Point Expanders, Wired or RF
Points are connected by wire to D222 keypads, or if RF
Points are used, they transmit to an RF Receiver.
You can expand 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
D2212 Program Entry Guide (74-07386-
000) for more information.
For UL installations, wire a sounding device (e.g. a buzzer)
to one of the external relays (terminal 11 or 12) and to
terminal 6 (alarm output). See Figure 5. Program the relay
for Function 3 to provide annunciation of troubles for all fire
points (see
RELAYS in the D2212 Program Entry Guide).
Points Connected to D222 Keypads or D208 Point
Expanders
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 these conditions. See the
D2212 Program
Entry Guide.
Terminate each sensor loop with a 1.0k
Ω
end-of-line
resistor. Figure 5 shows Point wiring.
RF Points
RF Points transmit a radio frequency signal to an RF Point
Expander Module. The module decodes the signal and
sends the RF Point status to the D2212.
Burglary Devices
Connect any number (limited by available power) of burglary
devices to any point. Do not combine fire detection and
burglary devices on the same point.
Points 2 to 6
Terminals 15 to 22
Points 2 to 6 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 these conditions. See the
D2212
Program Entry Guide .
Terminate each sensor loop with a 1.0k
Ω
end of line
resistor. Figure 5 shows Point wiring.
Four-Wire Smoke Detectors
Connect any number (limited by available power and the
Authority Having Jurisdiction) of 12 VDC four-wire smoke
detectors to any supervised point. Install a suitable power
supervision device according the manufacturer's instructions.
Route the power for the detectors through a D133/ D134
Relay Module. The relay module must be connected to one
of the panel's external relay outputs programmed for the
reset function. See
RELAYS in the D2212 Program Entry
Guide for programming instructions.
Heat Detectors and other Dry Contact Initiating Devices
Connect any number (limited by the Authority Having
Jurisdiction).
Burglary Devices
Connect any number (limited by available power) of
burglary devices to any point. Do not combine fire
detection and burglary devices on the same point.
Points 7 and 8
Terminals 23 to 25
Points 7 and 8 are non-powered points that
are not supervised with an end-of-line
resistor.
The D2212 monitors the sensor loops for
Points 7 and 8 for normal (closed) and open
conditions. Programming determines how
the panel responds to these conditions. See
the
D2212 Program Entry Guide . Figure 5
shows Point wiring.
For UL systems, points 7 and 8 can only
be used for tamper contacts. Tamper
contacts must be installed within the
protected enclosure.
