TERMINAL DESCRIPTION
TERMINAL DESCRIPTION
R1 House Telephone Ring.
R Telephone Ring.
T Telephone Tip.
T1 House Telephone Tip.
AC AC input. Connect to a 16.5V 35VA CE approved transformer.
EARTH Earth Ground.
AUX 1
Connect negative lead of low current device [relay, LED (install 1K Ω resistor in
series with LED), etc.]. Connect positive lead of device to KEYPAD +. Current is
limited to 250 mA when output is negative, and 250 µA when output is positive.
SIREN
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 3.3KW 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.
COM Connect the negative wire of powered devices such as motion and smoke detectors.
SMOKE+ Smoke detector power 12VDC, 250 mA maximum.
AUX 2
Connect negative lead of low current device [relay, LED (install 1K Ω resistor in
series with LED), etc.]. Connect positive lead of device to KEYPAD +. Current is
limited to 250 mA when output is negative, and 250µA when output is positive.
KP DATA
Connect to the data terminal on the keypads and the expanders. Maximum wire run
is 800 m with 2 mm² wire. The minimum wire sizes at 75, 150, 300 and 600 m are
0.12, 0.33, 0.83 and 1.3 mm² respectively. These numbers are for one keypad at the
end of the wire and a voltage drop of max. 2 Volts. When connecting more than one
keypad to the end of the wire, a higher gauge wire will be required. The maximum
number of devices are max. 8 keypads and max 1 expander.
COM
AUX PWR -
Connect to the Common terminal on the keypads, expanders, and other power
devices.
POS
AUX PWR +
Connect to the Positive terminal on the keypads, expanders, and other power
devices. This terminal is limited to 1 amp total current.
ZONE 4
Connect to one side of zone 4 loop. Connect the other side to the COM terminal.
Open or short causes alarm.
COM Common (-) terminal for zones 3 & 4.
ZONE 3
Connect to one side of zone 3 loop. Connect the other side to COM terminal. Open or
short causes alarm.
ZONE 2
Connect to one side of zone 2 loop. Connect the other side to the COM terminal.
Open or short causes alarm.
COM Common (-) terminal for zones 1 & 2.
ZONE 1
Connect to one side of zone 1 loop. Connect the other side to COM terminal. Open or
short causes alarm.
