1. Model ATM-L Annunciator Driver Module : The Model ATM-L Annunciator Driver Module
provides the ARIES NET Link with up to 32 programmable, supervised LED outputs for
graphical or tabular annunciators, along with six system-level LED outputs and five system-level
input circuits for functional switches. The system-level LEDs correspond to the following general
conditions: Module Power, Pre-Alarm, Alarm, Alarm Silence, Supervisory, and Trouble. The
input circuits for functional switches provide for the following operator intervention: System
Reset, Event Acknowledgement, Alarm Silence, Fire Drill, and Lamp Test.
2. Model ATM-R Relay Driver Module : The Model ATM-R Relay Driver Module can activate up to
32 programmable, supervised relays.
1-14.2.4 FIBER OPTIC CONVERTER MODULE (FOCM)
For network applications with communication paths between nodes greater than 4000 ft., or where
these paths have excessive electrical noise, a fiber-optic option is available for use. The Fiber Optic
Converter Module (FOCM) consists of a bi-directional, externally-powered unit mounted inside a
13 x 7-1/2 x 2 in. enclosure. One of these is required at both interconnected ARIES NET
Link control
units for a single communication channel.
For greater communication security and redundancy, a second optional Add-On module can be
installed in this enclosure to provide an additional channel. This is most effective if the second
channel is installed in a different pathway from the first.
The FOCM is available in two models; one for use with multi-mode (62.5/125
μ
m) duplex fiber-optic
cable with a total transmission distance of 1 mile, and a second for use with single-mode (8.3/125
μ
m) cable with a total transmission distance of 12 miles. Both models connect to the ARIES NET Link
power and RS-485 data lines in the same fashion. The fiber-optic cable connections for both models
are type ‘ST’.
Each FOCM enclosure is equipped with electrical conduit knock-outs for both the fiber-optic cable
and wire connections from the control unit for both 24 Vdc power and the RS-485 data lines.
24 Vdc power can be provided from the PMU Board J9 AUX 1 or AUX 2 terminal block outputs.
These wires are then connected to the FOCM power input terminal block mounted inside its
enclosure. The RS-485 data link connection is provided at the ARIES NET
Link Network Interface
Card (NIC) which is inserted in the Card Cage. Wire connections are made at NIC terminal block J12
(Channel 1) or J13 (Channel 2). (See Section 2-13.1.)
