consisting of _______. - ✔✔Rechargeable batteries
✔✔May an audible trouble signal be permitted to be common to several supervised
circuits? - ✔✔Yes!

runner shall establish two way communications with the station at intervals not
exceeding ________ minutes. - ✔✔15
✔✔Automatic alarm initiating systems equipped with alarm verification features shall be
permitted provided (4) _____. - ✔✔1- Alarm verification feature in not initially enabled
unless conditions or occupant activities are expected that cause nuisance alarms.
2- A smoke detector that is continuously subjected to smoke concentration above alarm
threshold does not delay system functions more than 1 minute.
3-Actuation of an alarm device other than smoke detector causes the system functions
without additional delay. (not 10 seconds)
4-Current status of the alarm verification feature is shown on the record of completion.

signals are transmitted over the same circuit, provision shall be made to either obtain
(2) ______ of the fire alarm signal, to prevent the loss of an alarm signal. - ✔✔Sufficient
repetition
Alarm signal precedence

supervisory services for household fire warning systems, whose components may be
used in whole or in part in common with a non-fire signaling system. - ✔✔Combination
system
✔✔A means for turning off an activated alarm notification appliance shall be permitted
only if _________. - ✔✔The means must deactivate both the audible and visible
notification appliances simultaneously.

high humidity
dusty conditions
hazardous locations
✔✔When common wiring is employed for ________ the equipment for other than fire
alarm signaling system use shall be connected to the common wiring of the system in
such a manner that short circuits, or open circuits, or grounds in this equipment or
between this equipment and the fire alarm system wiring, will not interfere with either
the supervision of the fire system or prevent alarm or supervisory signal transmission. -
✔✔Combination system.
✔✔A pressure tank supervisory signal initiating device for a pressure tank shall detect
both high and low pressure conditions. A signal shall be obtained when the pressure is
increased or decreased ______ psi from the required pressured value. - ✔✔10
✔✔Homeowners shall test systems in accordance with the manufacturer's instructions
and shall have every residential fire alarm system tested by a qualified service
technician at least every _____. - ✔✔3 years
✔✔Manually actuated alarm-initiating devices shall (3) _____. - ✔✔1. Be used only for
FA initiating purposes and guards tour signaling.
2. Have the operable part of the manual FA box mounted between 3 1/2 and 4 1/2
above floor level.
