INSTALLATION INSTRUCTIONS - To be performed by factory authorized personnel only.
The following installation procedures must be followed to assure performance of the release device to factory standards.
SECTION A. MOUNTING PROCEDURE (Figure 3)
1. The release device shall be mounted on a vertical surface with chain end link exiting side of enclosure as illustrated in
figure 3. The unit may be rotated 90 degrees CW for a direct vertical pull.
2. Release device enclosure shall be mounted with minimum #10 size fastening screws or bolts for securing to structures
other than masonry. Masonry applications shall utilize 1/4" or greater anchors or studs as required to insure proper
mounting strength.
3. Release device and associated hardware [sash chain or 1/16 cable, eyebolts, fuse links (DO NOT install this unit
without fuse links), turnbuckles] shall be installed as per door manufacturers recommendations (figure 3 typical
installation configuration). Note should be taken that the end link direction of pull is perpendicular to the enclosure
side. An eyebolt installed at a distance of 18 to 24 inches from the release device should adequately redirect sash chain
pull as illustrated in figure 3.
4.Complete hardware installation by connecting fuse links, sash chain, S-hooks and turnbuckles as required. Push reset
lever in direction of arrow on label to allow insertion of end link through
release device side opening. Push end link
completely in and release reset lever to latch end link. Remove sash chain slack by adjusting turnbuckle.
Do Not exceed 40 lbs. maximum pull rating on release device.
SECTION B. Smoke Detectors.
When installing smoke detectors with this unit refer to NFPA 72-1993 and NFPA 80, for instructions concerning proper
placement and detection coverage. End of line devices (relays) must be installed in accordance with U.L. 864. See
electrical connections figure 4.
SECTION C. ELECTRICAL CONNECTIONS - All models (Figure 4)
Installation of all wiring and connections shall be performed in accordance with, but not limited to, the latest NFPA,
U.L. and N.E.C. standards. In addition, all installations subject to Canadian standards shall be performed in accordance
with the Canadian Electrical Code, Part I, with respect to wiring material, wiring gauge related to power capacity
requirements and circuit length and wiring methods.
The following wiring instructions will configure the unit for independent delay on alarm and power loss. Four wires, two
for input power and two for the initiating loop, are required. When installing this unit where only two wires are available,
call tech support. This unit can accommodate a two wire installation.
1. Turn off power supply before beginning.
2. Verify voltage rating of release device to power source being utilized.
3. Connect power source inputs to TB3, screws 1 & 2. On 24vdc units observe proper polarity by placing positive (+) wire
to screw 1. TB3 screw 3 shall be utilized for earth ground where applicable.
4. Normally closed initiating devices (smoke detectors)- remove jumper from screws 1 & 2 (Alarm loop will not function
if jumper is not removed). Connect wiring from N/C initiating device alarm loop to TB1 screws 1 & 2 (see NFPA 721993 and NFPA 80 for proper placement of smoke detectors). NOTE: Alarm loops cannot be series or parallel
connected between TB1 of multiple release devices. Contact tech support for wiring instructions where multiple doors
must close from a single initiating device.
OPTIONS: FIREFLY II-B-X only.
Motor voltage sensing - This option is used to detect the presence of operating voltage on motor driven units where
closings are automated by a fire alarm signaling source in conjunction with the operator. When motor control secondary
voltage is present (24V-30V AC or dc) the release device logic will prevent the solenoid from energizing on alarm, thereby
allowing the motor to drive the door closed by activation from the automated fire alarm signaling source through the operator.
CAUTION: The automated signaling source and/or the motor operator shall contain logic capable of determining whether
the door has fully closed upon activation. In absence of full closure, the motor control voltage shall be interrupted to release
device allowing for release device initiated closure. CAUTION: DO NOT use this option on non-automated installations
where door closings through the motor can only be initiated manually

*DOOR EDGE (Lower limit/Proximity switch) -This option interfaces to electrical contact type lower limit sensing devices
and/or magnetic proximity type switches. If the electrical contact has toggled states from its N/O condition to a closed
condition (TB1-5&6) indicating the door edge has made contact with desired down position, the release device logic will
prevent the solenoid from energizing on alarm, thereby eliminating any damage which may result to the door from the release
device attempting to close the already lowered door. This option only works as long as power is available to unit.
TROUBLE RELAY (TB1-8,9&10) The trouble relay toggles immediately upon a power loss or alarm condition and may be used
for turning on signalling appliances (horns,strobes,etc.) or other external signalling functions requiring a dry contact open or
closure. Figure 4 illustrates contacts with no power to unit. With power applied TB1-9&10 are closed and toggle in alarm and
power loss.
Verify that motor voltage is off before continuing.
5. Connect motor control sensing voltage (24vac) from motor controller transformer secondary to TB2 screws 1 & 2.
6. Normally open lower limit/proximity switch (closes in down limit). Connect wiring from *Aux. electrical loop to
TB1 screws 5 & 6. Leave jumper in TB1-6&7. Remove jumper & use TB1-6&7 for a N/C which opens in down limit.
* Note: Electrical loop must be provided as dry contacts and may not be used in conjunction with the simultaneous switching of a motor control or any other voltage through the same contacts. Connections of this type will
result in immediate damage to the release device.
Verify all connections made within unit. Close hinged cover and secure screw on lid after all connections are made.
DO NOT LEAVE COVER OPEN AFTER CONNECTIONS ARE MADE!
