- The AUX1 will Close when the Red LED turns ON
and Open when the Red LED turns “OFF”.
•

AUX2 (optional):
The AUX2 output is used for phone line monitoring.
When a good phone line is connected to the unit this output is normally
open. If the telephone line drops below 2 volts, is disconnected, or
shorted for more than 15 minutes, this output will close.

connected to the P9 connector and a jumper is installed at the LM
connector on the board.
Battery and Power Supply Information
The following information explains how to determine when a battery or
power supply is needed or when to use a specific type of battery:
You will need a 9V battery or a 9-24VDC/12VAC power supply with
8.4V NiMH battery when:
1.
The phone drops off the telephone line without completing the call.
2.
There is more than one phone on the same telephone line and there is
a need to call back to a specific elevator phone, or if all elevator
phones need to be “ON” at the same time.
9-24VDC/12VAC Power Supply:
Can be used on all phone lines. The
8.4V NiMH battery supplied with the power supply will need to be checked
every 12 months. An AC connection is required and the battery will be
charged by the power supply connected to the P9 connector of the board.
The P9 connector is polarity sensitive so use caution when connecting to
it (P9 is labeled with + and -).
CAUTION: DO NOT
use an alkaline or lithium battery when the power
supply is connected to the P9 connector.
