• ALARMOUT,AUXOUT
Output specification: Open collector output (maximum applied voltage: 20 V DC)
Open: 4 V - 5 V DC by internal pull-up
Close: Output voltage 1 V DC or less (50 mA or less)
• ALARMIN
Input specification: No-voltage make contact input (4 V - 5 V DC, internally pulled up)
OFF: Open or 4 V - 5 V DC
ON: Make contact with GND (required drive current: 1 mA or more)
b Connect a LAN cable (category 5 or better,
straight, STP*) to the network connector.
* PAL models only
n Connect the power supply.
Important:
• The 12 V DC power supply shall be insulated
from the commercial AC power.
When using 12 V DC power supply
q Loosen the screw of the power cord plug
(accessory).
w Connect the cable of the 12 V DC power sup-
ply* to the power cord plug.
Strip 3 mm - 7 mm {1/8" - 9/32"} from the end
of the wire, and twist the stripped part of the
wire sufficiently to avoid short circuit.
Specification of cable (wire):
16 AWG - 24 AWG, Single core, twisted
• Check whether the stripped part of the wire is
not exposed and is securely connected.
e Tighten the screw of the power cord plug.
r Connect the power cord plug to the 12 V DC
power supply terminal.
* FOR UL LISTED MODEL(S), ONLY CONNECT
12 V DC CLASS 2 POWER SUPPLY.
