Electrical Connection
National Electrical Code as well as local codes must be adhered to in the
installation of these models. All electrical wiring must be routed through
approved conduit and fittings as specified.
WARNING
Property damage, serious injury, or death could occur if
independent conductors are terminated together. NFPA 72
requires that the wires be terminated independently to provide
electrical supervision of the connection.
Property damage, serious injury, or death could occur if the
housing is not closed properly.
Tone Card Installation
1. See figure 2. Connect the device’s red (+) leads to the power source
positive (+) lead. Connect the device’s black (-) leads to the power
source negative (-) lead.
2. Plug the desired tone card into the socket as shown in figure 3.
3. To ensure a proper seal, be sure that the neoprene rubber cover
gasket is properly seated in the housing groove and reinstall the
housing cover.
PTCK Connector Kit Installation
WARNING
Property damage, serious injury, or death could occur if
independent conductors are terminated together; both wires of
the same polarity must be used as two separate connections.
NFPA 72 requires that the wires be terminated independently
to provide electrical supervision of the connection, for both the
24 Vdc speaker power and 25 VRMS or 70 VRMS audio lines.
1. See figure 2. Connect the device’s red (+) leads to the power source
positive (+) lead. Connect the device’s black (-) leads to the power
source negative (-) lead.
2. Plug the desired PTCK connector card (purchased separately) into the
socket as shown in figure 3.
3. Connect the white leads from the connector card to the audio input
and outputs.
4. To ensure a proper seal, be sure that the neoprene rubber cover
gasket is properly seated in the housing groove and reinstall the
housing cover.
NOTE
Check with authority having jurisdiction for proper application
of EOL resistor and power supervision relay required (see
