The 4101SN V-PLEX Single Output Relay Module is a serial number polling loop output device. The 4101SN
features the following:
• Form C relay contacts rated at 2A, 28VAC/VDC with contact supervision.
The position of the relay is supervised, but not the actual external contact wiring.
• One class B/style B EOLR-supervised auxiliary input zone.
• Operating power and communication with control panels via the V-PLEX polling loop.
• Electronics mounted in a small plastic case with tamper-protected cover.
Connect the device to the polling loop, terminals 24 (+) and 25 (-). Be sure to observe polarity.
NOTE: The panel will not recognize the 4101SN until the zone associated with the device is enrolled in ∗93 Zone
Programming. Zone must be programmed using an input type of "Serial Poll" (06); then enabling the "V-
PLEX Relay" option.
