24 volt DC, closed circuit, and electrically super-
vised system. The system shall include, but not be
limited to, all control panels, power supplies,
initiating devices, audible and visual alarm
devices, and all accessories required to provide a
complete operating system. The system shall operate
as a continuous -sounding system which will sound all
audible and visual devices until it is manually
silenced or reset.

accessories necessary to the proper operation of the
system. All equipment shall be of the same company
unless documentation is provided to show
compatibility.
4. All equipment, devices, etc., shall be listed by
Underwriters Laboratories and/or Factory Mutual and
shall be approved for the purpose for which they are
intended.
5. The system shall comply with all national, state,
and city codes. The systems shall be approved by
the Fire Department prior to installation.
6. The system shall comply with the following provi-
sions of the current N.F.P.A. Standards:
a. N.F.P.A. 72A, B, C or D, whichever is
applicable.
b. N.F.P.A. 72E
c. N.F.P.A. 90A
d. N.F.P.A. 101 Life Safety Code
7. All local alarm systems being installed shall be
capable of being upgraded to a fully supervised
system and be listed by Underwriters Laboratories
and/or Factory Mutual for such use.
8. All alarm signals shall be automatically "locked in"
at the control panel until the operated device is
returned to its normal condition, and the control
panel is manually reset.
9. The operation of a manual station or automatic
activation of any smoke, or heat detector shall
cause:
a. All evacuation horns or bells to sound and lamps
to flash continuously.
b. Indicate on the control panel that the zone is
in alarm until the operated device is returned
to normal and the control panel is manually
reset except that the alarms may be silenced as
described elsewhere in these specifications.

a. The waterflow indication shall be isolated to
the last zone of the fire alarm panel.
b. The installation shall be in conformance with
Underwriters Laboratories Standard No. 864 which
states that the silence switch in the alarm
panel shall be bypassed on the zone that has a
waterflow detector. The only way that the alarm
may be silenced is by the waterflow switch
returning to normal after the water has stopped
flowing.
Power Requirements.
1. Power shall be obtained from a 120 volt AC power
supply. AC power shall be taken from a house panel
and shall have a separate overcurrent protector
provided. The house panel shall be in an area that
is protected from unauthorized entry.
2. Battery back-up is required on any fire alarm
installation. On a local alarm system there shall
be enough battery capacity to run the alarm system
in standby for twenty-four hours and after that
time, sound all alerting devices for at least five
minutes.
On a supervised alarm system there shall be enough
battery capacity to run the alarm system in standby
for sixty hours, and after that time, sound all
alerting devices for at least five minutes.
Panel Requirements. A fire alarm panel shall be
equipped with the following features:
1. A green L.E.D. shall normally be on, indicating that
the system is receiving normal 120 volt AC power. A
failure of normal power shall cause the L.E.D. to go
out.
2. Rechargeable batteries with automatic high -low rate
charger to maintain standby batteries in fully
charged condition. There shall be a low/no battery
trouble indicator that shall also operate the
general trouble devices as specified herein but
shall not cause an alarm to be sounded.
3. A power transfer circuit that will switch to standby
power automatically and instantaneoulsy if normal
power fails.
4. A trouble L.E.D. and sonalert, operating together,
shall signal any trouble condition. Failure of
normal power, opens, short on the indicating
QcIM
circuit, disarrangements in system wiring, or
grounds shall cause the trouble L.E.D. to light and
sonalert to sound. A silencing switch shall be
provided to silence the sonalert which shall be so
arranged that the trouble L.E.D. will remain lighted
until the system is restored to normal. When the
system is restored to normal, the sonalert shall
resound to remind service personnel to return the
silence switch to the normal position.
