A fire alarm system is a set of electric/electronic devices/equipment working together to detect and alert people through visual and audio appliances when smoke/fire is present. These alarms may be activated from smoke detectors, heat detectors, water flow sensors, which are automatic or from a manual fire alarm pull station.

Types of Fire Alarm System:
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.

Conventional Fire Alarm System
In a Conventional Fire Alarm System, a number of call points and detectors are wired to the Fire Alarm Control Panel in Zones. A Zone is a circuit and typically one would wire a circuit per floor or fire compartment. The Fire Alarm Control Panel has a number of Zone Lamps. The reason for having Zones is to give a rough idea as to where a fire has occurred. This is important for the fire brigade and of course for the building management. The accuracy of knowing where a fire has started is controlled by the number of Zones a Control Panel has and the number of circuits that have been wired within the building. The Control Panel is wired to a minimum of two sounder circuits which could contain bells, electronic sounders or other audible devices. Each circuit has an end of line device which is used for monitoring purposes.

Addressable Fire Alarm System
The detection principle of an Addressable System (Fire Alarm System) is similar to a Conventional System except that the Control Panel can determine exactly which detector or call point has initiated the alarm. The detection circuit is wired as a loop and multi devices may be connected to each loop. The detectors are essentially Conventional Detectors, with an address built in. The address in each detector is set by dil switches and the Control Panel is programmed to display the information required when that particular detector is operated. Additional Field Devices are available which may be wired to the loop for detection only i.e. it is possible to detect a normally open contact closing such as sprinkler flow switch, or a normally closed contact opening.

Fire Alarm System comes with single loop as well as multi loops. It depends on requirement. The items which are integrated with Fire Alarm Systems are given belowâ?¦.

Features:

Safety first: In the fire or power-off,the door can be free to promote and ensure unimpeded;

Various Interfaces:1/O,RS232/485,CAN interfaces,which it is convenient to control interface.

Two working modes:NC and NO,which is easy to deal with peak and normal use

Multiple control modes:There are unidirectional,bidirectional,free passage and authorization passage to meet fully the usersâ?? needs,which consist of nine control modes;

Precise positioning precise positioning by photoelectric sensors,the work cycle of door is regular and precise positioning to ensure correct position after long work;

Various status information:It provides operational status of each component,the prevalent status,abnormal status,etc.

Indicator control:the indicator is able to show three status of front and back indicator (allow through,no through,system maintenance),Also which show the passage direction and passage status (A to pass,B to pass,no through),According to reasonable indicator control,which is convenient for users to management.

Machine core control:the two sides machine core work with coordination and synchronization,and the control system provide convenient management functions,the passage controller can control the machine core of all functions and settings of all parameters,which is reasonable for consisting of the various components of the machine core operation flow,and which is more intelligent and safety to design a access control function;

Sensor Analysis:The sensor got signal which real-time processing and analyzing a person or object for a variety of action,according to the results of analysis are to accurately control the action of machine core,indicator and alarm etc.

Sound output:Whether it is normal or emergency situation,the sound output can remind passengers and administrators timely and friendly.witch cooperate with light and make the perfect effects.

Convenient settings: With the screen and buttons consist of human-machine interface,the users can quickly and easily query and set channel parameters,no longer totally dependent on the host computer or extremely unfriendly pure key board to query and set parameters.This is not necessary functions,but once experience we believed that no one will forget it is great.
