What is Fire Alarm System in short ?

Fire Alarm System
Fire alarm systems have been specially designed to alert people about fire at the earliest. From single to multi zone i.e. in a building (single) or in different floors of the building (multi-zone). These can also be installed in drawing rooms, bed rooms etc.There are basically three types of fire alarm systems, the functional advantage being that the source of fire is immediately detected and isolated which enables immediate corrective action.

STANDARD FIRE ALARM SYSTEM
These are designed to meet the fire requirements in the buildings, with LCD Display in conventional panel as a latest Technology.

ANALOGUE FIRE ALARM SYSTEM
These are also microprocessor based systems which work on the principle of extended loops and are suitable for large premises. The system gives LED indications in the control panel thereby isolating the source of fire.

ADDRESSABLE FIRE ALARM SYSTEM
These systems give LCD displays which show the exact location of all the detectors room-wise (for example computer room, drawing room etc.) from where fire has started.

SMOKE DETECTORS
lonisation smoke detectors: These help in the fast detection of both visible and invisible smoke particles in the range of 0.01 mm to 1 mm.
Optical smoke detectors: It provides early warning of a fire condition and is particularly effective in case of slow burning fires such as bedding, foam and plastics. This micro-processor system is suitable for small & medium size premises as it enables to isolate the source of fire, immediately.
HEAT DETECTORS
Heat detectors may be "fixed temperature type (which respond to temperature) or the "rate of rise" type (which respond to sudden increase of heat).
SMOKE AND HEAT BEAM WITH LOW LEVEL INDICATOR
These instruments are used to find the level of fire or smoke in a particular area. They can cover greater area and are suitable for high ceilings such as conference, cinema halls etc.
MANUAL CALL POINT & RESPONSE INDICATORS
Manual call point are earlier forms of fire alarm systems with the message " In case of fire break glass".Response indicators identify the source of fire in a room/false ceiling through LED display, enabling corrective action.
SOUNDERS OR FLASHERS
These are extremely useful in the night where there is no natural light. Sounders emit piercing alarm like sound from the place of fire and flashers get working to indicate the source of fire.

    These Lock Systems Replacement Parts the traditional keys with better and more secure automation features like remote locking and unlocking. In these locks, a latch or bolt is made to cross the opening between the side of the door and the doorframe, thereby preventing access. Digital Door Locks, also known as keyless doors, the locks replace the keys with a digital screen, where you can put numeric digits as a code.
