U.L. LISTED CANADIAN LISTED CSFM: 7300-1418:100

GENERAL DESCRIPTION: S/N:__________________

The "WPS" World Power Series, Time Delay Release Devices are designed for use on rolling doors, single-slide and center
parting level and inclined track doors. All models are normally ener gized Fail-Safe Releasing Devices incorporating state of the
art electronic control circuitry. The Release Devices respond to emergency conditions generated by manual or automatic
normally closed initiating devices and shall be used in conjunction with a temperature fuse link system.

This Release Device *features include; world power source capability allowing the same unit to be used on 24VDC, 24V AC or
120VAC 50 or 60HZ., separate adjustable time delays for alarm and power loss, motor voltage sensing, form-C relay output,
proximity/door edge input and trouble diagnostic capabilities. Models A and B can be wired for two or four wir e configuration.

*Check model label on unit to be installed to verify applicable features.

CAUTION: Review all installation instructions, procedures, cautions and warnings contained within this manual prior to
installing and/or servicing this product. As with all r eleasing device systems, maximum fire protection is provided when
installed in accordance with factory specifications and used with fuse link systems.

Fail-safe operation can only be provided with input power applied. DO NOT install this unit without fuse links.

TEST SYSTEM AT LEAST ONCE EVER Y 90 DA YS TO ASSURE PROPER OPERA TION.

Installation and testing to factory specifications shall be performed by factory authorized personnel for proper operation in
accordance with all of the latest National Fire Protection Association (NFPA), Underwriters Laboratories (UL), National
Electrical Code (NEC), local, state, county, district and/or other applicable building and fire standards, guidelines,
regulations and codes including, but not limited to, all appendices and amendments and the requirements of the local
authority having jurisdiction (AHJ).

INST ALLA TION INSTRUCTIONS - T o 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 NFP A 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. V erify 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 NFP A 72­1993 and NFP A 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: LM90-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.

TROUBLE RELA Y (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. W ith power applied TB1-9&10 are closed and toggle in alarm and
power loss.

Optional wiring - Verify that all operating voltage is off before continuing.

5. 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.

6. Trouble Relay - Connect wiring to common TB1-9 and either N/O contact TB1-10 or N/C contact TB1-8.

* Note: Electrical loop must be provided as dry contacts and may not be used in conjunction with the simulta-
neous 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 LEA VE COVER OPEN AFTER CONNECTIONS ARE MADE!
