Section 3 - Installation
3.1 Preparing the Installation Site
A signal survey must be performed by a factory trained technician or authorized dealer prior to the
installation of the SR-5 wireless relay. The signal survey determines an acceptable location to mount
the SR-5 in order to communicate with the repeaters and control panel. Refer to the Signal Survey
section in this manual for the proper method to conduct a signal survey for this product.
During the survey, try to locate the SR-5 wireless relay close to available 120 Vac uninterruptible
power. The SR-5 can be powered from CWSI model TR-12V-2A plug in transformer or a UL1481
listed power supply. The power connection must be installed in conduit. Warning: The SR-5 wireless
relay input power is 12Vac from the secondary of the TR-12V-2A or 24Vdc from a UL1481
power supply. Do not connect 120Vac directly to the SR-5 or the unit will be damaged.
When connecting primary A/C power always follow:
1- National Fire and Electrical Codes (NFPA 72 and NFPA 70)
2- Local Electrical and Fire Code requirements
3- Local AHJ (Authority Having Jurisdiction) requirements
3.2 Receiving and Unpacking the Equipment
Upon receiving the equipment, the carton should be inspected for damage, which may have occurred
during shipment. Each package should be checked against the packing slip for completeness.
Differences should be reported to CWSI immediately. If any product is suspected of damage it should
be checked for proper operation or returned to CWSI.
3.3 Installing the SR-5 Wireless relay
WARNING: This equipment must be professionally installed by factory trained personnel. Use
of an antenna other than listed in the compatibility section of this manual may be harmful to
persons, void FCC or damage the equipment.
The SR-5 wireless relay must be enrolled into a control panel and programmed in order to function
properly. Enrollment can only be accomplished with the SR-5 within reception range of the control
panel or an enrolled AR-5 repeater. Follow the enrollment instructions in the manual. After enrollment,

it is recommended to hold the wireless relay in the intended mounting location and verify a good
signal survey prior to permanently mounting the unit. Upon enrollment and conducting a signal survey
the unit can be mounted in its intended location. Note: Always attach a compatible antenna to the
sma connector prior to applying power, enrolling or conducting a signal survey with the SR-5.
There are three antennas available for use with the SR-5. The differences are the type and gain. The
OM-1 Omni antenna should be used except where installation space restrictions are an issue. The
OM-2 Omni will have slightly lower gain and is shorter which may be helpful in space restricted areas.
The OM-3 will have increased range over the OM-1&2 where longer omni directional reception is
needed. The YA-1 is a directional Yagi antenna with high gain for signal reception at longer
distances.
When using the YA-1 Yagi antenna follow these steps
1. Perform a signal survey to determine an acceptable indoor location.
2. Attach the mounting brackets to a suitable surface.
3. Fasten the 24” mast to the mounting brackets and tighten the nuts.
4. Attach the YA-1 to the top of the mast and make sure the elements are in a vertical
position.
5. Aim the antenna towards the desired reception location making sure none of the elements
make contact with any surrounding surfaces or objects then tighten the antenna bracket.
6. Connect the supplied cable between the repeater and the antenna. The cable should be
within the same room and not routed near electrically noisy sources such as fluorescent lights
or electrical outlets.
7. Perform a signal survey after the antenna is mounted.
When choosing a mounting location and during installation adhere to the following:
1 – All wiring should comply with national and/or local electrical codes. Unless otherwise
specified, wire should be 18 gauge copper with 600 Volt insulation. Shielded wire is preferred.
2 – This unit is intended to be mounted in indoor dry areas. Avoid dusty, wet and corrosive
locations.
3 – Provide adequate space surrounding the unit to allow for;
a - The hinged cover to be completely opened for easy access to internal components
and wiring.
b - The connection of conduit to the desired cabinet location.
c – The attachment of the antenna to the antenna sma connector.
4 – Avoid electrically noisy locations such as main electrical and transformer rooms,
computer rooms, telephone switching rooms, etc.
5 – Never bring a voltage source higher than 30V into the SR-5 enclosure.
6 – Always maintain a minimum of ¼” between power limited and non-power limited wiring
within the enclosure.
7- Never run power limited and non-power limited wires in the same conduit.
Unlock the SR-5 cover and open the unit. Carefully verify that the unit is not damaged and the printed
circuit board is secured in the enclosure. Hold the SR-5 in its intended position, verify leveling then
mark the location of the upper corner mounting keyholes. Using adequate mounting screws and
anchors, secure the SR-5 wireless relay to the mounting surface. Be sure to install screws in the two
lower mounting holes. WARNING: Make sure A/C supply is turned OFF prior to proceeding with
A/C connection.

Power connection to the SR-5 can be accomplished either by using a CWSI p/n TR-12V-2A low
voltage transformer or by connecting it to a UL 1481 listed power supply. The two methods are
described below.
3.4 Power connection to a TR-12V-2A
The required supply to the TR-12V-2A primary is 120 VAC 60Hz .5A. The A/C
supply is supervised by the SR-5. Follow all applicable electrical codes during
installation. Install conduit from the SR-5 to a Honeywell model 4165
transformer enclosure attached to a 120Vac unswitched outlet located in the
same room (Figure 1). Follow the instructions provided with the transformer
enclosure. Run a two conductor wire from the TR-12V-2A secondary screw
terminals to the terminal block TB7 on the SR-5 board. Set SW2 input power
selection switch to the 12VAC position (Figure 2). Note: A charge fault trouble
will be reported to the panel if SW2 is in the 24VDC position. Attach the
antenna to the SMA1 antenna connector. Do not over tighten the antenna.
Place the control panel in enrollment mode, then plug the TR-12V-2A
transformer into an outlet and connect the backup battery to the BT1 connector
on the SR-5. The wireless relay A/C power and trouble leds will light and the
sounder will beep for 15 seconds. Within one minute the wireless relay should
enroll. The sounder will beep twice and a Power Up Reset trouble signal will be
displayed on the control panel when the SR-5 enrolls. If the wireless relay
doesn’t enroll within 60 seconds:
1. Make sure the wireless relay is in reception range of a repeater or the
control panel.
2. Confirm the control panel is in enrollment mode.
3. Clear the wireless relay base code as described in the info and
maintenance section of this manual and power cycle the unit.
After the wireless relay is enrolled it will transmit a power up reset trouble to the
control panel. This is expected on power up and does not indicate trouble with
the wireless relay.
3.5 Power connection to a UL1481 power supply
The SR-5 can be powered from a UL1481 24Vdc power supply. The power supply should have a
minimum of one general trouble output for connection to the SR-5 trouble inputs (TB6). A trouble
condition with the power supply will be reported to the CWSI control panel as an SR-5 trouble when
the trouble output(s) of the power supply are connected to the SR-5. Refer to the operation section of
the manual for more information. Connect primary power to the UL1481 power supply as instructed in
the power supply manual. All connections from the power supply to the SR-5 are to be in conduit and
contained within one room. Refer to figure 3 for the wiring diagram. Connect the 24VDC output from
the power supply to TB7 on the SR-5. There is no polarity to this connection. Set SW2 to the 24VDC
position (Figure 2). Note: A charge fault trouble will be reported to the panel if SW2 is in the
12VAC position. Three trouble inputs are available on the SR-5 connector TB6. These trouble inputs
are N.C. and only active when SW2 is in the 24VDC position. Any unused trouble input(s) must be
shorted at TB6 or they will report a trouble condition at intervals not exceeding 200 seconds.

The trouble signals sent when the inputs are opened are as follows:
TB6 Terminals Signal on Control Panel
1+2 A/C Loss
3+4 Low Battery
5+6 Trouble
When using the SR-5 with a UL1481 power supply the lithium backup battery in the SR-5 is not
needed and should not be connected.
After the wiring between the SR-5 and the power supply are complete attach the antenna to the
SMA1 antenna connector. Do not over tighten the antenna. Place the control panel in enrollment
mode, then plug apply power to the power supply. The wireless relay A/C power and trouble leds will
light and the sounder will beep for 15 seconds. Within one minute the wireless relay should enroll.
The sounder will beep twice and a Power Up Reset trouble signal will be displayed on the control
panel when the SR-5 enrolls. If the wireless relay doesn’t enroll within 60 seconds:
1. Make sure the wireless relay is in reception range of a repeater or the control panel.
2. Confirm the control panel is in enrollment mode.
3. Clear the wireless relay base code as described in the info and maintenance section of this
manual and power cycle the unit.
After the wireless relay is enrolled it will transmit a power up reset trouble to the control panel. This is
expected on power up and does not indicate trouble with the wireless relay.
3.6 The Backup Battery
Note: This section only applies when using the TR-12V-2A transformer to power the SR-5. The
wireless relay uses a 3.7Vdc 2.8Ah (CWSI p/n BA-3.7V-2.8AH) lithium ion battery for backup power
in the event of primary A/C power failure. The battery will supply a minimum of 24 hours of standby
operation followed by 5 minutes of alarm. The battery plugs into the BT1 connector (figure 3). The
battery is periodically tested under load. The battery is supervised and a low battery trouble will be
transmitted to the control panel every 90 seconds if the battery is low or disconnected. If the battery is
low or bad the low battery trouble will keep reporting until it is charged or replaced with a charged
battery. Note: The battery is to be replaced only by a trained technician.
To replace the battery:
1. Disconnect the battery from connector BT1
2. Cut the tie wraps securing the battery.
3. Replace the battery with a CWSI p/n BA-3.7V-2.8AH battery only. Warning: Use of any
other battery may cause damage/harm to the unit, battery or user.
4. Secure the new battery with new tie wraps supplied with the replacement battery and cut the
excess length of the tie wrap.
5. Connect the battery to the BT1 connector and reset the control panel.
