fire detection system

A fire alarm system warns people when smoke, fire, carbon monoxides, or other fire-related emergencies are detected. These alarms may be activated automatically from smoke detectors and heat detectors or may also be activated via manual fire alarm activation devices such as manual call points or pull stations.

Informed Systems is the leading wholesale reseller of Honeywell, Asenware, C-tec Fire , Morley, Fire Class, Zeta, Protec, Menvier Alarm Systems in Nairobi Kenya, and ISO 7240-14 certified which is an international standard for Design, installation, commissioning, and service of fire detection and fire alarm system in and around the building.

This standard was published in August 2013; Status, Published; Edition 1; Technical Committee ISO/TC 21/SC 3 Fire detection and Alarm system. Fire Alarm Detection and Alarm Systems are categorized into Conventional Fire Alarm Systems and Addressable Fire Alarm Systems.

Conventional Fire Alarm Systems

Conventional systems are hardware-based and use analog technology. Conventional fire alarm systems are made up of zones. Multiple devices, both initiating and notification devices, make up a zone which connect to the main control panel. Conventional systems are analog in that they use electrical currents to communicate with the control panel.

Initiating and notification devices are designed to dramatically increase the current in the circuit (the amount of electricity flowing through the wires) any time the environmental conditions (heat or smoke) in the area of the sensor exceed a predetermined threshold.

This change in the current is communicated to the control panel to trigger the alarm. Because a conventional system relies on individual circuits to communicate with the control panel, the information the panel can receive is limited to the number of devices it can support.

The information is also limited in the sense that it only tells the panel whether a device has been activated or removed, not which device or where.

Components of Conventional Fire Detection and Alarm Systems Includes; Fire Cables, Fire Alarm Control Panel (FACP), Heat and Smoke detectors, Manual Call Point (MCP), Sounders, and Sounder Beacon.

i. Addressable Fire Alarm Systems

An addressable fire alarm system is one in which all fire and smoke detection devices in a system are connected and communicate both with each other and a central control monitoring location.

This interconnectivity allows the control personnel to identify the location or “address” where the initial detection occurred. The information directs the emergency response team to pinpoint their efforts immediately to the precise location of the developing problem.

Direct identification of the site of the outbreak is beneficial for several reasons. Occupants can initiate immediate evacuation from the adjacent areas while others receive notification to evacuate in the opposite direction from that location to prevent crowding.

An additional advantage of an addressable fire alarm system is that elements can be programmed to respond in particular ways with specific responses. Systems can be programmed to create a “cause and effect” response. In large buildings with several stories, wings, or sections, it is possible to program alarms that are some distance away from the activated alarm to delay sounding to evacuate the building in orderly sequences.
False alarms cause interruptions in business activity and unnecessary emergency responses by local authorities. Sometimes accumulations of dust and grime can set off an alarm.

With addressable, connected alarm systems, each device is monitored from a central location. If dust accumulations begin to affect the atmosphere around the sensors, a warning is transmitted to the central control area. The location is noted, and the device can be serviced without the alarm ever sounding.

Components of Addressable Fire Detection and Alarm Systems Includes; Fire Cables, Addressable Fire Alarm Control Panel (FACP), Addressable Heat and Smoke detectors, Addressable Manual Call Point (MCP), Addressable Sounders, and Addressable Sounder Beacon.
