Unlock the WRA-3 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
WRA-3 in its intended position, verify leveling then mark the location of the
upper corner mounting keyholes. Using adequate mounting screws and
anchors, secure the WRA-3 annunciator to the mounting surface. Be sure to
install screws in the two lower mounting holes. Additionally the annunciator
can be secured to a flush mount 4” gang box if desired using the 4 holes in
the back box.
WARNING: Make sure A/C supply is turned OFF prior to
proceeding with A/C connection.
The required supply to the TR-12V-2A
primary is 120 VAC 60Hz 2 Amps. Follow all applicable electrical codes.
Install conduit from the WRA-3 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 J23 on the WRA-3 board. Place the anti tamper washer
over the small end of the antenna then screw the OM-1 omni antenna to the
SMA1 antenna connector making sure the washer is on the inside of the front
cover lip. Do not over tighten the antenna. Place the CP-3000A(DA) in
enrollment mode then plug in the transformer and connect the backup battery
to the BT1 connector on the WRA-3. Close and lock the cover making sure
the anti tamper washer is inside the enclosure. The annunciator leds will light,
sounder will beep and the lcd display will indicate initialization. Within one
minute the annunciator should enroll and exit initialization. If the annunciator
doesn’t enroll within 90 seconds a “Not Enrolled” message will be shown on
the lcd.
If you see this message:
1. Make sure the annunciator is in reception range of a repeater or the control panel.
2. Confirm the CP-3000A(DA) is in enrollment mode.
3. Clear the annunciator base code as described in the info and maintenance section of this
manual.
After the issue is corrected press the reset button on the annunciator board to start the initialization
routine again.
After the annunciator is enrolled it will transmit a power up reset trouble to the CP-3000A(DA). This is
expected on power up and does not indicate trouble with the annunciator. A checksum trouble will
also be present on the
CP-3000A(DA) and annunciator. The checksum trouble can only be cleared by programming the
annunciator with the installation site data. Refer to the programming section of this manual and the
CP-3000A(DA) manual.
3.4 The Backup Battery
The annunciator uses a 3.7Vdc 3Ah (CWSI p/n BA-3.7V-3AH) 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. A low battery trouble will be transmitted to the CP-
3000A(DA) 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.
To replace the battery:
1. Disconnect the battery from connector BT1
