Auxiliary Power and Switch Wiring
The radio module connects to an associated switch through a station port. Normally, a radio module is powered
through one or both of its station port interfaces. However, there may be occasions when an auxiliary power
supply may be required. The auxiliary power supply can be connected to either of the radio module’s station
ports.
With 24-gauge wire, the maximum loop length of a radio module connected with a
PARTNER or MERLIN system is 1,000 feet (305 m). When the radio module is
connected with a MERLIN MAGIX or DEFINITY system, the maximum loop length
is 2,000 feet (610 m). However, with auxiliary power, radio modules connected to
these systems will have a maximum loop length of 3,000 feet (915 m).
The following auxiliary power supplies are preferred: The 1151A1 Power Supply
(PEC: 2404-010A; Comcode: 108212952) or the 1151A2 Power Supply with Battery
Holdover (PEC: 2404-012A; Comcode: 108212960).
Note: If you are using an auxiliary power supply, the MDW 9040 Pocket Phone
has a built-in testing feature that you can use before final installation
(station wiring run) to help determine proper placement of the radio
module. To perform the tests, you need an electrical outlet for the radio
module, a 14 foot (4.2 m) Station Line Cord (provided) with the auxiliary
power supply, and a charged battery pack in the handset (you do not need
a communications system switch or control unit). The tests are described
in “
Using Wireless Test Mode ” in Chapter 5 .
Be sure the radio module does not share the same power line as equipment with
microprocessors such as answering machines, personal computers, and fax machines
or electromagnetic equipment such as electric motors.
