addressable fire alarm system definition
Also known as Security. This LED can only activate if there is a secondary device hooked into the Priority 2 Alarm terminals. This secondary device could be a security system, building management system, or another fire alarm control panel. Depending on how the panel is programmed, the panel's alarms may or may not activate when a condition like this is present. MS-2. MS-2 is a two zone conventional fire alarm control panel compatible with the new I3 smoke detectors from System Sensor, and provides such advanced features as drift compensation, maintenance alert, and freeze warning. MS-5UD. MS-5UD-3 is a five zone conventional fire control panel has features normally found in more expensive addressable systems. The MS-5UD-3 is fully programmable via built-in keypad and 80 character LCD display, so you do not need an external programmer. A fire alarm system can vary dramatically in both price and complexity, from a single panel with a detector and sounder in a small commercial property to an addressable fire alarm system in a multi-occupancy building. Addressable fire alarm systems allow a single pair of wires to be used to connect up to 200 devices, which provides cost savings in the wiring of large systems. The price of Addressable system is slightly higher than the conventional non-addressable system. MS-4. MS-4 is a four zone conventional fire alarm control panel compatible with the new I3 smoke detectors from System Sensor, and provides such advanced features as drift compensation, maintenance alert, and freeze warning. A fire alarm notification appliance that is used in the United States, the (Wheelock MT-24-LSM) with a strobe light. A fire alarm system is number of devices working together to detect and warn people through visual and audio appliances when smoke, fire, carbon monoxide or other emergencies are present. These alarms may be activated from smoke detectors, and heat detectors. Addressable Fire Alarm Control Panel employ one or more Signaling Line Circuits-usually referred to as loop s or SLC loop s-ranging between one and thirty. Depending on the protocol used, a Signaling Line Circuit can monitor and control several hundred devices. The panel receives information from environmental sensors designed to detect changes associated with fire, monitors their operational integrity and provides for automatic control of equipment, and transmission of information necessary to prepare the facility for fire based on a predetermined sequence. An addressable system is much more advanced than the non-addressable system. The addressable system has a higher degree of programming flexibility and single-point detection. Addressable fire alarm systems provide all the functions provided by the non-addressable conventional systems. The addressable system allows installation of more devices, providing greater coverage.
It allow a single pair of wires to be used to connect up to 200 devices, which provides cost savings in the wiring of large systems.
