ANSWER-Not less than 300 volts
Shall the voltage rating marked on P.F.L.A cables? - CORRECT
ANSWER-No, because they may be mistakenly used for electrical
applications.
What is 'Rate Compensation Detector'? - CORRECT ANSWER-A
device that responds when a temperature rises at an exceeding
rate that is predetermined.
What is a 'Smoke Detector'? - CORRECT ANSWER-a device that
detects both visible and invisible combustion particles?
Which detector is best a detecting invisible particles? - CORRECT
ANSWER-Ionization
Which sensor is better at detecting thick, visible smoke
particles? - CORRECT ANSWER-Photoelectric
