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 25, 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 Ω, or 30/40 watt at 4, 8, or 16
Ω. If voltage output is selected in location 37, this output becomes voltage output, 12VDC, 1 Amp maximum load.
NOTE: A 3.3K 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.
KP DATA
Connect to the data terminal on the keypads and the expanders. When connecting more than one keypad to the
end of the wire, a higher gauge wire will be required. Maximum number of devices is 8 keypads + 3 other devices.
KP COM Connect to the Common terminal on the keypads and the expanders.
KP POS
Connect to the Positive terminal on the keypads and the expanders. This terminal and AUX PWR + are limited to 1
amp total current when added together.
COM Connect negative wire of powered devices such as motion detectors and smoke detectors.
AUX PWR+
Connect positive wire of all powered devices except smoke detectors and keypads. This terminal and KP POS are
limited to 1 amp total current when added together.
ZONE 6 Connect to one side of zone 6 loop. Connect the other side to com terminal. Open or short causes alarm.
COM Common (-) terminal for zones 5 & 6.
ZONE 5 Connect to one side of zone 5 loop. Connect the other side to COM terminal. Open or short causes alarm.
ZONE 4 -
ZONE 1
Connect as described for zones 5 & 6. (See the wiring diagram for examples.)
AUX OUT 4
SMOKE +
(ZONE 7)
Smoke detector power 12VDC (for those jurisdictions that allow the Priority zone to be used with smoke detectors).
Current limited to 250 mA when output is positive and 250 microamps 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 Ω E.O.L. resistor. W3 must be removed for 2-wire smoke detector loop. For use as Aux Out 4, W2
must be set. The 2-wire smoke loop cannot be enabled if Zone Doubling is used.
AUX OUT 3 -
AUX OUT 1
Connect negative lead of low current device [relay, LED (install 1K resistor in series with LED), etc.]. Connect
positive lead of device to AUX PWR +. Current limited to 250 microamps maximum when output is positive and
250 mA when output is negative.
NETWORX KEYPAD WIRING REQUIREMENTS
(NOTE: These numbers are for one keypad at the end of the wire. When connecting more than one device to the end
of the wire, a higher gauge wire will be required.)
