Connecting the Notification Appliance to the Wireless Input/
Output unit
To Mount the Notification Appliance to the Wireless Input/Output unit Enclosure
1. Wire a 3.9 k
Ω
end of line resistor (EOL) to ensure that the Wireless Input/Output unit
properly supervises the circuit. Notification appliance must be mounted on WIO or with
conduit otherwise (this connection shall not be greater than 6.1 metres and use an
extension ring for proper mechanical connection).
Figure 15 shows a generic notification appliance mounting plate. Refer to the
manufacturer’s documentation for the appliance’s specific mounting and wiring
requirements.

2. Wire the appliance mounting plate’s electrical contact screws to the right terminals on
the Wireless Input/Output unit as shown in Figure 16.
3. Screw the appliance mounting plate to the front of the Wireless Input/Output unit using
whichever mounting plate screw holes fit the 4 11/16” diagonal separation screw mounts
of the WIO unit, as shown in Figure 17.
Note:
Use wire lengths that will fit into the cavity behind the Wireless Input/Output unit
plugs, DIP switches, and USB terminal (22 AWG 6 cm length).
