INTRODUCTION
GENERAL DESCRIPTION
The device provides 3 count obstruction cycling. A safety timer
within the device will turn the motor off and perform a mechanical
release if the lower limit is not detected within a predetermined
time period. Verify factory-installed options to desired features
during initial testing.
Features include a selectable 10, 20, 30 or 60-second time delay
on alarm, remote test, motor voltage sensing, Form C relay
output, lower limit detection, safety timer, battery support for
release device logic, smoke detectors, standard annunciators and
trouble diagnostic capabilities (does not support operator).
Operating voltage is 120Vac.
As with all releasing device systems, maximum fire protection is
provided when installed in accordance with factory specifications
and used with fusible link systems.
The Fire Sentinel AFCB and Fire Sentinel AFCBVB Release Device
is UL/ULC listed normally energized fail-safe device incorporating
state-of-the-art electronic control circuitry. This release device is
designed to be used with manual doors or motorized doors
incorporating a reversing electric safety edge to create an
automated door closing system.
The high performance control panel responds to emergency
conditions generated from an automatic initiating device. Upon
activation, the device will then automatically close a motorized
door or mechanically release a door in the absence of motorized
operation. If the alarm is still present and power is available to the
operator, a motorized door can be opened by depressing the open
switch of the operator, after which the door will close again. If the
door meets an obstruction while in alarm, the door will reverse
and make three attempts to close, after which the motor will be
shut off and the door will rest on the obstruction. The release
device may also be optionally set to fully open the door and
subsequently mechanically release the fire door onto the
obstruction.

WIRING
CONNECTIONS FROM DEVICE TO THE OPERATOR
NOTE: For low voltage wiring #18 AWG is recommended.
OPERATOR CONNECTIONS
1. Connect terminals 11 and 12 from the release device to the
transformer secondary in the door operator. The required
voltage should be 24-30Vac.
NOTE: This connection must be made in order to avoid a
mechanical release in alarm conditions when the door is not
closed (Figure 2).
2. Connect release device to auxiliary limit switches on the
operator. These are required and must be provided by the
door operator manufacturer.
Auxiliary Closed Limit Switch (Figure 1):
Connect a wire from the common and N/O of the auxiliary limit
switch to terminals 13 and 14 on the release device. This input
will not allow a mechanical release if the auxiliary close limit is
activated. This circuit also turns off annunciators when the
auxiliary close limit is activated.
To prevent DAMAGE to the circuit board, auxiliary limit
switches MUST be provided as dry contacts and may not be
used in conjunction with the simultaneous 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.
Auxiliary Open Limit Switch (Figure 1):
Connect a wire from the common and N/O of the auxiliary limit
switch to terminals 14 and 15 on the release device. A
connection to an auxiliary up limit switch is required for
3-cycle obstruction count feature. Adjust the auxiliary open
limit to activate just before the operators open limit is activated.
3. Connect wires from terminals 7, 8, 9, and 10 to the door
operator terminals that are used for 3-button station (for use
with N/O ‘Close’ switch, N/O ‘Open’ switch and N/C ‘Stop’

WIRING
CONNECTIONS OF INITIATING DEVICES AND
ACCESSORIES
To prevent possible SERIOUS INJURY or DEATH:
• End-of-line devices MUST be installed for supervision of
electrical power to 4-wire smoke detector.
• DO NOT install this device on a motorized door without an
electric safety edge.
A maximum of 4 smoke detectors may be installed with this
device. Refer to NFPA 72 and NFPA 80 for instructions
concerning proper placement and detection coverage. End-of-line
devices must be installed for supervision of electrical power to
4-wire smoke detector. When using 4-wire smoke detectors with
this device, electrical supervision must be provided by means of a
UL/ULC listed end-of-line relay.
NOTE: For low voltage wiring #18 AWG is recommended.
Normally Open “2-Wire,” Class B Style A 12Vdc Initiating
Devices
1. Connect wiring from N/O initiating device loop to terminals 2
and 3.
2. Place the supervisory resistor (LMEOLRES-2-2) across the
terminals of the last initiating device. Observe proper polarity,
2 (+), 3 (-) (Figure 3).
OR
Normally open “4-Wire,” Class B Style A Initiating Devices
1. Connect wiring from N/O 4-Wire initiating device loop to
terminals 2 and 3. (Do not share alarm loop with other alarm
circuits.)
2. Place the supervisory resistor (LMEOLRES-2-2) as illustrated
in figure 4 or 5. (Do not share alarm loop with other alarm
circuits.)
3. Auxiliary power (+24Vdc) for smoke detectors may be
obtained from terminals 1 (+) and 4 (-) for +24Vdc. There is a
4 detector maximum, and an end-of-line relay device must be
used (Figures 4 & 5).
NOTE: End-of-line devices must be installed adjacent and after the
last initiating device. Initiating device loops are supervised and
cannot be direct series or paralleled between multiple release
devices or shared with other alarm equipment. For proper wiring
configurations from multiple smoke detectors or signaling for
simultaneous closure on multiple doors, call technical support,
1-800-929-2553. Incorrect wiring between devices may cause
damage to the release control circuit and void warranty.
4. 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 6).
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.

OPTIONAL CONNECTIONS
WALL MOUNTED REMOTE TEST / RESET SWITCH
The provided LMRT-OHD switch should be wall mounted using a
single gang junction box at approx. 4’ above floor level.
Connections should be made between N/O contacts (red and
yellow wires) on the LMRT-OHD to terminals 21 and 22 in the
releasing device (Figure 9). The LMRT-OHD test / reset switch
provides two functions to the releasing device:
1) Test Function. The releasing device can be tested by turning
and holding the LMRT-OHD switch. See Testing section for
details.
2) Alarm Resetting. The LMRT-OHD can be used to reset a
latched alarm condition if the door is closed and the alarm
input has returned to the standby state (alarm is no longer
active). Reset can be accomplished by turning and releasing
the switch. Door may re-open automatically if auto-open
feature is enabled, see DIP Switch Configuration Setting
section.
NOTE: This connection is necessary if floor level resetting of the
device or Auto Opening is required.
To prevent DAMAGE to the circuit board, auxiliary limit
switches MUST be provided as dry contacts and may not be
used in conjunction with the simultaneous 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.
The release device has an 8-position DIP Switch mounted on the
circuit board, and the switch at position #8 permits selection of
either message. In the “ON” position, Message 1 is activated; in
the “OFF” position, Message 2 is activated.
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 8).
Figure 7
Annunciator
ANNUNCIATOR
Connect annunciator (#LMHS2475ADA) to 16 (+) and 20 (–).
End-of-line resistor (LMEOLRES-2-2) must be installed as
illustrated (Figure 7). A maximum of two annunciators may be
connected. Maximum output current of the devices must not
exceed .75A dc. 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. NOTE:
If installing two visual annunciators they must be installed on
opposite walls. If these inputs are not used, place the 2.2k
Ohm resistor from the parts kit between terminals 16 and 20.
ADDITIONAL DRY CONTACT RELAY
An additional dry contact relay is provided between 17
(Common) and 18 (N/C ) and 19 (N/O). Maximum switched
current is .15A 125Vac, 1A 24Vdc. Switching of this relay
occurs immediately upon sensing an alarm.
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.”
