Keypad Connections
For Keypad wiring instructions, refer to the DV8000 Wiring Diagram at the end of this manual.
Connect the red, black, green and yellow keypad leads to the RED, BLK, GRN and YEL Keypad terminals on the
control panel using four conductor (quad) telephone wire. Up to four Keypads may be connected to the DV8000;
wire additional Keypads in parallel to the RED, BLK, YEL GRN Keypad terminals on the panel. Note that the
Keypad’s power is supplied through the auxiliary fuse.
Power Terminals: AC
Use a 16.5 VAC transformer rated to 37VA to supply AC power to the DV8000. The transformer should be
connected to an unswitched outlet. If AC failure occurs, it will be displayed as a trouble condition on the Keypad;
refer to Keypad Commands [
∗
][0][2] Displaying Trouble Conditions. An AC Failure Trouble can also be
transmitted to the monitoring station depending on the Trouble Type programmed in Mode 20 Address [232].
Auxiliary Power Terminal: VAUX and GND
The auxiliary power supply can be used to power motion detectors and other devices requiring 12VDC. A
maximum of 0.5A is available from the VAUX (positive) and GND (negative) terminals when the DV8000 is used
with one Keypad. For each additional Keypad, the auxiliary supply rating must be reduced by 36mA. The auxiliary
supply is fuse protected at 1 amp. A failure of the auxiliary fuse will generate a trouble transmission.
Bell / Siren Terminals: BELL+ and BELL-
The BELL terminals are used to power bells or other audible warning devices requiring a steady output voltage on
alarm. The bell output is fuse protected at 2 amps. When connecting sirens or speakers with a siren driver
already built-in, be sure to observe the correct polarity. Connect the positive lead to the BELL+ terminal and the
negative lead to the BELL- terminal. If the control panel’s built-in siren driver is used, output at the BELL terminals
will be non-polarized.
Note that the alarm output is pulsed (2 seconds on, 2 seconds off) when an alarm is created by the Fire Zone or by
pressing the Keypad’s dedicated fire key.
If no siren or bell is used, connect a 1000 ohm 1/2 watt resistor between the BELL+ and BELL- terminals.
Programmable Output Terminals: PGM OUT 1 and PGM OUT 2
The operation of the PGM OUT 1 Terminal is determined by the value programmed in Mode 22 Address [035]. The
operation of the PGM OUT 2 Terminal is determined by the value programmed in Mode 22 Address [036]. Refer to
Appendix B Quick Reference Guide for a description of the programmable options for the PGM outputs.
PGM OUT 1 and PGM OUT 2 are transistor switched to ground through a 150 ohm current limiting resistor. A
relay, buzzer or other DC-operated device may be connected between the VAUX terminal and the PGM OUT 1 or
PGM OUT 2 terminals on the main board.
Programmable Output Terminal: PGM OUT 3
The Switched Auxiliary Supply can be switched on or off momentarily from the Keypad; refer to Mode 04 and Mode
05 in the Instruction Manual. The operation of the Switched Auxiliary Supply is determined by the value
programmed at Mode 22 Address [037]. Refer to the Quick Reference Guide for a description of the
programmable options.
The PGM OUT3 terminal is positive and the GND terminal is negative. The Switched Auxiliary Supply is
electronically current limited to 25mA, and will not cause a fuse to open if switched to negative.
KEY Input Terminal: AUXIN and Key Arming
The AUXIN input is a standard normally-open zone. An alarm on this input is created when the resistance of the
loop goes higher (an open circuit) or lower (a short circuit) than normal. Refer to the Programming Worksheets,
Mode 20 Addresses [429] for programming the alarm code for this input.
The Auxiliary input is intended to be used as a burglary zone or key switch input only. The AUXIN terminal can be
used as a momentary or maintained keyswitch arming and disarming input.
FIRE Zone Input Terminals
The FIRE zone is a Class A1 Fire Zone. On alarm (fire loop shorted), the activation delay will begin to count down.
After the delay has expired, the bell output will pulse and the alarm will be transmitted to the monitoring station.
The delay for an alarm on this loop is programmed in Mode 22 at Addresses [025], [026] and [028]. If the zone
goes open, a trouble alarm will be generated.
Ground Fault
A short circuit (100µA) between earth ground and system ground will cause a trouble condition. The Ground Fault
Trouble Reporting Code is programmed in Mode 20 Address [444].
