Installing the XM-160/161/162 Direct Vibration Module 23
Figure 2.10 Loop-powered 4-20mA Connections
Connecting a Remote Relay Reset Signal (XM-161 & XM-162)
If you set the relay (physical or virtual) 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 the relay remotely after you
have corrected the alarm condition.
The Direct Vibration modules do not have an on-board relay. The relays are
added when an Expansion Relay (XM-441) module is connected to the Direct
Vibration modules. The Direct Vibration modules support two Expansion
Relay modules for a total of eight relays.

TIP
If you set a module relay to latching, make sure that any
linked relays, such as relays in an XM-440 Master Relay
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.
TIP
You can reset individual relays using the serial or remote
configuration tool.
