Fire Detection Systems

Fire Detection Systems
A fire alarm system has a 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 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. Alarms can be either motorized bells or wall mountable sounders or horns.
What is Fire Detection Systems?
Fire is one of the major calamities which has an uncanny ability to strike when it is lease expected and causes havoc if not detected and controlled at the inception stage. The loss caused by this catastrophe cannot be measured in monetary terms alone.
E-systems protects your premises from fire by using an intelligent early warning fire detection system. The system comprises of a Micro-controller based Fire Panel with a built in rechargeable battery up and has capability of being attached to the Auto-Speech Dialer. The system Uses Heat, ROR, Optical and ionization sensors to detect fire.
Fire Detection systems are following.
- Ionization, Model DH100ACDCI
- Air velocity rating from 500 to 4000 feet per minute
- Air velocity rating from 500 to 4000 feet per minute


- Temperature range, thermal models 32ºF to 100ºF (0ºC to 38ºC)
- Temperature range, all other models 32ºF to 120ºF (0ºC to 49ºC)
- 120/220 VAC or 24 VAC/DC
- Humidity Range 10% to 93% RH,
- 1 Form A alarm: 2A @ 30 VAC/DC
