Installation
Remove the plastic cap from the threaded throat of the driver and screw
the driver into the horn until firmly seated
Install the horn/driver assembly in intended location, referring to the
instructions provided with the horn.
Remove the three screws from the rear of the driver housing and open the
housing for access to the wiring.
Loosen the gland nut in the side of the driver housing enough to admit the
loudspeaker wire/cable. Alternately, a 1/2-inch conduit fitting can be
substituted for the gland nut. However, the sealing washer must be retained.
For the ID30CT, connect the loudspeaker wires to the “com” terminal and
the appropriate line terminal (25 V or 70 V). For the ID30C-8/-16, connect
to the black and white loudspeaker wire using wire nuts.
Tighten the gland nut securely and reassemble the rear housing by replacing
the screws and tightening securely.
Transformer Model (1829T)
A transformer and power-selector switch are installed in the base of the
housing. Color coding for the transformer is listed in Table II. Transformer
wiring with respect to Table II is illustrated by Figure 5.
Low-Frequency Driver Protection
When frequencies below the low-frequency cutoff for the horn assembly
are fed to the driver, excessive current may be drawn by the driver. For
protection of driver, amplifier, and transformer (if driver with built-in

shown are for 200 Hz. Values for other frequencies can be determined by
using the formula:
