Fire Alarm Systems

Tcom Fire & Security are specialists in the design, installation and maintenance of Automatic Fire Detection Systems & Emergency Escape Lighting. TCom will ensure that your premises or property are adequately protected and any system is professionally installed and maintained to satisfy current safety laws governing fire detection and safety within the office, retail, commercial or industrial building, hotel or multi-occupancy dwelling environment.

Our specialist design, installation and maintenance team utilise the following Codes of Practice to satisfy full compliance of statutory regulations on Fire Detection and Emergency Lighting Systems. Compliance to the required standards is confirmed with the issue of a Certificate of Compliance on completion, following the commissioning and handover of any system.

The following Codes of Practice demonstrate the requirement for competency in critical areas such as Design and Installation, Commissioning and Inspection Routines and a robust Local Management Process to guarantee optimum performance and reliability from any system.

Fire Detection System – Codes of Practice

BS 5839-1:2002+Amendment 2:2008: Design, Installation, Commissioning and Maintenance of Fire Detection and Alarms for Buildings.

BS 5839-6:2004: Design, Installation, Commissioning and Maintenance of Fire Detection and Alarms in Dwellings.

BS 5839-8:2008 BS 5839-6:2004: Design, Installation, Commissioning and Maintenance of Voice Alarm Systems.

Fire Alarms – System Types

Conventional

A system designed with separate detection and sounder zones/circuits. Suitable for a small shop or office unit, warehouse, garage and house/flat conversions.

Twin Wire

A system designed with zones/circuits combining both detectors and sounders. Suitable for a larger shop or office unit, warehouse, garage and house/flat conversions where there would be a cable cost-saving benefit.

Addressable

A system designed to transmit data over twin wire detector loops. Each detector has a digital address and is identified at the control point with a detector number and the name/location of each detector. Suitable for larger premises such as industrial units, distribution warehouses, factories, office blocks, apartment blocks and hotels.

Wireless

A system designed without cable. Each detector or sounder is fitted with a long-life battery that is continually monitored for replacement. Each detector also has an in-built radio transceiver providing the data transmission path with the control point/s. Detector number and the name/location of each detector is provided at the control point. Suitable for multiple building locations, schools and colleges.

Remote Monitoring

Every system needs monitoring of some description. Managers and landlords should have a method of response to any alarm activation. A connection to an Alarm Receiving Centre (ARC) is recommended whereby the system events are communicated to the ARC, and a controller will in turn initiate the required response by contacting the Fire Authorities and Keyholders.

  • SMS Text or Speech Dialer Modem: for Direct contact with landlord/managers/keyholders.
  • Modem: (Non-monitored Telephone line) for ARC contact - Fire Authorities - Keyholders.
  • BT RedCare Classic (Monitored Line) for ARC contact - Fire Authorities - Keyholders.
  • BT RedCare GSM (Monitored Line & GSM Backup) for ARC contact - Fire Authorities - Keyholders.
  • CSL DualCom (Monitored GSM & Line Backup) for ARC contact – Fire Authorities – Keyholders.

Fire Alarms – Design Grades

 

Detection System Grades are based upon the risk of fire and the threat to life. This is determined by the contents, structure, layout and fabric of any building and, in the event of a fire, the potential for loss of life. As part of a Risk Assessment, it is obligatory that consideration is given to these factors. The system grade will be determined by the number of negatives highlighted. The more negatives, the higher the grade. Grade F is the lowest, rising up to the highest, Grade A.

Grade F

System of one or more battery-powered smoke alarms (and heat alarms if required)

Grade E

System of inter-linked mains-powered smoke alarms (and heat alarms if required) without a standby power supply. This type of system is not recommended by TCom

Grade D

System incorporating one or more interlinked mains-powered smoke alarms and/or heat alarms with integral standby power supply. The inter-link can be hardwired or radio-interlinked

Grade C

System consisting of smoke or heat detectors and sounders connected to a common power supply, comprising normal mains and standby power supply, with central control equipment

Grade B

Fire detection and alarm system comprising fire detectors (other than smoke alarms), fire alarm sounders and control and indicating equipment to either BS EN 54-2 (and power supply to BS EN 54-4) or to Annex C of BS 5839: Pt.6

Grade A

Fire detection system incorporating control and indicating equipment to BS EN 54-2 and power supply to BS EN 54-4, installed to BS 5839: Pt.1 with some minor exceptions.

System/s in Dwellings are specified and identified by Grade and Category. E.g. Grade C - Cat LD1

System/s in Business Premises are similarly specified and identified E.g. Grade A - Cat L3

Protection Categories to Dwellings are as follows

  • LD1 - A system installed throughout the dwelling, incorporating detectors in all circulation spaces that form part of the escape routes from the dwelling, and in all rooms and areas in which fire might start, other than toilets, bathrooms and shower rooms
  • LD2 - A system incorporating detectors in all circulation spaces that form part of the escape routes from the dwelling, and in all rooms or areas that present a high risk of fire
  • LD3 - A system incorporating detectors in all circulation spaces that form part of the escape routes from the dwelling.

Protection Categories to Business Premises are as follows

Category "M" systems are where manual detection points only are fitted and do not incorporate any automatic detection.

Category "L" systems are for the protection of "Life" as follows:

  • L1 - Manual detection at defined positions and automatic detection in all areas of the protected premises
  • L2 - Manual detection at defined positions and automatic detection in all escape routes, rooms which open on to escape routes and high-risk or fire-hazard areas of the protected premises
  • L3 - Manual detection at defined positions and automatic detection in all escape routes and rooms which open on to escape routes of the protected premises
  • L4 - Manual detection at defined positions and automatic detection in all escape routes of the protected premises
  • L5 - Manual detection at defined positions and automatic detection in areas designed to satisfy a specific fire safety objective of the protected premises.

Category "P" systems are for the protection of "Property" as follows:

  • P1 - Automatic fire detection fitted in all areas of the building
  • P2 - Automatic fire detection fitted in defined areas of the building.

Fire Alarms - Monitoring Options

Alarms & CCTV Remote Monitoring – Codes of Practice

The following Codes of Practice demonstrate the requirement for competency in critical areas of Alarm Receiving & Remote Video Response Centre Systems, Management and Procedures.

BS EN 50518-3:2011: Monitoring and Alarm Receiving Centre - Procedures and Operational Requirements.

BS 8418:2010: Installation and Remote Monitoring of detector-activated CCTV systems - Code of practice.

Fire Detection System – Handover and Certification

Once the system has been commissioned, the fire technician will demonstrate to The Responsible Person (please see below) how to use the system. As a minimum, this will include how to operate the panel and how to carry out weekly testing of the system.

Once the system is fully complete and the installation is finished, the design, installation and commissioning certificates will be handed over to the customer, together with a certificate of conformity.

You will also receive a logbook for the on-going testing and recording of system events along with any user manuals, drawings and guides.

A zone legend, normally a drawing, will also be placed near the panel to indicate where all the fire zones are located within the building.

Fire Detection System – After Sales Service & Maintenance

On-going corrective and preventive maintenance of the system will form part of your contract. Preventative maintenance checks will normally be carried out every six months as a minimum, but some systems will need a visit every three months. You will be informed when these tests are to take place. Under a current maintenance contract, we will be obliged to include a call-out facility with a minimum response time (the standard is eight hours) to ensure any emergency breakdowns are attended to in an efficient manner.

Fire Detection System – Warranty

New systems will carry a comprehensive labour and parts warranty of at least 12 months.

The Responsible Person

Under The Regulatory Reform Fire Safety Law Order and as per British standards, every fire system must be managed by a Responsible Person. This person is responsible for weekly testing of the system and managing of the maintenance carried out by the fire alarm company. There should be two Responsible Persons, or the Responsible Person should train at least one other person in how to test and operate the systems in case of absence, holidays etc.
