Point Expanders for the D2212B, Wired or RF
Point expanders are only compatible with the D2212B; they are not compatible with the D2212BE.
Points are connected by wire to D208 Point Expanders, D222 keypads and/or if RF Points are used, they transmit to an RF
Receiver.
You can expand the D2212B to 24 points using wired and/or RF point expanders. On-board point numbers are fixed from
Point 1 to Point 8. If you use an on-board point, you must use its point number (see the D2000 Series Program Entry Guide
[P/N: 35114] for more information).
Points Connected to D222 Keypads:
Points are supervised, non-powered points.
The panel monitors sensor loops for normal, shorted, or open conditions. Programming for each point determines how the
panel responds to those conditions (see the D2000 Series Program Entry Guide [P/N: 35114]).
RF Points:
RF Points transmit a radio frequency signal to an RF Receiver. The RF Receiver decodes the signal and sends the
RF Point status to the D2212B.
