The suffering and financial losses of fires are incalculable. Installing a reliable and effective fire detection and alarm systems are essential in your home, office, factory or school. We install domestic and commercial types of fire alarm systems to comply with the necessary requirements needed.
Fire is among the most serious dangers we face. According to Home Office statistics, every year there are more than 100,000 fires in buildings, and around 600 people lose their lives. The suffering and financial losses are incalculable - reliable and effective fire detection and alarm systems are essential.
We install domestic and commercial fire alarm systems to comply with the necessary requirements needed.
Are usually smoke and heat detectors in various places throughout the home which are interlinked with sounders inside the detectors so wherever the fire occurs you will hear from all detectors throughout your property.
Range from small interlinking systems similar to the domestic systems leading to big fire alarm panel installations which can be as big as you want them to be which are very common whish blocks of flats for communal ways ext.
New Build Properties & Materially Altered Dwellings,

Mains alarms with battery back-up,
Optical smoke alarms in circulation spaces - hallways & landings e.g. Ei146 or Ei166 with or without RadioLINK,
Heat alarm in the kitchen e.g. Ei144 or Ei164 with or without RadioLINK,
Smoke alarm or heat alarm as best suited for the particular circumstance (see page 4 for definitions and usage), in the main living room,
All alarms should be interconnected,
The sound pressure level of the alarm signal measured at the doorway of each bedroom with the door open should be at least 85dB(A)
Existing Tenanted Properties,
Two and three storey - Grade D, LD3,
Optical alarms in circulation spaces - hallways & landings e.g. Ei146 or Ei166 with or without RadioLINK.
If a fire risk assessment shows the property or occupier to be a high fire risk, increase the number of alarms installed to meet the risk - e.g. follow new build recommendations for an LD2 installation
All alarms should be interconnected,
The sound pressure level of the alarm signal measured at the doorway of each bedroom with the door open should be at least 85dB(A),
Single storey - Grade F, LD3,
Battery powered with a minimum battery life of 5 years e.g. Ei 10 year alarm
Optical smoke alarm in circulation spaces - hallway e.g. Ei3105TYCH.
If a fire risk assessment identifies a concern that the occupier cannot or may not replace a battery, use mains alarms or mains with battery back-up,
If a fire risk assessment shows the property or occupier to be a high fire risk, increase the number of alarms installed to meet the risk - e.g. follow new build recommendations for an LD2 installation,
System Grades and Categories
Six different grades of fire detection systems are defined and - generally speaking - the greater the fire risk the more comprehensive the system should be.
Briefly, the Grades are as follows:
GRADE A - A full system with control and indicating equipment installed to BS 5839: Part 1
GRADE B - Detectors and sounders using simpler specified equipment
GRADE C - Detectors and sounders or alarms with central control
GRADE D - Mains powered alarms with an integral stand-by power supply
GRADE E - Mains powered alarms with no stand-by power supply
GRADE F - Battery powered alarms
Three different categories of life protection systems are defined:
LD1 - Alarms in all circulation spaces that form part of escape routes and all areas where a fire might start, but not bathrooms, shower rooms or toilets
LD2 - Alarms in all circulation spaces that form part of escape routes and rooms or areas that present a high fire risk
LD3 - Alarms in circulation spaces that form part of escape routes\
The Code emphasises that no one type of alarm is most suitable for all
applications. Consideration must be given to the most suitable type of
detection - optical, ionisation and heat.
Wireman only installs Aico alarms. “Aico, offer high quality, high reliability mains-powered optical smoke alarms, ionisation smoke alarms and heat alarms. These are available with a choice of conventional battery or unbeatable 10 year plus Lithium cell back-up technology.
