CONVENTIONAL FIRE PANELS
Conventional fire alarm systems: This is the usual choice for very small systems or where budget constraints apply. Conventional systems have been around for many years, and are a well-proven, dependable technology.
All the intelligence resides within the control panel. Detectors and break glass units are connected together on a single run of cable for each zone or area. When the panel detects a resistance change, through activation of a detector or call point, a zone latches into fire and the sounders or bells are triggered.

Conventional fire alarms
Conventional fire alarm systems are wired in zones. Each zone would have devices wired in series and have a end of line resistor at the end of each circuit . Should a fault if fire be detected it changes the resistance and triggers the fire alarm panel at that zone. Conventional fire alarm systems are used in small commercial stores or small apartment complexes .
ADDRESSABLE FIRE PANELS
Analogue addressable fire alarm systems: These are advanced, flexible, reliable detection systems. Exact fire location is determined immediately as each individual detector has a unique address to show its exact position. False alarms are reduced, and real alarms detected sooner by advanced filtering techniques on individual detectors. Zoning is done on a software level and therefore is independent of cable paths.
Addressable fire alarms most used in Ireland are Morley Ias ,Advanced ,Aritech, Menvier , Siemans, Autotronica, Juno, Ctec.
Addressable fire alarm systems are designed for multiple occupancy residential properties and large commercial and industrial premises.fire alarm cabling is wired as a loop or multiple loops depending on size of property .repeater fire alarm control panels can be situated in different locations in large properties or fire alarm panels can be networked also.In addressable fire alarm systems devices will each have its own individual coded address. When the fire alarm system control panel receives a signal from an either a optical smoke detector or a heat detector or manual call point ,it can see where exactly the detection device is .
It will display this information on the front of the fire alarm panel with the correct location text. All detection devices can have its sensitivity levels checked from the front of the fire alarm system.additional devices can be connected to addressable fire alarms systems such as an io device .this can connect any device to the system or a adjoining fire panel .Io modules can trigger an Aov system or an intruder alarm for monitoring purposes and water detection or pa system can be connected to addressable fire alarm systems via Io interface .
