CS-2261 Rev. A1 page 2 of 4 www.gamewell-fci.com Industrial Three-Fold Master Transmitter Master transmitters have provisions for electrical actuation but do not have any means for manual operation. They would be used when manual operation is not required such as an un-manned warehouse. Three-Fold Features All fire alarm boxes and transmitters incorporate the unequaled Gamewell-FCI Three-Fold spring-driven move- ment. This movement operates on positive non-interfering, quick succession and also features the unique three-fold automatic grounding capability. The movement is designed so that should two (2) boxes on a normal line be operated simultaneously, one will be auto- matically selected to transmit a correct signal for four com- plete rounds. If a box is operated while another box is in operation, it will not interfere in any way with the transmis- sion of the signal of the first box. The second box will take control of the circuit and transmit its complete four (4) rounds of signal upon the beginning of its next round fol- lowing the completion of the signal of the first box. This operation, without loss of alarm or interference between simultaneously actuated movements, is possible because of the positive non-interference and quick succession fea- tures. The self-grounding mode of operation is accomplished automatically whenever a three-fold movement is actuated on a circuit which has developed an open. In this mode of operation, signals may be received from transmitters and boxes by properly conditioned receiving circuits at head- quarters. The Gamewell-FCI Three-Fold Boxes and Transmitters are capable of making approximately 26 attempts to command a circuit. If, at the end of that time an actuated unit is still unable to get a clear line, it will automatically “take over” (bulldog) the circuit to transmit four (4) rounds of its signal before it is wound down. The mechanism is capable of transmitting signals at varying rates of speed ranging from electrical impulses at 3.25 second intervals to .25 second intervals and has provisions for adjusting speeds within this range. When the main spring is run-down so there is insufficient capacity left for transmission of four (4) complete rounds of the signal, the mechanism is locked to prevent further operation until the spring is rewound, to prevent transmis- sion of a fragment of a signal or stopping of the mechanism in a position which might hold the circuit open. If the main spring is run-down, the circuit will be grounded. Thus, by the testing means provided at headquarters, the location of the faulty box may be determined. Operation Manual Pull The manual Three-Fold Boxes and Three-Fold Master Boxes are provided with means for manual actuation. These boxes are of the quick action type and require only the opening of the quick action pull down guard and the depressing of the lever to trip the mechanism. Once tripped, no further manipulation of the lever has any effect on the mechanism. When the box is operated in a normal metallic circuit, four (4) rounds of the box number will be transmitted to headquarters. If another box has control of the line, the box operated will wait until the line is clear and then transmit its signal to headquarters. Test Features In addition to transmitting emergency signals for fire alarm purposes, the fire box is equipped with a telegraph key so that authorized persons may transmit manually formulated code signals and receive audible indication, via tap bell, of the transmission of all code signals on the circuit. The test block is provided so that all functions of the box can be tested without the transmission of any signal over the circuit and without impairing the transmission over the circuit of signals from other sources. Means for cutting the box out of service or grounding either side of the circuit as required are also provided. Frequently, the many advantages of the Three-Fold opera- tion are desired without all of the other features of a stan- dard Gamewell-FCI Fire Alarm Box. Accordingly, we offer the MODIFIED version of the standard units. It is basically the same as the popular Three-Fold Box which has had an excellent service record for decades. The difference is that the MODIFIED Three-Fold Boxes do not have the inner case, tap bell, telegraph key and test block. Construction Signaling Mechanism The signaling mechanism is carefully assembled with all parts precision-manufactured. All parts are plated or treated to resist rust and corrosion, and the mechanism is completely enclosed in a dust tight transparent plastic

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™. 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. 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 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. Figure 1 Typical Wiring Connections - Gamewell-FCI Master Fire Alarm Box Figure 2 Dimension Data for Master Boxes 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. 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).
