PD. Dian Karya Sells Fire Alarm System, There are three fire alarm systems that we usually know, namely:
Conventional Fire Alarm System
This system uses two cable contents for all types of detectors. The cable used is generally a NYM 2x1.5mm power cable or 2x1.5mm NYMHY (unless stated otherwise by the consultant). In installations that are quite critical, fireproof cables are often used (FRC = Fire Resistance Cable) with various sizes, for example 2x0.75mm or 2x1.5mm, especially for cables that lead to a fire alarm panel or to a 220V power source. Therefore, generally using two cable contents, then the conventional fire alarm is also known as the 2-wire term.
Addressable Fire Alarm System
Is a system consisting of fire detectors and devices that are connected back to the central control panel. With an addressable system, each device has an address or location, allowing triggered detectors to be identified quickly and precisely. This system is suitable for large buildings, especially commercial places.
Semi-Addressable Fire Alarm System
This system is considered more effective when compared to conventional systems because it is closer to finding out where the fire zone actually occurs. This system is the formation of a conventional system into an addressable system using the control module. The method is to connect a conventional system with a control module and then connect to the zone that has detectors.
