Fire Alarms

Protecting your property against fire is vital, and at Sentinel Security, we have a range of fire alarm systems that can help to give you peace of mind. We install and maintain all major brands of fire detection systems and we are committed to consistently providing world class service to our domestic, commercial and industrial clients. 

We offer customised solutions for homes and businesses, based on our thorough understanding of your specific requirements. Our priority is to provide affordable home and fire safety equipment that is high on performance and delivered on time, and all of our fire safety detection and prevention tools are user friendly and can be used in different areas.

What sort of Fire Alarm do you need?

 The type of fire alarm that will work best for you depends upon your unique set-up and special requirements. We will inspect your premises and discuss the options with you to find the right solution for you.

 Conventional fire alarms:

 We supply and install a range of conventional fire alarm systems, including the following:

  • Conventional Fire Alarm Control Panels. A conventional fire alarm control panel links to several lines of fire, heat and smoke detectors and manual call points, referred to as detection zones. Depending on the responses received from the detection zones, the control panel may activate a number of sounder or alarm systems. This is an effective solution for small buildings, as it can indicate the zone in which a problem has been detected and it usually supports up to 40 zones, each covering an area of up to 2000 sq metres. This system is run from mains power, with battery back up.

  • Smoke Detectors. We work with a range of smoke detectors, including optical smoke detectors, which may be triggered by a light beam that activates the alarm if blocked by smoke or by light scatter caused by the smoke. Ionisation smoke detectors are slightly more sensitive, triggering the alarm when smoke enters the ionisation chamber within the detector and neutralises the ionised air there. Another option is the Reflected Beam smoke detector, which is based on the principle of light obscuration and consists of a transceiver (transmitter/receiver) unit that projects, monitors and receives a beam of light reflected across the protected area. The type of detector that works best in your premises will depend upon the environment of your building and we can advise on this.

  • Heat Detectors. Rate-of-Rise (ROR) heat detectors operate by detecting a rapid rise in temperature, so that an alarm is activated when the temperature rises by 6.7° to 8.3°C per minute, irrespective of the starting temperature.
  • Fixed Heat Detectors. Fixed heat detectors activate an alarm when the heat sensitive eutectic alloy they contain reaches the eutectic point at which it changes state from a solid to a liquid. These devices are often used in boiler rooms, and the most common fixed temperature point for electrically connected heat detectors is 58°C.
  • Break Glass Units. A break glass unit allows for manual setting off of a fire alarm, should it be seen before it activates a smoke or heat detector.

  • Fire Doors. We often suggest magnetic smoke door holders, which are comprised of wall or floor mounted solenoids or electromagnets, controlled by a fire alarm system or detection component that magnetically secures spring-loaded self-closing smoke tight doors in the open position. These are designed to de-magnetise and allow automatic closure of the door on command from the fire control.

Addressable Fire Alarms:

Addressable fire alarms are an excellent option in larger and more complex buildings, as these offer a faster and more precise identification of the location of a fire, as well as easier maintenance. An addressable fire alarm allows one pair of wires to be connected to a large number of devices across the system, providing cost savings in the wiring of large systems. 

In an addressable fire alarm system, the wiring is looped, and this connects to the control panel at each end. All detectors, call points, sounders and interface modules are wired directly to the loop, each having its own address. The control panel communicates with each device on the loop, and if a warning or fault condition is signalled, or if communications with a detector are lost, the alarm is triggered. The loop can be powered from each end so that if the loop is broken at any point, no devices are lost.

Fire Alarm Monitoring

 Monitored fire alarm systems can be ideal for commercial premises and large sites. If you are responsible for providing a fire alarm system for offices or a corporate area, you will need to meet specific requirements, and we can help you with this. You will not require a landline, as we can operate our systems through GSM mobile phone company, connecting to monitoring stations that will visit the premises and/or alert emergency services when necessary.

 Time is of the essence in the event of fire, and 24//7 alarm monitoring delivers the reassurance that we will respond with speed and efficiency when needed. Our highly trained team of operators will monitor all fire alarm activations in line with current European standards, and ensure the fire brigade is swiftly alerted and dispatched. Whether your premises are occupied or vacant, we will act fast to mobile a quick emergency response and minimise danger to life and damage to property.
