The Network Main Controller Module (MCMN) is the foundation of
the network and contains the principal microprocessor and controls
for the fire alarm system.
The MCMN has a dual-purpose RS-485 port. The network
terminals (NET) provide Class A (Style 6) or Class B (Style 4)
communications for the network. The annunciator terminals (ANN)
provide communications with 2-LSRAs, 2-SMDNs, and SAN
Annunciators.
The MCMN also has an RS-232 port to provide communications
for printers. An RJ-11 jack provides a means for downloading
programmed data from an IBM compatible computer to the MCMN.
All external connections are transient-protected.
The MCMN provides one multiplexed Signature Data Circuit (SDC)
and two Notification Appliance Circuits (NACs). The SDC and the
NACs can both operate on Class A or Class B wiring. The SDC
can support 96 Signature Series detectors and 94 Signature
Series modules. The NACs have separate input terminals, which
are rated at 24 Vdc @ 3.5 A or 100 W @ 25 Vrms or 70 Vrms
audio. The NAC terminals may share power or receive it from an
external source.
During alarm, supervisory, and trouble conditions the MCMN relay
contacts close to report the off-normal conditions. There are two
Form C relays and a Form A relay. The Form C relays handle
alarm and trouble conditions and operate on 24 Vdc, nominal @ 1
A. The Form A relay handles supervisory conditions and operates
on 24 Vdc, nominal @ 1 A.
