Auxiliary Power
Terminal 9
The continuous current draw for powered devices
connected to terminal 9, including keypads, must not
exceed 1.0 A (140mA for fire and combined fire/burglary
systems). Devices powered from this output must operate
over a range of 10.2 VDC to 13.9 VDC.
You must use a minimum of five feet (22 AWG) of wire
when connecting devices mounted outside the
enclosure to terminal 9. A short on terminal 9 within five
feet of the panel prevents the panel from operating correctly.
Checking Continuous Current Draw
The panel allows you to check current draw using the
keypad. For more information about this and other keypad
diagnostic features, see the
D2212 Keypad Diagnostics
manual (74-07385-000).
External Relays
Terminals 11 and 12
You can program terminals 11 and 12 to provide outputs for
two external relays. Review
RELAYS in the D2212 Program
Entry Guide for a description of the relay functions available.

Connect a D133 Relay Module for each of the external relay
outputs you intend to use, or one D134 Relay Module for two
external relay outputs. The D134 is essentially two D133
modules on a single board. Figure 4 shows the connections.
Warning: Do not connect wiring for external devices directly
to terminals 11 or 12. Install D133/D134 modules connected
to terminals 11 and 12 in the enclosure with the panel as
shown in Figure 1. The D133 draws 36mA when energized.
When both relays are energized, the D134 draws 72 mA.
Connect the Points
On-Board Points
Point 1
Terminals 13 and 14
Point 1 on the D2212 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 these conditions. See the
D2212
Program Entry Guide.
Terminal 13 provides positive (+) voltage to 2-wire 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 detectors.
Use a 2k
Ω
end-of-line resistor (P/N 15-03130-010) for Point
1. Figure 5 shows Point wiring.
Connecting Two-Wire Smoke Detectors to Point 1:
Connect up to 15 Radionics D262 two-wire smoke detectors
to Point 1. Refer to the
Technogram: Smoke Detectors
Compatible with the D2212 (73-07358-000), for a complete
list of detectors compatible with the D2212.
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).
