V. TERMINAL DESCRIPTIONS
TERMINAL DESCRIPTION
R1
House Telephone Ring (Grey).
R
Telephone Ring (Red).
T
Telephone Tip (Green).
T1
House Telephone Tip (Brown).
EARTH
Earth Ground. Connect to a cold water pipe or a 6 to 10 foot driven rod.
AC
AC input. Connect to a 16.5V 40 or 50 VA Class ll U.L. approved transformer.
BELL + & BELL
-
If used as a siren output (default), the speaker rating should be 15 watt at 8 or 16 ohm, or 30/40 watt at 4, 8,
or 16 ohms. If voltage output is selected in location 37, this output becomes voltage output, 12VDC, 1 Amp
maximum load. NOTE: A 3.3K Ω resistor may be required across the bell terminals when a 12 VDC
siren is used. If no resistor is used, you may experience voltage leakage into the siren, which will
cause these devices to output a small signal.
DATA
Connect to the data terminal on the keypads and the expanders. Maximum number of devices is 16 keypads
+ 3 other devices. See AMaximum Wire Run@ chart below.
COM
Connect to the Common terminal on the keypads and the expanders.
POS
Connect to the POS terminal on the keypads and the expanders. Individually, this terminal is limited to 1
Amp. Combined, this terminal and AUX PWR + are limited to 2 amps total current.
COM
Connect negative wire of powered devices such as motion detectors and smoke detectors.
AUX +
Connect positive wire of all powered devices except smoke detectors and keypads. Individually, this terminal
is limited to 1 Amp. Combined, this terminal and KP POS are limited to 2 amps total current.
ZONE 6
Connect to one side of zone 6 loop. Connect the other side to com terminal. Open or short causes alarm.
Only Zone 6 can used for a two-wire smoke detector, connected with a 680 Ω E.O.L. resistor. Refer to the
wiring diagram. Program location 37, segment 6, option 1. Only zone 6 can be a two-wire zone.
COM
Common (-) terminal for zones 5 & 6. (See the wiring diagram for examples.)
ZONE 5
Connect to one side of zone 5 loop. Connect the other side to COM terminal. Open or short causes alarm.
ZONES 1- 4
Connect as described for zones 5 & 6.
AUXOUT 4
(SMOKE +)
Smoke detector power 12VDC (for those jurisdictions which allow the Priority zone to be used with smoke
detectors.) Current limited to 250mA when output is positive and 250FA when output is negative. This output
defaults to Smoke Power, but can be re-configured. Zone 7 may be used for a 2-wire smoke detector
using a 680 ohm EOL resistor.
AUXOUT 1- 3
Connect negative lead of low current device [relay, LED (install 1KΩ resistor in series with LED), etc.].
Connect positive lead of device to COM. Current is limited to 250mA when output is negative, and 250FA
when output is positive.
NETWORX KEYPAD MAXIMUM WIRE RUN
(Note: These numbers are for one keypad at the end of the wire. When connecting more than one keypad to the end of the wire, a
higher gauge wire will be required.)
