AC Input
Connect the appropriate UL Class II transformer using 18 gauge minimum 2
conductor wire. Do not exceed 50 feet. Use a 16.5 VAC 35 VA transformer or an
optional 16.5 VAC 20 VA transformer.
CAUTION: Do not short the terminals of the transformer together. This
causes the internal fuse to blow. The transformer must be connected to a
120 VAC, 24-hour outlet not controlled by a switch other than an approved
over-current protection device.
3
Switched Negative
(-) Current limited 100 mA terminal. Negative connection for 4-wire smoke
detectors, glass break detectors, and devices requiring resettable power.
4
Auxiliary Power
(+)12 VDC 500 mA continuous power. Overcurrent protected at 1.35 amps
(PTC4). Used for powering motion detectors, 4-wire smoke detectors, glass
break detectors, and other accessories.
CAUTION: Use terminals 4 and 10 when calculating total current drain.
5
Supervised Bell Output
(+)12 VDC. Combined alarm current should not exceed 1.5 amps. Overcurrent
protected at 1.85 amps (PTC2). A 1500 Ohm EOL resistor (CR854) must be con-
nected between terminals 5 and 7; otherwise a bell output fault will occur.
6
Two Wire Smoke (Zone 30)
(+)12VDC of two-wire smoke detectors connected to this terminal. A 1500
(power-limited)
Ohm EOL resistor (CR854) must be connected between terminals 6 and 7
regardless of whether a two-wire smoke detector is used or not. The maximum
series resistance is 60 Ohms.

Common Negative
BLACK WIRE - (-)12 VDC. Negative connection for Control Stations, zone
expander, printer interface, RF Gateway, ODMs, 2-wire smoke detectors,
motion detectors, and other devices.

Local Data Bus In (A)
GREEN WIRE - Connection for Control Stations, zone expander, printer
interface, RF Gateway and ODMs. Use 22 guage wire up to 1000 ft. Use 18
guage wire up to 2000 ft.
9
Local Data Bus Out (B)
WHITE WIRE - Connection for Control Stations, zone expander, printer
interface, RF Gateway and ODMs. Use 22 guage wire up to 1000 ft. Use 18
guage wire up to 2000 ft.
10
Control Station Power
RED WIRE - (+)12 VDC 500 mA continuous power connection for control
stations, zone expander, printer interface, RF Gateway and ODMs. Overcurrent
protected at 1.35 amps (PTC4).
CAUTION: Use terminals 4 and 10 when calculating total current drain.

FUNCTION
DESCRIPTION
ZX400/ZX410 Terminal Descriptions
Each loop requires a 1500 Ohm end-of-line resistor (P/N CR854) for the primary
zone, and an 825 Ohm end-of-line resistor (P/N CR853) for the secondary zone.
A common negative is shared among all zones. The need for end-of-line resistors
may be eliminated on all Burglar defined zones through programming. See
Figure 1 for “2 in 1” Zoning™ wiring examples.
