the WRA-3 in order to communicate with the AR-3A repeaters and CP-3000A(DA) 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 WRA-3 annunciator close to available 120 Vac uninterruptible
power. The WRA-3 is powered from CWSI model TR-12V-2A plug in transformer. The power
connection must be installed in conduit.
Warning: The WRA-3 annunciator input power is 12Vac
from the secondary of the TR-12V-2A. Do not connect 120Vac directly to the WRA-3 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

3.3 Installing the WRA-3 Annunciator
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. Always attach an OM-1 antenna to the sma
connector prior to applying power, enrolling or conducting a signal survey with the WRA-3.
The WRA-3 annunciator must be enrolled into a CP-3000A(DA) control panel and programmed to
function properly. Enrollment can only be accomplished with the WRA-3 within reception range of the
CP-3000A(DA) or an enrolled AR-3A repeater. Follow the enrollment instructions in the CP-
3000A(DA) manual. After enrollment, it is recommended to hold the annunciator 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. The
following must be considered and or adhered to when mounting the unit. The maximum repeater
depth between any annunciator and any device is 20. The panel must be included in the path
between the annunciator and the furthest device when figuring the repeater depth. There is a limit of
8 annunciators per CP-3000A(DA).
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 omni antenna to the antenna sma connector.
4 – Avoid electrically noisy locations such as main electrical and transformer rooms,
