Connect the Points
Point 1 on the D2112 Only
Terminals 13 and 14
Point 1 on the D2112 is a powered, supervised
point.
The panel monitors the Point 1 sensor loop for
normal, shorted, or open conditions. Programming
determines how the panel responds to those
conditions. See the
D2112/D2112E Program Entry
Guide.
Terminal 13 provides positive (+) voltage to
detection devices. Terminal 14, the loop return (-), is
isolated from earth ground.
The keypad Reset function interrupts power to this
sensor loop to reset smoke or glass break detectors.
Use a 2.0k
Ω
end of line resistor for point 1 on the
D2112. Figure 6 shows point wiring.
Connecting Two-Wire Smoke Detectors
to Point 1 on D2112 Only:
Connect up to five Radionics D262 two-wire smoke
detectors to point 1 on the D2112. Refer to the
Technogram, Smoke Detectors Compatible with the
D2112 (73-07115-000), for a complete list of
detectors compatible with the D2112.
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 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 D2112/D2112E
Program Entry Guide for programming instructions.
Heat Detectors and
Other Dry Contact Initiating Devices
Connect any number (limited by the Authority Having
Jurisdiction).
Burglar Devices
Connect any number (limited by available power) of
burglar devices to any point. Do not combine fire
detection and burglar devices.
Points 2 to 6 (1 to 6 on D2112E)
Terminals 15 to 22 (14 to 22 on D2112E)
Points 2 to 6 (1 to 6 on D2112E) 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
D2112/D2112E Program Entry
Guide .
Terminate each sensor loop with a 1.0k
Ω
end of line
resistor. Figure 6 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 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 D2112/D2112E
Program Entry Guide for programming instructions.
Heat Detectors and
Other Dry Contact Initiating Devices
Connect any number (limited by the Authority Having
Jurisdiction).
Burglar Devices
Connect any number (limited by available power) of
burglar devices to any point. Do not combine fire
detection and burglar devices.
Points 7 and 8 on the D2112 Only
Terminals 23 to 25
Points 7 and 8 are non-powered points that are not
supervised with an end of line resistor.
The D2112 monitors the sensor loops for Points 7
and 8 for normal (closed) and open conditions.
Programming determines how the panel responds to
those conditions. See the
D2112/D2112E Program
Entry Guide . Figure 6 shows point wiring.
