26 Installing the XM-441 Expansion Relay Module
1. Make certain the keyswitch (A) on the terminal base unit (C) is at
position 3 as required for the XM-441.
2. Make certain the side connector (B) is pushed all the way to the left. You
cannot install the module unless the connector is fully extended.
3. Make sure that the pins on the bottom of the module are straight so they
will align properly with the connector in the terminal base unit.
4. Position the module (D) with its alignment bar (E) aligned with the
groove (F) on the terminal base.
5. Press firmly and evenly to seat the module in the terminal base unit. The
module is seated when the latching mechanism (G) is locked into the
module.
6. Repeat the above steps to install the next XM-441 module in its terminal
base.
Module Indicators The XM-441 has a power status indicator (PWR) that is on when power is
applied to the module and an activation status indicator for each relay (four in
all). The indicators are located on top of the module.
