Product Overview
The XNET monitoring-only solution assembly (MOSA) is a cost-effective, monitoring-
only XNET interface designed for connecting a Cerberus Danger Management
Station (DMS) to an XNET FIRE network using a non-UL 864 / non-ULC-S527-11
Listed computer as an ancillary annunciator.
The MOSA transports the XNET protocol over an Ethernet connection between a
MOSA and a Cerberus DMS.
The MOSA is UL / ULC recognized as an ancillary annunciator when used with a
non-UL 864 / non-ULC-S527-11 Listed computer. The MOSA can connect to XNET
FIRE networks comprised of the following: Cerberus PRO Modular, FireFinder XLS,
MXL, Network Command Center (NCC), or Hybrid XNET networks that follows the
XNET rules for hybrid networks.
Additionally, the combination of Model MOSA and a non-UL 864 / ULC-S527-11
Listed PC can replace a Model NCC-2F LifeLINK interface card or SNC, as well as a
UL 864 / ULC-S527-11 Listed PC for connecting the Cerberus DMS to an XNET
network for monitoring-only connections.
See: Details for Ordering section on Page 4 for the list of kit components for Model MOSA.
Specifications
Model MOSA connects to the XNET FIRE
network via the monitoring port on Model
NIC-C located in a Cerberus PRO Modular or
FireFinder XLS panel. Connections to NRC
network rings are also supported where
MOSA connects to the NRC network ring via
the NRC / NIC-C bridge. An assembled Model
MOSA must be installed within 20 feet (6.1
meters) wires in conduit of the
FireFinder XLS/V panel, providing the NIC-C
interface and 24 Volts DC power source to
the MOSA.
The actual distance is limited to 10 feet (3
meters) due to the length of the NIC-C to
XND-M interface cable. In addition, the
assembled Model MOSA must be installed
within 20 feet (6.1 meters) wires in
conduit of the Ethernet switch,
connecting a MOSA to the intranet.
