Can a heat detector be used in place of a smoke detector?
It is better to use a heat detector instead of a smoke detector when the area being monitored is not suited for a normal smoke detector. This includes areas where smoke may sometimes be present. Heat detectors are also used in dusty areas, where fine particles may trigger a smoke detector.
What is smoke and heat detector?
Smoke and heat detectors are sensors you will want to add to any system. These devices let a panel know if there is a fire in the building. An activated smoke and heat detector will cause an instant alarm. Your system will take action based on your monitoring plan.
Which comes first heat or smoke?
Heat detectors are used when the primary focus is building protection. If a smoke detector was hooked up to a sprinkler system it could trigger the water during a false alarm, and water damage your building. A smoke detectors’ mentality is to go into alarm at the first sign of smoke.
What are the two types of heat detectors?
There are two common types of heat detectors—fixed temperature and rate of rise. Both rely on the heat of a fire incident to activate the signal device.
What are three types of heat detectors?
There are two common types of heat detectors—fixed temperature and rate of rise….17.1. 3.1 Optical (Flame) Detectors
- Ultraviolet (UV);
- Single-frequency infrared (IR);
- Dual-frequency infrared (IR/IR);
- Ultraviolet/infrared—simple voting (UV/IR);
- Ultraviolet/infrared—ratio measurement (UV/IR);
At what temperature does a heat detector activation?
around 135 degrees
Typically, the preset temperature that triggers the alarm is around 135 degrees. High temperatures are a good indicator of fire (unless you have your heater set to 135 degrees). Both the rate-of-rise detectors and the fixed temperature detectors are great for sensing fires.
How does a heat detector work?
Heat detectors work on a similar principle used by smoke detectors, by tracking the temperature instead of smoke. Heat detectors generally detect the heat that comes as a result of combustion. The devices trigger an alarm when they sense a rapid rise in temperature or when a certain temperature is reached.
What are different types of smoke detectors?
There are two types of smoke alarms in general use for home smoke alarms: photoelectric and ionization. These smoke alarms sense the presence of smoke differently. The type of smoke produced by a fire depends on the type of fire. Flaming fires produce a different type of smoke than smoldering fires.
What is the use of smoke detector?
smoke detector, device used to warn occupants of a building of the presence of a fire before it reaches a rapidly spreading stage and inhibits escape or attempts to extinguish it.
