Power Outputs
D2212 Circuit Protection
Two self-resetting protection devices protect the panel from
short circuits on both the auxiliary and alarm power outputs.
Bell circuit protection: A short on the alarm power output
while the bell is ringing disables this output until it times out
or a panel reset has been performed.
Extra Power for Keypad or Other Powered Devices
You may need to add one or more D8132 Battery Charger/
Power Supply Modules for the number of keypads you want
to use. Figure 10 shows the D8132 powering keypads in a
stand-alone configuration.
For UL certificated accounts, use a UL listed power supply.
The D8132 is not UL listed as a stand-alone power supply
for fire and burglary applications.
D2212 and D8132 (or other power supply) must share
COMMON: Note that Figure 10 shows the common from the
D8132 module connected to both the keypads' common and
terminal 10 on the panel.
A stand-alone power supply powering any device connected
to the panel must also be connected to terminal 10 on the
panel.
Do not connect the stand-alone power supply to
earth ground.
Telephone
Dialing Format
The panel can be programmed to use DTMF or pulse
dialing. See
Phone Parameters in the D2212 Program Entry
Guide.
Communication Failure
After 5 attempts to reach the receiver (10 attempts if two
phone number are programmed), the panel goes into
communication failure. The panel clears any reports in its
phone buffer. The panel sounds a tone at the keypad
indicating trouble.
Pressing the Clear key silences the tone. When
communication restores (a report is acknowledged by the
receiver), the keypad returns to normal operation.
Ground Start
Some telephone systems require a momentary ground input
to initiate dial tone. To interface with a ground start system,
connect a D133/D134 relay as shown in Figure 11.
See
RELAYS in the D2212 Program Entry Guide for
instructions on programming the external relay output for
Ground Start.
Terminal 3 on the panel must be connected to an earth
ground reference.
Warning: You cannot use ground start phone systems for
fire or combined fire burglary systems.
