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.
RELAY AND TROUBLE OUTPUTS OPTION
Connect wiring from the Alarm Relay Outputs (#11 N/C or #13 N/O
and #12 Common) to the appropriate inputs on the Fire Alarm Control
Panel to provide a signal at the panel when the release device is in an
alarm state. Connect wiring from the Trouble Relay Outputs (#14 N/C or
#16 N/O and #15 Common) to the appropriate inputs on the Fire Alarm
Control Panel to provide a signal at the panel that the release device is
in a trouble state (Figure 9). If these features are desired, coordinate the
interconnection between the Release Device and the Fire Alarm Control
Panel with the fire alarm installer.
ANNUNCIATOR OPTION
To power one or two (maximum) horn/strobes or similar annunciators,
connect wiring to terminals 9 and 10 (Figure 10). Route wires through
the non-conductive sleeving (provided) covering any exposed bare
wires. Maximum distance of wire run within conduit not to exceed 20'
total. This is a supervised, non power-limited circuit.
NOTE: If installing two visual annunciators, they must be installed on
opposite sides of wall. If unused, place 10k Ohm Resistor between
positions 9 and 10.
CONNECTIONS OF INITIATING DEVICES AND ACCESSORIES (cont’d)
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.

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 LMSP24R)
or speaker inputs to speaker strobes (Model LMSS24R). 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).
DIP SWITCH SELECTION
The release device will provide a factory default delay of 10 seconds (to
minimize nuisance alarms) before releasing the fusible link chain upon
alarm or power loss. A 4-position DIP Switch found on the PC board
within the release device can be used to adjust the length of the delay to
one of four preset delays.
The optional delay settings are as follows:

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.
Is the Red LED Lit?
Yes Move on.
No Check power connections per Wiring Diagram.
Check voltage; voltage should be 120Vac, 24 Vac or 24Vdc
connected as part of the wiring diagram.
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.

Troubleshooting
CIRCUIT BOARD DIAGNOSTIC LEDS
View diagnostic LEDs present on the circuit board located behind the terminal block (See Wiring Diagram).
Refer to the table below for the status LED indications.
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.
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.
N/O Detector
Trouble
Yellow (LED 6) If lit, indicates a trouble condition (open) within the N/O 2-wire (or 4-wire) smoke detector loop (emanating from
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
Alarm
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
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
Trouble
Red (LED 4) If lit, indicates an open circuit within the N/C 4-wire smoke detector loop (emanating from terminal board positions
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
Detection
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
Door Detection section of this manual for correct wiring instructions (Figure 8).
Annunciator
Trouble
Yellow (LED 9) If lit, indicates a trouble condition (open) within the annunciator loop (emanating from terminal board positions
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.

ENCLOSURE MOUNTED LEDS STATUS INDICATORS
Battery Green If the Green LED is lit, then the battery is connected
properly and charged above the minimum acceptable level.
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.

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).
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.
BATTERY DISPOSAL
Spent batteries must be treated as hazardous waste and disposed of in
accordance with State, Local and Federal Regulations.
To prevent possible SERIOUS INJURY or DEATH:
• Stand clear of path of door.
• Disconnect ALL electrical and battery power BEFORE performing
maintenance.
