CONNECTIONS
Relay Connections
The 2032 Alarm Responder provides relay closures only;
they are not intended to supply power. Two groups (GROUP
1 and GROUP 2) of four 12-pin relay connectors are
provided on the rear panel (see Figure 2, page 2). Each group
provides connections for double pole relays. The two groups
provide 32 pairs of relay closures. Figure 3 illustrates the
internal 2032 relay interconnections for Group 1 relays.
The relay connections to the unit must be made with shielded,
2-wire twisted pair (22 AWG or heavier gauge wire or
equivalent). The shield wire is to be connected to the
grounding terminal.
Each set of three pin connections is labeled with a relay
number, from 1 through 32, corresponding to one of the
monitors of the monitor group(s) selected. Each pin within
one of the numbered sets is also labeled, under the connector,
with an A, a B, and a ground symbol. The A and B pins on
each connection are the contacts for one side of each double
pole relay. The contacts for the other side of each relay are
connected to the common Group connectors (next paragraph).
The ground pin is provided for shielding.
One 12-pin connector on the lower right of the 2032 rear
panel contains the common connections for each relay group.
Each set of pins is labeled with the group number G1 IN, G1
OUT, G2 IN, and G2 OUT, and each pin is labeled with an A,
B, and ground. The A and B pins are common contacts for
the other side of the double pole relays; G1 IN and OUT are
connected to relays 1-16 (see Figure 3), and G2 IN and OUT
are connected to relays 17-32. The Group IN connections are
used for determining the function of the associated relays,
such as providing a user-supplied voltage, a short to ground,
or a unique signal on relay activation. The Group IN pins can
also be used as inputs from cascading 2032 units. The Group
OUT connections are used to connect the associated relays to
a single responding device, such as a speaker or an indicator
light, or for cascading to additional 2032's.

For ease of attaching to external equipment, each connector is
supplied with a mating screw terminal connector, shown in
Figure 4. Insert the signal and shield wires into the slots of
the mating connector and tighten the hold-down screws.
When all lines have been connected, insert the 12-pin
connectors into the rear panel mating terminals.
The relay contact ratings are 0.6 Amps at 24 VAC, or 2 Amps
at 30 VDC, resistive load. Power through the relays is not
supplied by the 2032.
Data Line Connections (1995 or 1996)
A DATA LINE is connected from the DATA LINE OUT
BNC on a Matrix Bay to the DATA LINE IN BNC on the
rear panel of the Alarm Responder. (Older 1995 systems
used the term LAN IN/OUT). Use a good grade RG-59 video
cable (Belden 8241 or equivalent). The DATA LINE OUT
BNC on the Alarm Responder must be fitted with a 75-ohm
BNC terminator, or if used to loop to other DATA LINE
controlled equipment, it must be terminated at the end of the
run.
The 2032 must be connected to the Data Line which is used
for the group of monitors to be followed. For 1995 and 1996
systems, Data Line 1 is for monitors 1-64 and Data Line 2 is
for monitors 65-128.
The LED labeled DATA, on the rear panel, will illuminate
when valid code is received on the Data Line.
