1. What are the 3 kinds of fire detection systems?: 1. Detectors
2. Receivers
3 Indicators
Detectors talk to receivers, which talks to indicators.
Receivers and indicators are not typically found in homes.
2. What are 3 kinds of fire detectors?: 1. Smoke
2. Heat
3. Flame
3. What are 3 types of smoke detectors?: 1. Protoelectric Cell - Particles of smoke break a beam of
light
2. Ionization Chamber - Radioactive isotope reacts with smoke particles
3. Combination - photoelectric cell/ionization chamber
4. What are the 2 kinds of heat detectors?: 1. Fixed temperature: Temperature is at a predetermined
level.
- These are usually found in coolers or engine rooms where the temperature stays the same
2. Rate-of-Rise: measures a rapid increase in temperature
5. How does a flame detector work?: By detecting the flames UV light
6. What are 8 kinds of fire extinguishing agents?: 1. Water
2. Steam
3. Foam
4. CO2
5. Dry Chemical
6. Dry Powder
7. Halon
8. Wet chemical
7. What are the two kinds of dry chemicals?: Ordinary: Used to put out class B and C fires
Multi-purpose: Used to put out A, B, and C fires
