Q

Types of fire detection:

Used for incipient state.
– Have two chambers: reference and a measuring
– Small amount of radioactive material ionizes the air between the charge services in each chamber which results in current flow
– When combustion particles enter the detector, it impedes the flow which sets off an alarm
– Replaced every five years because radioactive material deteriorates
– Activities in paint booths, welding shops, areas with open flame, etc. The stuff in the air so wouldn’t work so well

A
