Overview
This guide provides detailed information about installing the components,
wiring the DuoLink to the exit controller, testing for RF interference, and
component specifications.
The 9450 DuoLink Exit Alarm Receiver is a component of the Exit Alarm
System which is part of the overall 9450 System. The 9450 System
monitors doors, elevators, hallways, and stairwells, to assist staff in
monitoring patients in a facility. A small transmitter is placed on the ankle
or the wrist of a patient. If a transmitter is detected in an Exit Alarm Zone,
an alarm sounds at the exit. Depending on which equipment is installed,
the 9450 System can automatically lock doors, deactivate elevators, and
activate remote cameras.
WARNING: The 9450 System is designed and intended to work in
conjunction with a facility’s overall patient security program, including
reasonable operating policies and procedures. The 9450 System, by itself,
cannot prevent the mismatch, abduction or elopement of patients.

Chapter 1 – Installation
Introduction
DuoLinks are small, unobtrusive devices, placed on or near a door frame
and they interface directly with a Exit Controller to form an Exit Alarm
Zone. They receive Radio Frequency (RF) signals from infant, patient,
and adult transmitters within a monitored zone, and send the signals to
the Exit Controller, which in turn triggers the alarm process. The DuoLink
can be configured to receive either 66 KHz or 262 KHz signals. Its
operating frequency must match the operating frequency of the
transmitters specified for the facility.
DuoLinks are designed to be mounted with just two screws. Placement of
DuoLinks can be critical depending on the width of the door or zone to be
monitored, and the levels of electronic, electrical, and electromagnetic
interference that can be present.
Display
Gain Control Signal LED
When installing product, you must follow standard accepted safety
practices such as wearing safety glasses.
Before cutting openings or drilling holes through walls, you must verify
that you will not strike any wiring or plumbing.
Setting
Frequency
Use the following steps to select the correct frequency for the DuoLink.
The frequency for the DuoLink MUST match that of the transmitters that
are used with the system.
NOTE: The DuoLink can only be configured to operate at one frequency.
WARNING: The factory default setting for the DuoLink is 262 KHz. If the
system has been configured to operate at the 66 KHz frequency, the two
switches inside of the DuoLink will need to be changed to receive 66 KHz
transmitters. Failure to match the frequency will cause the system to not
operate correctly and an elopement could occur.

To select the frequency:
1. Verify that the unit is set to the right frequency by observing the
position of SW1 and SW2 (one switch determines the proper filtering
and the other switch tunes the antenna). Both must be in the correct
position in order for the DuoLink to operate.
Tamper Switch
(deactivated by the Metal
Mounting Bracket)
SW1 = Tuning SW2 = Filter
2. The unit is set to 66 KHz when both the SW1 and SW2 switches are
positioned towards the antenna coil assembly (right in Figure above).
3. The unit is set to 262 KHz when both the SW1 and SW2 switches are
positioned away from the antenna coil assembly (left in Figure above).

Identifying
Potential
Interference
View the receive area around each DuoLink as a cylinder. Keep all
interference sources outside of this cylinder.
Common sources of interference include TVs, computer monitors, electric
motors, electrical distribution panels, and some pagers. These types of
devices must be at least ten (10) feet away from the DuoLink, even
through walls and ceilings. Other sources of interference include:
Some newer electric washers and dryers
Electrical panels and fire alarm panels
Time clock systems
Certain types of fluorescent lights with electronic ballasts
Some elevators
Light dimmers
CAUTION: All DuoLinks must be tested prior to use to verify proper
operation. Failure to test the DuoLinks before use can result in system
failure and/or an abduction or elopement. In addition, failure to test
DuoLinks voids the RF Technologies Product Warranty.

Determining
Location
For optimal location, use the following steps to assess the relative noise in
the environment so that a proper mounting location for the DuoLink may
be chosen. The purpose of this assessment is to make minor adjustments
to the standard mounting configuration in order to achieve an appropriate
location for the DuoLink where its Signal LED indicates minimal activity
with no transmitters in range.
The designed range is 4 feet. The adjustable range surrounding the
antenna location is up to an 8 feet radius, depending on the RF
environment.
NOTE: The following steps are to be performed as a temporary setup.
The final mounting location is not known until the following steps have
been completed.
To determine the location:
1. Use a 5/64” Allen wrench to remove the metal mounting bracket from
the back of DuoLink
2. Set the frequency switches to match the operating frequency of the
transmitters specified for the facility (66 KHz or 262 KHz). Both
switches (SW1 and SW2) need to be set and in the same direction
3. Terminate the DuoLink to the exit controller as per wiring diagram
(see chapter 2)
4. Replace the metal mounting bracket

Chapter 1 – Installation
9450 Duolink Exit Alarm Receiver Hardware Installation Guide Page 13 of 30
0510-1103-G
WARNING: The metal mounting bracket is integral to the tuning of the
DuoLink’s antenna. It must be installed on the DuoLink to get adequate
range performance AND to allow the exit controller to communicate with
the DuoLink. Any modifications made to the mounting bracket will
adversely affect the DuoLink’s performance and could cause an abduction
or an elopement to occur.
5. Make sure the exit controller has been properly mounted and the
power is turned on
6. Hold the DuoLink in its approximate final mounting location. Turn the
20-turn Gain Control clockwise until the LED first starts to blink. Once
the LED begins to blink, turn the Gain Control counter-clockwise one
full rotation (back 360°). NOTE: Turning the Gain Control clockwise
increases the sensitivity, turning it counter-clockwise decreases the
sensitivity.
7. Confirm the range and coverage using the DuoLink and a transmitter,
ensuring the area is covered properly while at the same time not
covering more than what is needed
WARNING: Some door receiver locations are relatively free of the typical
RF noise levels that are found at normal mounting locations in facilities.
For these locations, adjusting the door receiver gain control with the
standard tuning procedure (see step 6 above) can result in too much gain.
Excessive sensitivity to thunderstorm lightning RF noise, excessive
coverage into undesired areas, and over-sensitivity to random occurring
RF noise events (such as floor-buffer/polisher, RFI, and false auto-enrolls)
can be reduced or eliminated by testing the door receiver setup with a test
tag transmitter to confirm that the door receiver has 100% of the needed
coverage and not more. If coverage is tested and found to be excessively
higher than needed, reduce the door receiver gain control counter-
clockwise until there is 100% coverage at that location and not more.
8. Depending on whether the receiver is to be vertically or horizontally
mounted, you must maintain “horizontal” or “vertical” receiver
positioning while assessing the relative noise level
9. Move the DuoLink around in the desired receiver mounting area in
small increments (refer to the mounting configurations on the
following pages) to find a location where the signal LED blinks the
least
10. Mark the spot as it is the quietest radio frequency location and the
DuoLink should be mounted in that area for best performance
WARNING: If the DuoLink has to be moved significantly from the
recommended mounting location, the source of the noise must first be
identified and corrected, and then the location assessment must be
performed again.
11. Power off the exit controller
12. Disconnect the cable from the DuoLink and the exit controller and
proceed to mount the DuoLink
13. Repeat steps for every DuoLink to be mounted in the Exit Alarm Zone

Mounting
The DuoLink can be mounted in both a single or double door
configuration. This section provides detailed instructions about how to
mount the DuoLink in both configurations.
Mounting information to keep in mind:
All receivers must be screwed to the wall using the metal
mounting brackets provided on the back of the receiver. Double-
sided tape is not appropriate for this task.
Do not mount the DuoLink on a steel door frame, unless the
optional isolator is used (0120-0062K). If the door frame is
aluminum, the optional isolator can be avoided.
Antenna should be positioned as close as possible to the door
(without mounting on a metal door frame or directly to the door)
to minimize the effect of RF noise and to improve the coverage
It is not recommended to mount the DuoLink directly to the door.
Doing so will reduce its service life.
Observe DuoLink direction (as illustrated)
Never run wires along the length or inside of the DuoLink
Dimensions as shown are critical for best performance. If EXACT
dimensions cannot be obtained due to architecturally or noise
source constraints, at a minimum, the ferrite coils in the DuoLinks
must be greater than 1 inch apart and must be perpendicular to
each other.
Do NOT install the DuoLink closer than 2 feet in any direction
(including on the other side of a wall) to a 3rd party or RFT card
reader or access control. Doing so may cause the system to not
function properly.To test:
oHold the DuoLink in the proposed location and
bring a card to the reader to observe the LED
signal on the DuoLink.
oWith no transmitters present, the signal LED on the
DuoLink should remain off. Excessive blinking
indicates that the card reader is impacting the
DuoLink’s ability to receive transmitter signals.
oA handheld DuoLink receiver already tuned at the
door can be used to survey any interference if the
2 foot spacing cannot be met.
For wander management systems with residents wearing
transmitters on their ankle, the antennas can be mounted at 36”.
If there will be a mix of wrist and ankle worn transmitters, the top
of the antennas can be mounted at 42”.
