Level Adjustments
Transmit Level
The Transmit Level potentiometer, R34, adjusts the signal level from the handset or optional auxiliary
headset microphone to the page or party lines.
Receiver Volume
The Receiver Volume potentiometer, R5, adjusts the signal level to the handset receiver from the page or
party lines. It does not adjust the signal level to the optional auxiliary headset.
Speaker Volume
The Speaker Volume potentiometer, R91, adjusts the signal level to the speaker from the page line. The
default setting is 4 watts for an 8-ohm speaker and 2 watts for a 16-ohm speaker.
Warning – Maximum output power may exceed rated speaker wattage resulting in speaker damage.
Attach the Front Cover
After all adjustments have been completed, inspect and clean the machined flange joint surfaces of both
the cover and box. Surfaces must be smooth, free of nicks, scratches, dirt or any foreign particle build-up
that would prevent a proper seal. Surfaces must seat fully against each other to provide a proper
explosion-proof joint. Clean surfaces by wiping with a clean lint-free cloth.
Apply a light coat of Killark “LUBG” lubricant to flange surfaces and close the cover. Install and tighten
all cover bolts to 30 ft.-lbs. Make certain no cover bolts are omitted. Use only those bolts supplied with
the enclosure.
It may become necessary to re-terminate some or all of the enclosures in a system. If so, strip the wires
back to clean copper and connect only one wire to each connector to allow for easier future
troubleshooting.
N OTE : Refer to the Killark Installation, Operation, and Maintenance Data Sheet enclosed with the unit for
additional information.
Operation
For paging and subsequent party line conversation, the station operator lifts the handset, selects a free
party line using the five-position rotary selector switch (if equipped), and presses the handset pressbar or
headset page switch. The station operator pages the desired individual and designates the party line on
which that individual should respond. The individual then responds by approaching the nearest ICS
Page/Party
® station, selecting the appropriate party line and lifting the handset or connecting a headset.
Full-duplex communication can then be held on the party line without broadcasting over the speakers.
After the conversation is complete, all parties should place the handset back on hook.
N OTES : The ICS Page/Party
® station incorporates a noise-canceling microphone to reduce transmitted
ambient noise. This requires the user to place the microphone as close as possible to their mouth.
