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 1)
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. Verify detector placement with Final AHJ.
SECTION C. ELECTRICAL CONNECTIONS - All models (Figure 4 - 4 wire operation, figure 4A - 2 wire operation)
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 can configure the unit for independent delay on alarm and power loss using four wires or
a single adjustable delay using only two wires. Use steps 1-2-3-4 for 4 wire operation. *Use 1-2-3 for 2 wire operation.
See Figure 4, page 3A for 4 wire dual delay wiring and Figure 4A, page 3B for 2 wire single delay wiring
1. Turn off power supply before beginning.
2. Verify voltage rating of release device to power source being utilized.
3. Connect 24 volt power source inputs to WPS circuit board, screws 1 & 2. On 24VDC units observe proper polarity by
placing positive (+) wire to screw 1. 120 VAC use TB3. 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 72-
1993 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: SS90-B-WPS only.
*Close Limit Detection (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. Fail-safe operation shall be maintained under all operating conditions.
