Introduction
Figure 1: D7212 System Configuration
Points
The Radionics D7212 Control/Communicator panel provides up to 48 separate points of
protection. Point programming parameters determine the panel’s response to open and
shorted conditions on the point’s sensor loop. Points are programmed individually with
several options to custom-fit the protection to your installation.
Points 1 to 8 are located on the D7212 circuit board (on-board points). They are standard
sensor loops. The remaining 40 off-board points are POPIT (Point of Protection Input
Transponder) points. Each off-board point requires a POPIT module. D8127 POPIT
modules require the D8125 POPEX module. The D8128A OctoPOPIT module combines
eight POPITs in a single module and does not require the D8125 POPEX module.

(Other functions available.)
Use D1255 Command Centers and/or
keyswitches to arm the D7212 by area. Each
panel can have up to 8 areas. Each area can
have its own account number or areas can be
grouped together with a common account number.
Points of protection are assigned to areas.
D128 module allows the
D7212 to monitor two phone
lines.
D9131 module connects
to a parallel printer to
print event log locally.
