2102 Alarm Panel
1.2 Configuration
The Model 2102 is available with or
without a built in audible alarm at the
controller:
Model 2102-00: Standard Controller.
Model 2102-01: Controller with audible
alarm annunciator (common to both gas
monitors) installed in the enclosure door.
The standard controller is provided with
the relays configured for separate
activation by their respective gas
monitors. (i.e.: Monitor #1 activates
relay #1 and sensor #2 activates relay
#2).
On request, the factory installs a jumper
wire to re-configure the relays to activate
on an “or” basis so that when either
sensor alarms both relays energize. This
jumper is indicates in the locator
diagram and van be field installed by a
technician.
2.0 Operation
2.1 Installation
Determine suitable locations for the
Model 2102 and the fixed gas monitors.
Mount the panel at eye level using the
mounting flanges on the top and bottom
of the enclosure. Install ¾” electrical
conduit from the right hand tub to the
monitor locations. For installation
convenience the wiring for both sensors
can be run in the same conduit
necessary. Pull four conductors for each
monitor. See Table 1 for wire gauge
requirements. The normal SMC color
coding is green, red, black, white.

Connect these wires to the terminal strip
in the gas monitor and to the
corresponding terminal in the gas
monitor and to the corresponding
terminal in the Central Panel. The four
terminal barrier strips in the Model 2102
are marked “SENSOR 1” and “SENSOR

Table 2 Model 2102 Terminations
Connect to the appropriate terminal strip
pin # (as marked) in the fixed gas
monitor.
CAUTION: The terminal strip positions
in the gas monitor are marked with the
correct numbers as they are not in
logical sequence, insure that the wires
are installed in the correspondingly
numbered positions, not in logical
sequence.
Connect ¾” conduit to the left hub of the
enclosure to run 120 VAC power wiring
to connect externally operated alarms,
lights or fans to the relay terminal strips
as required.
The relay terminal strips are identified as
“J2” corresponding to Cannel 1 and “J3”
corresponding to Channel 2. The
connections can be used as follows:
