Q

What is cross-alarming ?

A

Cross-zone detection is all about the confirmation of a fire through requiring two fire detectors in the space to activate before beginning the releasing sequence. Cross-zoned detection is not always used to release a suppression system, but it often is when using smoke detectors

Q

What is a class X pathway ?

A

Class X pathways are essentially Class A pathways with isolation capability (short circuit protection) between each device

37
Q

What is a class B pathway ?

A

Class B is the most common type of pathway on fire alarm systems. A Class B pathway does have a redundant (return) pathway, so any equipment located on the circuit or pathway past a single open will not operate. Class B conventional circuits go through all devices and terminate in an end of line resistor (EOLR), which provides electrical supervision of the circuit. Class B signaling line circuits (addressable) do not have an EOLR but are supervised and annunciated by individual devices.

87
Q

What is an isolator?
