (manual break point), then alarm sounders operate to warn others in the building that there may be a fire and to evacuate. It may also incorporate remote signaling equipment which would alert the fire brigade via a central station.
Fire Alarm Systems can be broken down into four categories:
- Conventional
- Addressable
- Wireless systems
Conventional Fire Alarm System
A conventional fire alarm system has a number of call points and detectors wired to a fire alarm panel connected to zones. A zone is a circuit that alerts the user where a fire has happened. The fire brigade use this information when fighting the fire.
Addressable Systems
An addressable system is the same as a conventional fire alarm system. The difference is that a control panel can identify which detector or call point set off the alarm.
Wireless Fire Alarm System
Wireless fire alarm systems remove the need for wires, instead sensors, detectors and call points are all interconnected via radio communication. It makes setup easier but still requires power connected to each device.
Types of fire alarm sensors
There are a number of different fire alarm sensors on that market, each with their own unique way of sensing the presence of fire. At Shropshire Electrical Services, we’ll design the best fire alarm system that matches with your buildings layout.
Heat Detectors
Heat sensitive detectors
Within this category there are two types of heat sensors.
The first kind are point detectors, they either sense a fixed temperature rate or the rate of temperature rise.
Linear detectors are the second type of fire alarm system heat detector, they use heat sensitive cable. When the cable insulation melts, this creates a short-circuit and raises the alarm.
Smoke Detectors
There are a variety of smoke detectors available on the market, let’s take a look at the most common types we use in a fire alarm system installation:
Ionisation alarms are the most common type of fire sensor. They use a small radioactive source to generate a current. When smoke is present this causes the current inside the unit to change, sounding the alarm. Their sensitivity doesn’t make them suitable for kitchens.
Optical alarms use infrared beams to detect smoke. They’re more expensive than ionisation alarms but can be used in most of the house.
Combination smoke detectors use one of the methods above with a heat sensor. The information is taken from both sources then combined using a complex algorithm to compute if fire has been detected.
