External Power
The Model 40404-045 Plug-in Power Supply is available (sold separately) to provide an increase in the
emergency phone’s speaker output and a reduction in line current consumption. The 40404-045 requires
120 V ac input and provides a 5 V dc output to the unit’s speaker amplifier circuits. The 40404-045 is
provided with a connectorized, 4-foot power cable that plugs into P17 on the telephone PCBA.
N OTE : The 40404-045 is required only when setting the normal speaker volume to maximum does not
produce the desired results or if available telephone line current falls below acceptable results.
Setup
Hardware Configuration
The hardware configuration options are explained in detail in the following sections and the necessary
jumper settings are identified to enable or disable each option. We recommend reading the following
sections, recording the desired parameters, and then making the necessary changes. We also recommend
that you make a record of your settings. The following options are controlled by specific hardware
configurations. See Figure 12 on page 14 for the jumper locations.
Auto-answer Configuration
Factory Setting: Auto-answer feature enabled
The Auto-answer feature enables or disables the automatic answering of an incoming call, which allows
TMA to monitor the health of this phone via polling. When the Auto-answer feature is enabled, the
phone automatically answers the call and attempts to communicate with TMA. If the caller is not TMA,
then the phone rings its sounder to alert a user to lift the handset off-hook.
Enable: Insert the J14 jumper on pins 2 and 3.
Disable: Insert the J14 jumper on pins 1 and 2 (Do not use this setting except under the direction of
GAI-Tronics personnel.)
N OTE : The Auto-answer feature must be enabled during remote programming, and to allow the
GAI-Tronics Telephone Management Application PC to contact the phone.
Polarity Configuration
Factory Setting: Non-polarity sensitive
This telephone can be configured to be polarity or non-polarity sensitive. With the non-polarized setting,
the telephone operates with the telephone line’s positive terminal connected to either the tip or the ring.
With the polarized setting, the telephone only operates with the telephone line’s positive terminal
connected to the tip.
Non-polarity Sensitive: Insert the J6 jumper on pins 2 and 3.
