arranged to perform this function if specifically designed to
operate the local energy type Master Box.
1. All wires shall be installed in accordance with the National Electrical Code.
2. Auxiliary circuit wires must be installed in rigid conduit.
Three-Fold Fire Alarm Boxes
All of the working parts are mounted in an *inner case
which is installed in the familiar “Signal Red” weatherproof
cottage shell. Both the inner and outer cases are con-
structed of aluminum, suitably treated and finished, the
outer case is painted red and the inner case is white. A
white guard panel is installed on the outer door to protect
and highlight the starting lever. Both narrow sides of the
box have a Scotchlite™ reflective “FIRE” sign that appears
in red letters with a white background. The outer case is
provided with a threaded 1/2”, (typical 2 places) conduit
connection at the top and a clearance hole for 1/2”, (typical
2 places) conduit at the bottom.
*The inner case is not included with Modified Boxes.
Scotchlite™ is a trademark of 3M™.

Figure 1 Typical Wiring Connections - Gamewell-FCI Master Fire Alarm Box
For Shunt Type Master Box
1. Connect initiating devices in series with auxiliary circuit.
Devices must be normally closed and must open on
alarm.
2. Auxiliary circuit loop resistance must not exceed
30 ohms.
3. Supply voltage of the circuit in which the Master Box
is connected should not be less than 30 volts.
Industrial Master Transmitter
This transmitter utilizes the standard Three-Fold Mecha-
nism and auxiliary tripping attachment mounted in a sheet
metal enclosure with a locked, hinged door. The box code
number plate is mounted on the outside of the door. The
transmitter dimensions are: 12” high x 12” wide x 6” deep
(30.48 H x 30.48 W x 15.2 D cm).
This unit is designed for sur-
face mounting.
For Local Energy Type Master Box
1. Auxiliary circuit normal operating (alarm) current should
be.250 amperes DC or .380 ampere 60 Hz AC.
2. Auxiliary circuit supervisory current should be not more
than .050 ampere DC or .070 ampere 60 Hz AC.
3. Nominal volts across coil = 3.65 VDC or 50 VAC 60 Hz.
Use series resistor for higher voltages.
4. Maximum safe current in trip coil 125% of nominal
values given.
5. Coil, wiring, and terminals insulated for 125 VAC
(1250 VAC breakdown test).
Installation Information
Although the Gamewell-FCI Master Fire Alarm Box is
designed for connection to auxiliary systems inside the
buildings, the National Fire Protection Association recom-
mends that the Master Box be placed outside of, but con-
venient to, the building protected. Installation on a pole or
wall nearby, preferable using a mounting bracket, reduces
the fire hazard to the circuit wires of the main fire alarm
system. It is recommended that the lead-in wires from the
main circuit to the Master Box be placed underground, but
if aerial wire construction is used, adequate lightning pro-
tection should be provided at the Master Box. A Gamewell-
FCI, GW 44551-01 lightning arrester is suitable for this pur-
pose. Three (3) conductors, of #14 or #16 AWG wire, are
recommended for connection between the Master Box and
the Reset Supervisory Panel. This panel may be installed
inside the building, preferably in some location where it will
be visible a major portion of the time to certain of the build-
ing personnel. This applies to the shunt trip type Master
Box. Where the local energy type is used, requiring local
power source for auxiliary operation, the supervisory panel
may not be necessary as interior system control panels are
