1.0 INTRODUCTION
The
Model CP-48 Control Panel is a single zone fire alarm
control unit, which may employ the specified ionization, thermal or
photoelectric type detector. This unit has been especially designed to
operate from a 48 volt DC power input source such as is available in
telephone community dial offices. The front cover contains a manual
fire alarm station and entry key lock. Displayed through the front cover
are the; Power On, Alarm, and Trouble Visual Indicators. Within
the control panel are a fire alarm Reset/Lamp Test switch, a switch to
silence the panel contained audible alarm, two sets of isolated alarm
relay contacts, and one set of trouble relay contacts.
2.0 USER OPERATING INSTRUCTIONS FOR CP-48
(Refer to schematic on inside back cover.)
2.1 Normal Stand-By Operation:
With panel connected to the 48 VDC Power Supply using the correct
polarity connection, and the initiating circuit terminated with the 1.8K
end of line resistor, the panel should display a normal condition with
only the visual Power indicator illuminated in the normal state.
An off normal position of the internal audible alarm selector switch
when the panel is not in alarm condition will result in a trouble
condition.
An alarm condition may be cleared or reset by operating the momen-
tary Reset switch. The associated manual fire alarm station must
be returned to manual position before the system will reset.
2.2 If Fire Alarm Sounds:
a.
Notify the Fire Department. If the system is connected to the Fire
Department or a central station, this is done automatically by the
control equipment. Keep in mind that the Fire Department or
central station should be notified when resetting the system.
b.
If fire is not apparent, DO NOT RESET SYSTEM. Locate the
detector initiating the alarm. The initiating detector will have the
base indicating lamp energized.
c.
After the fire is completely extinguished and all smoke and gases
are cleared from the area, reset the system by moving the Reset
Switch momentarily to the Reset position.
2.3 When Trouble Condition Develops:
a.
The trouble contacts will be in trouble state. Call your author-
ized Siemens Building Technologies, Inc. Representative. The
trouble should be diagnosed and corrected immediately.
2.4 Periodically Testing the System
:
(Be sure to notify the
proper authorities prior to performing tests
)
a.
The system should be tested at regular intervals to insure
operational reliability and optimum performance. To test the
system, activate at least one detector. An lonization detector may
be activated by blowing smoke into the screened chamber or
holding a lighted match a few inches below it. Check that system
responds properly.
b.
Reset the system.
c.
This inspection should include checking the sensitivity of
every ionization detector using a sensitivity checker.
