Three-Fold Fire Alarm Boxes

and Transmitters

Description

Gamewell-FCI coded fire alarm boxes and industrial trans-

mitters provide large industries, institutions and communi-

ties with the surest and safest means of prompt, effective

fire alarm reporting. They are positive and bring help

directly to the exact location from which the alarm was

sent. They minimize human error in fire reporting. There is

no confusion on the part of either sender or receiver; no

hazardous, time-consuming confusion between streets,

roads and avenues with the same or similar names.

The three-fold fire alarm boxes and transmitters are

designed for coded alarm reporting into a normally closed

series metallic signaling circuit having a normal DC flow of

0.100 amp. They transmit signals over this circuit in accor-

dance with their respective code numbers.

These three-fold assemblies are available in numerous

variations which can be classified into three major catego-

ries as follows:

Three-Fold Fire Alarm Box

Features

Three-Fold Manual Fire Alarm Box

Strictly manually operated by moving the pull guard forward

which exposes the operating lever. Downward pressure on

this lever actuates the code signal mechanism.

•

Manual activation.

Remote electrical activation.

Manual or remote activation.

Positive non-interfering movement.

Automatic grounding.

Three-Fold Master Fire Alarm Box

Red or blue.

Master fire alarm boxes have provisions for electrical actu-

ation in addition to the manual operation. They are

designed to provide the connecting link between a principal

municipal or industrial fire alarm system and auxiliary type

fire alarm systems installed for protection of public build-

ings, schools, industrial plants etc. With such provisions,

any alarm originating from heat detectors, smoke detec-

tors, sprinkler heads, etc. are automatically transmitted

through the Three-Fold Master Fire Alarm Box to the cen-

tral headquarters.

Local energy transmission.

Surface or semi-flush mount.

sion of a fragment of a signal or stopping of the mechanism

in a position which might hold the circuit open.

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.

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

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 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.

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.

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.

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.

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.

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.

Construction

Signaling Mechanism

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-

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

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.

3. Supply voltage of the circuit in which the Master Box

is connected should not be less than 30 volts.

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
