optional push button.
F1/F2 Select (Optional) Latched or momentary pulsed N.O. or N.C. relay contacts.
Intercom (Optional) Optional momentary push button activated circuit that allows audio transmissions
between local extensions with out keying the radio. May be used on or off-hook.
Installation Considerations
The LE series local extension will work with any radio
system that will accept a 2 mVRMS to 565 mVRMS mic
audio input level and provide an 88 mVRMS to 880
mVRMS receive audio output level.
If the radio is going to be used as a control point, the receive
audio should be taken from a point after the squelch circuit
that is unaffected by the radio's volume control.
If the radio is not going to be used as a control point,
speaker output may be used by setting the radio's volume
control for a level that falls into the above range.
The LE series requires 12 to 16 VDC @ 175 mA. This may
be supplied from a central source at the radio site using a
conductor in the hook-up cable or by using the -WP option.
18 to 22 gauge multi-conductor cabling is recommended
with the number of conductors determined by the application
and options installed.
A minimum configuration will use 6 conductors, a maximum
will use 12.
Options
-M Push button CTCSS disable. (Monitor)
-I Push button intercom. May be used on or off-hook
to communicate with other local extensions with out
keying radio.
-2F Push button selectable momentary or latching
relay output for frequency selection. LED indicators show
selected channel.
-WP Wall plug-in transformer power pack.
-WM Wall mount kit. Includes snap on bracket for
remote and wall mount plate and hardware.
-DE 12 key DTMF encoder.
