The Release Device features include separate adjustable time delays for alarm and power loss, up to 72 hours battery support for release and smoke detectors, motor voltage sensing, form-C relay outputs, proximity/down limit detection, annunciator outputs with voice module options and trouble diagnostic capabilities.

CAUTION: Review all installation instructions, procedures, cautions and warnings contained within this manual prior to installing and/or servicing this product. As with all releasing 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. fuse links.

TEST SYSTEM WEEKLY TO ASSURE PROPER OPERATION.

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).

DO NOT install this unit without

INSTALLATION INSTRUCTIONS -To be performed by factory authorized personnel only.

The following installation procedures must be followed to assure performance of the release device/control panel

to factory standards.

A. MOUNTING PROCEDURE

(Figure 1) - Typical installation configuration may not accurately depict door manufacturer’s recommendations. See door manufacturer’s recommendations for use of this product with specific door being installed. All hardware required shall be supplied by the door installer or manufacturer. Use only hardware approved or recognized by the appropriate testing or listing agencies in conjunction with the installation of this product.

1. The release device shall be mounted on a vertical surface with chain end link exiting side of enclosure as illustrated in figure 1.

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, turnbuckles) shall be installed as per Figure 1 or door manufacturers recommendations. Take note that the end link direction of pull is perpendicular to the enclosure side. An eyebolt installed at a minimum distance of

12 inches from the release device will adequately redirect sash chain pull illustrated in figure 1.

*DO NOT install this unit without fuse links!

4. Complete hardware installation by connecting fuse links, sash chain, S- hooks and turnbuckles where 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 Lb. max. pull rating on device.

When installing smoke detectors with this unit refer to NFPA 72 and NFPA 80, for instructions concerning proper placement and detection coverage. See Electrical Connections page 6 for wiring information. End of line devices shall be installed for supervision of electrical power to smoke detectors. “DO NOT” interface this unit to smoke detectors if electrical supervision is not provided!

C. ELECTRICAL CONNECTIONS

Installation of all wiring and connections, including Class 1 and Class 2 circuits, shall be performed in accordance with, but not limited to, the latest NFPA, UL and NEC standards and codes. 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 type, wiring gauge related to power capacity requirements and circuit length and wiring methods. This unit is designed so that it may be used on automated motorized doors which incorporate appropriate safety features. See options below.

Electrical Connections Continued See Figure 2

1. Turn off power supply sources for Model B2 as well as motor where applicable before beginning.

2. Verify voltage rating of release device/control panel to power source being utilized. Model voltage is indicated on side of unit.

3. Connect power source inputs to TB5 (chassis mount), screws 1 & 2. On 24VDC units observe proper polarity by placing positive (+) wire to screw 1. TB5 screw 3 shall be utilized for earth ground where applicable. “DO NOT” connect battery at this time!

* 4.(a) Normally closed initiating devices - remove jumper from TB1 screws 2 & 3. Connect wiring

from N/C initiating device loop to TB1 screws 2 & 3. Auxiliary power (+12VDC) for smoke detectors may be obtained from TB2 which provides it’s power from an internal battery pack. Observe proper polarity, TB2-2 (+), TB2-1 (-). 4 detector maximum.

(b) Normally open initiating devices - Both the N/C and N/O alarm inputs may be used simultaneously,

but if the N/C loop is“ Not” used, make sure jumper is installed across TB1 screws 2 & 3. Connect wiring from N/O initiating device loop to TB1 screws 4 & 5, making sure end of line supervisory resistor (51 Kohm @ 1/4 Watt) is installed as indicated. Auxiliary power (+12VDC) for smoke detectors may be obtained from TB2. Observe proper polarity, TB2-2 (+), TB2-1 (-). 4 detector maximum. Electrical power supervision in the form of an End of Line Device shall be provided on all smoke detectors.

* Note: TB1 initiating device loops are supervised and cannot be directly series or paralleled between multiple release devices or shared with other alarm equipment. For proper wiring configurations from multiple smoke detectors or signalling for simultaneous closure on multiple doors call tech support. Incorrect wiring from unit to unit may cause damage to release and void warranty.

OPTIONS: 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 (Down limit detection)

This option interfaces to electrical contact type lower limit sensing devices and/or magnetic proximity type switches and must be used when the “motor voltage” option is used. If the electrical contact has toggled states from its N/C condition (switch closed when door is “NOT” at lower limit) 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.

5. Connect motor control sensing voltage (24-30V, AC or DC) from motor controller transformer secondary to TB3 screws 1 (+) & 2 (-) Observe proper polarity with DC control voltages.
