Relay Module Installation
In lieu of smoke detectors, the release device may be put into alarm by
the fire alarm control panel. Most commonly, a relay module is used as
an interface between the fire alarm control panel and the release device.
The relay module must provide Form C dry contacts for connection to
the appropriate terminals on the release device (Figure 7).
NOTE: When choosing a relay module to activate the release device in
an alarm condition, always select one that provides Form C dry contact
relays. Do not use any relay module providing or passing any (control)
voltage through the contacts into the release device. The passage of
voltage through such a relay module into the release device will cause
problems with the operation of the device and may damage the device’s
terminals and/or circuit board. Make certain that the 10k ohm resistor is
placed between positions 3 and 4.
To prevent DAMAGE to the circuit board, ALL connections from
terminals 3 through 16 MUST be dry contact type.

OPTIONAL CONNECTIONS
CLOSE DOOR DETECTION OPTION
Connect wiring from N/O electrical loop, using a proximity switch or
other similar device with dry contacts, to 7 and 8 (Figure 8). The switch
should be placed to engage when the door is in the closed position
and so that it will toggle states from its N/O condition (switch closed
when door is closed) to a closed condition indicating that the door
edge has made contact with desired down position. When the switch
is closed by contact from the door, the release device will not activate
on alarm, thereby eliminating nuisance gravity drops through the
inadvertent release of the fusible link assembly. This option only works
as long as power is available to unit. Fail-safe operation is maintained
under all operating conditions, and if power is not available to the
unit, the fusible link assembly will be released. This is a power-limited,
unsupervised circuit. This proximity switch must be mounted in the
same room as the release device.

VOICE BOARD OPTION
The voice board provides one of two verbal warnings that the fire door
is closing. Typically, depending on the length of the delay chosen on the
release device, a warning tone will occur prior to the message, which
is approximately 10 seconds in length (for example, a 20 second delay
setting on the release device will result in a 10 second warning tone
followed by the verbal warning message). There are two messages that
may be selected:
Message 1: Warning tone followed by the message, “Warning! An
emergency condition exists and this fire door is about to close;
please remove any obstructions from its path and stand clear.”
Message 2: Warning tone followed by the message, “Warning!
This fire door will close in 10 seconds... 5 seconds... the fire door
is now closing; please remove any obstructions from its path and
stand clear.”
The release device has an 4-position DIP Switch mounted on the
circuit board, and the switch at position #3 permits selection of either
message. In the “ON” position, Message 1 is activated; in the “OFF”
position, Message 2 is activated (Figure 12).
The voice board can drive up to two 70.7V speakers (Model LM8SP)
or speaker inputs to speaker strobes (Model LMPSTR2475ADA).
Maximum delivered power is 5 watts.
A potentiometer (VR1) is mounted on the board and rotation
counterclockwise increases the volume (clockwise to decrease volume)
(Figure 11).

to unit. The release device is designed to operate with power applied.
NOTE: Testing shall be performed and witnessed for proper operation.
CLOSE DOOR DETECTION (OPTIONAL)
1. Using the chain hoist or motor operator, lower the door to fully
closed position.
2. Verify that Release Disabled LED (yellow) is lit indicating door
closure. Depress and continue to hold test button on side of
release device for 10 seconds. Close Door Detection logic will
prohibit the release device from energizing and releasing the end
link. Reset the test button (Figure 13).
3. Raise door to fully open position.
SUSPENSION OF POWER
1. Make sure door is in fully open position. Turn off all power to
release device and disconnect battery. Immediately upon loss of
power (line voltage and battery backup) to the release device, a
mechanical release will be initiated.
2. Reset the door per door manufacturer’s instructions. Raise the
door and then reset the release device by pushing downward on
the Mechanical Reset Plunger at the top of the device. Fully insert
the end link through the side opening on the device and release
the Mechanical Reset Plunger in order to latch end link. Press the
“Reset” button on the device to reset the alarm loop.

Troubleshooting
OPERATIONAL CHECKLIST
POWER
Is the red LED, labeled “Power,” located on the bottom of the enclosure
lit?
To prevent possible SERIOUS INJURY or DEATH:
•
Clear fire door opening and prohibit ALL traffic through door
opening while trouble shooting.
Is the Red LED Lit?
Yes
Move on.
No
Check power connections per Wiring Diagram.
CHECK THE CLOSE DOOR DETECTION
Is the Yellow LED on the bottom of the enclosure lit? If lit, the close
limit detection input is active, the devise is disabled and will not
perform a mechanical release.
Check voltage; voltage should be 120Vac, 24 Vac or 24Vdc
connected as part of the wiring diagram.
CHECK THE BATTERY CONNECTIONS
Is the Green LED on the bottom of the enclosure lit? If so, the battery
is connected properly. If the LED does not light, the battery is not
functioning properly and a trouble sounder will annunciate. Check the
following:
1. Are the battery leads properly connected or do the leads have a
defective connector?
2. Do the battery connections observe correct polarity — Red (+)
and Black (–)?
3. Is the battery discharged? If so, allow 10 minutes for the battery
management system to recharge the battery. If the sounder does
not stop after this time, then the battery needs to be replaced.
Refer to the “Replacement Parts and Accessories” section of this
manual for ordering instructions.
Battery Performance Inconsistencies - Does the unit go into alarm
and release the fusible link as soon as power is applied? If so, then
check the wiring and connections on the smoke detector loop, focusing
especially on the presence and the correct placement of the end-of-line
resistor. Also, if N/O smoke detectors are being used, make certain
that the Wire Jumper between positions 5 and 6 on the release device’s
terminal strip is in place.
CHECK THE ALARM
Are the alarm (smoke detection) inputs correct? If not, the release
device will not release the fusible link assembly in a fire condition.
Conversely, the release device will always release the fusible link
assembly when powered or reset.
Are the Alarm Inputs correct?
Yes
Move on.
No
Check that it is a dry contact input. There should not be any
voltage on the alarm lines when they are disconnected from
the unit.
Verify that all wiring is per manufacturers’ instructions.

terminal board positions 3 and 4), resulting from either incorrect wiring or incorrect placement of the end-of-line
resistor, and the smoke detector loop is inactive. Refer to the Smoke Detector Installation section of this manual
for correct wiring instructions (Figures 3-5).
N/O Detector Red (LED 5) If lit, indicates that the N/O 2-wire (or 4-wire) smoke detector loop (emanating from terminal board positions 3 and
Alarm
4) is in alarm. When lit during testing, press the Auxiliary Reset Button at the bottom of the release device to reset
the loop (Figures 3-5).
N/C Detector Red (LED 4) If lit, indicates an open circuit within the N/C 4-wire smoke detector loop (emanating from terminal board positions
Trouble
5 and 6), resulting from either incorrect wiring or incorrect placement of the end-of-line relay or the detector(s)
are in alarm. If in alarm, cycle power off and then on to the smoke detectors to reset, then depress the auxiliary
reset button to reset the release device. Refer to the Smoke Detector Installation section of this manual for correct
wiring instructions (Figures 6 and 7).
Close Door Green (LED 2) If lit, indicates that the fire door or shutter is closed and activating the proximity switch. If not lit, refer to the Close
Detection
Door Detection section of this manual for correct wiring instructions (Figure 8).
Annunciator Yellow (LED 9) If lit, indicates a trouble condition (open) within the annunciator loop (emanating from terminal board positions
Trouble
9 and 10), resulting from either incorrect wiring or incorrect placement of the end-of-line resistor. Refer to the
Annunciator section of this manual for correct wiring instructions (Figure 10).
Ground Fault Yellow (LED 3) If lit, indicates that one of the ancillary devices/loops (smoke detector, annunciator, etc.) is not grounded properly,
and a short to earth ground exists.
Figure 14
GROUND FAULT ERROR
When a separate device (fire alarm control panel) with its own ground
fault is introduced, the potential for the release device to recognize a
“double-ground fault” error exists. In the event that this Ground Fault
error occurs, the ground fault light on the board will illuminate and the
system will begin beeping.
Aluminum
Standoff
TO CORRECT THE GROUND FAULT ERROR:
1. Disconnect power to the unit, both line and battery power.
NOTE: Mechanical release will be initiated upon loss of power.
2. Locate the aluminum standoff that is part of the grounding system
in the unit (Figure 14).
3. Carefully remove the two screws holding the aluminum standoff in
place.
4. Once the aluminum standoff has been removed, reconnect line
voltage and battery wires.
If the Ground Fault error has been cleared, the release device will
operate as intended. Auxiliary fire alarm devices attached to the device
are now providing the ground fault protection monitoring.
If the Ground Fault error remains, proceed with regular troubleshooting.
Disconnect accessories one at a time checking if the Ground Fault
error clears.

Maintenance
MAINTENANCE REQUIREMENTS
The release device has no scheduled maintenance requirements. The
unit has been designed and tested for use in dry, indoor locations.
Testing of the unit at least once every 90 days is recommended, but
test intervals shall ultimately be subject to criteria established by the
Authority Having Jurisdiction (AHJ).
To prevent possible SERIOUS INJURY or DEATH:
•
Stand clear of path of door.
•
Disconnect ALL electrical and battery power BEFORE performing
maintenance.
FUSE REPLACEMENT PROCEDURE AND REPAIR PARTS
One serviceable fuse, a 3 Amp, 3AG, slo-blo fuse, is required for proper
operation and protection of the circuit board. The release device is
shipped with the fuse in place and two replacement fuses are provided
in a separate parts bag. The fuse is located on the circuit board near the
battery cable connection.
For replacement parts refer to Accessory and Replacement Parts page.

BATTERY MAINTENANCE/TESTING
No maintenance or testing is required for the battery. An audible
warning tone, generated by the trouble annunciator mounted to the side
of the release device, will sound when the battery is approaching the
minimum operating threshold. This indicates the need to replace the
battery. It is recommended that the battery be replaced every 2 years.
For replacement parts refer to Accessory and Replacement Parts page.

Description
If the Green LED is lit, then the battery is connected
properly and charged above the minimum acceptable level.
Action Required
If the LED does not light, check that the leads are
connected to the battery as shown on the wiring
diagram.
Disable
Yellow
The Yellow LED will light when the door reaches the close
limit and activates a proximity switch attached to terminal
positions 7 and 8 on the release device. This configuration
results in the device not releasing the fusible link assembly
in alarm or power loss situations and should only be used
when the fire door is kept in a constant closed position.
If the LED does not light when the door reaches the
close door detection and activates the proximity
switch, then check that the proximity switch has
been activated and that the switch is set to normally
open (N.O.). Check to make certain that the switch is
attached to terminal positions 7 and 8 on the release
device.
Power
Red
If the Red LED is lit, then the line power is connected and
switched “on.”
If the LED does not light when power is applied, check
that power is connected as described in the installation
manual electrical connections.
