A proposal of low cost central monitoring alarm system at Ibu Pejabat Mardi Serdang, Selangor Darul Ehsan / Muhamad Zainon

The purpose of this project is to design a central monitoring alarm system for fire fighting alarm system and cold room alarm system. There are more than 36 numbers of automatic local fire alarm system which are controlled separately at each building and generally comprises of fire detection alarm system, smoke detector alarm, halon gas detector alarm, break glass alarm, fire fighting diesel pump alarm, and battery fail alarm. All these will operate if a sensor or detector of any zone detects a hazard, that particular zone's Alarm will flash and bell rings. Alarm light will keep on flashing and bell continue ringing if the hazard and the halon panel is not attended to. In this design all the alarms are to be centralised and monitored at MARDI Training Center which is 500 meters away from MARDI Head Quarters. Multiplexer / Demultiplexer and others related circuits are used in this design for a long distance data transmission.
