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.

date and are subject to change without notice.

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.

date and are subject to change without notice.

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.

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.

5.2 Normal standby

When the installation has no off normal conditions the wireless relay outputs will be in the normal

condition with the relay outputs off. The SR-5 will check in to the control panel every 90 seconds to

report its status.

5.4 Trouble signals

This section contains a list of trouble signals that can be transmitted by the wireless relay. Possible

causes are given to help the technician quickly solve the issue. The wireless relay is continuously

monitored for proper operation. If a problem arises then a trouble signal will be sent to the control

panel within 200 seconds indicating the trouble condition. The trouble will be retransmitted every 200

seconds until the problem is resolved. Some of the troubles are self-restoring as listed below.

1. Power Up Reset - Caused when the wireless relay processor resets its program. This signal is

normal the first time the wireless relay is powered up. It should not reoccur after the wireless

relay has power applied. If it does then the unit requires factory service.

2. Low Battery – Caused by battery voltage being too low, battery failing to pass load test or TB6

3+4 terminals open when SW2 is in the 24VDC position. Charge or change the battery or

check the external power supply.

3. Hardware Fault – Caused by a fault with the internal circuitry of the wireless relay. Power

cycle the unit. If the fault repeats then factory service will be required.

4. Charger Failure – Caused by a problem in battery charging circuit or SW2 does not match the

connected input power source. Correct the setting of SW2. If the fault repeats then factiory

service is required.

5. Low Battery – Caused by battery voltage being too low, battery failing to pass load test or TB6

3+4 terminals open when SW2 is in the 24VDC position. Charge or change the battery or

check the external power supply.

6. Power Loss* – Caused by low or no A/C voltage present at the TB7 terminal block or trouble

input TB6 1+2 are open when SW2 is in the 24VDC position. Check for proper A/C supply from

the TR-12V-2A or the external power supply if used.

7. Test Failure* – Displayed by the control panel when the wireless relay polling transmission is

not received within 200 seconds. Possible causes are missing antenna, break in wireless relay

network communications or component failure in the wireless relay. Check the unit for proper

communication with the network.

8. Trouble* – Caused by TB6 5+6 are open when SW2 is in the 24VDC position. Check the

wiring to the terminals or the external power supply.
