Appendix G: FXMNS Used as a Mass Notification System ( ACU)
The MNS portion of a complete Mircom FleX-Net™ Network Fire Alarm system consists of a BBX-FXMNS
Enclosure (see Node 2 in figure below). The BBX-FXMNS includes a RAXN-LCD Annunciator which is designated
an ACU (Autonomous Control Unit) and a Master Microphone to provide emergency audio. Below the ACU is
another RAXN-LCD which annunciates the fire alarm system along with a Master Telephone for emergency use.
Below this is a display LCD such as the DSPL-420(DS) or DSPL-2440 which may be used for service; this display
will show all messages. Up to seven FX-LOC(R)s can be connected to any MNS node.
The FX-LOC(R) Local Operating Console along with the FleX-Net™ Network Fire Alarm provides compliance with
the Mass Notification System (MNS) UL 2572 requirements.
Applicable Standards: UL 2572, UL 864, NFPA 72, ULC
