zoned/annunciated alarm

Which type of supervising station alarm system is connected to a municipal fire alarm system?

auxiliary alarm system

which is an advantage associated with using a nondedicated smoke control system?

less chance of component failure due to regular sue and maintenance

How does the exhaust method control smoke?

uses mechanical ventilation and the properties of smoke to collect smoke at the highest point in a large space

Which heat detector uses TWO metals, one which expands faster than the other when heated, to break a circuit and send a signal to the fire alarm control panel?

bimetallic detector

Where is the opposed air flow method of smoke control typically used?

large spaces where smoke migration is limited by opposed air flow, such as subway and railroad tunnels

In which type of standpipe system is water admitted to the system when a hose valve is opened?

an automatic dry system

Which type of smoke control system or method uses mechanical ventilation along with the properties of smoke to collect smoke at the highest point in a large space?

exhaust

Which type of sprinkler system uses pressurized air or nitrogen in place of water in the sprinklers above a valve?

dry-pipe system

Which type of standpipe system contains water only when water is supplied through the FDC?

True or False: in many cases, the water supply for sprinkler systems is designed to supply only a portion of the sprinklers installed in the system.

true

which RATE-OF-RISE detector uses self-contained PNEUMATIC sensors to monitor SPECIFIC locations?

pneumatic rate-of-rise spot detector

Which activation method will trigger fixed-temperature heat detectors?

melting of heated material

Which type of photoelectric smoke dtector focuses a beam of light across the monitored area into a cell and initiates an alarm when the beam is obscured?

projected-beam smoke detector

Who monitors a central station alarm system?
