Installation Sheet
DESCRIPTION
Figure 1: 721T Terminal Block Module
The 721T Terminal Block Module
provides an additional panel-
style zone terminal block with
built-in End-of-Line (EOL) 1K
resistors. Mounting the 721T
in or near the panel enclosure
oers a convenient option for
terminating zone connections in
one location rather than at the
zone device in the field.
Compatibility
• All DMP XR150/XR550
Series panels
What is Included?
• One 721T PCB with foam
backing
1INSTALL THE 721T MODULE
The 721T easily mounts below the panel in most DMP enclosures.
When the rear center knockouts below the panel are used, it may
be necessary to mount the 721T below the knockouts.
1. Remove all power from the panel before installing the 721T.
2. Remove the tape from the 721T foam backing and press the
module firmly onto the enclosure back. Alternately, the 721T
can be permanently mounted using the pre-drilled mounting
holes. See Figure 2.
CONNECT THE TERMINAL BLOCKS
2Use 4-conductor wire to complete the connections between the
panel, the field device, and the 721T. For reference, use a marker to
write the zone device name and number on the 721T in the white
space above the zone terminals. See Figure 2.
How to Connect the AUX Terminal Blocks
1. Connect one end of the black wire to the negative (-) AUX
terminal on the 721T and the other end to panel terminal 10.
See Figure 2.
2. Connect one end of the red wire to the positive (+) AUX
terminal on the 721T and the other end to panel terminal 7.
See Figure 2.

How to Connect N/O Contacts
Follow these steps to connect a N/O (Normally
Open) contact to panel zone 8 in parallel. See
Figure 3.
Note: When a circuit is in parallel, each
component is equal, and the voltage
across the circuit is the sum of the
voltages across each component.
How to Connect N/C Contacts
Follow these steps to connect a N/C (Normally
Closed) contact to panel zone 7 in series. See
Figure 4.
Note: When a circuit is in series, each
component must function to
complete the circuit.
