32 Installing the XM-440 Master Relay Module

Connecting the Remote Relay Reset Signal

If you set the module relay to latching and the relay activates, the relay stays
activated even when the condition that caused the alarm has ended. The
remote relay reset signal enables you to reset your module relay remotely after
you have corrected the alarm condition. This includes latched relays in the
Expansion Relay module when it is attached to the XM-440..

Wire the Remote Relay Reset Signal to the terminal base unit as shown in
Figure 2.13.

TIP

You can discretely reset a relay using the serial or remote
configuration tool.

TIP

If you set a measurement module relay to latching, make
sure that any linked relays, such as relays in an XM-440
module, are not configured as latching. When both relays
are set to latching, the relay in each module will have to be
independently reset when necessary.

ATTENTION

The Switch Input circuits are electrically isolated from
other circuits. It is recommended that the Switch RTN
signal be grounded at a signal point. Connect the Switch
RTN signal to the XM terminal base (Chassis terminal) or
directly to the DIN rail, or ground the signal at the switch
or other equipment that is wired to the switch.
