itors cause the station control module to write to these
bits which, in tum, send the alarm tones.
NOTE
If the four internal alarm bits of address 12
are activated by the DMP, or some other
control module connected
to the MUX-
bus, then the alarm beeps will be activated,
but the actual internal alarm condition will
not be simulated.
For example, if the PA
Fail alarm bit (RW2 PA) were to be acti-
vated, two alarm beeps would be sent, but
the PA itself would not be forced to dekey.
The station control module code plug contains information
which determines whether an internal alarm gets written to
the MUXbus, and also if all of the reverse "wild card"
MUXbus bits will be enabled to activate alarm tones. Thus,
all 8 bits can be configured as external alarm inputs, if de-
sired. The maximum number of internal alarms is four.

RW4
OVG (Reverse

Bit 4 -
Bauery Overvol-
taze) 12, D3
The RW4 OVG bit is the battery overvoltage internal sta-
tion alarm parameter, and is activated by the station control
module. RW4 OVG is active when the station battery char-
ger power supply indicates that the external (customer
supplied) station emergency batteries
are providing too
much voltage (e.g., are overcharged).
RW3
SYN (Reverse
"Wild
Card"
Bit
3 - Synthesizer
Un-
lock) 12, D2
The RW3 SYN bit is the transmit or primary receiver syn-
thesizer unlocked internal station alarm parameter, and is
activated by the station control module. RW3 SYN is active
when either the transmit, primary receive, or both synthesiz-
ers are unlocked.
RW2
PA (Reverse
"Wild
Card"
Bit 2 -
PA Rlil)
12, Dl
The RW2 PA bit is the rf power amplifier fail internal station
alarm parameter,
and is activated by the station control
module. RW2 PA is active when the rf power amplifier has

failed. A successful keyup or a station control module reset
is required to clear the alarm. The alarm may be active when
the transmitter is de-keyed, due to a prior failure. PA Fail
means that one or both of the station control module PA
status lines (pA On or PA Full Power) are inactive
30-45
msec after the start of a keyup, or for
30-45
msec continu-
ously during keyup, thereafter.
RW2 PA is not activated by
the station control module if the PA is not keyed at full pow-
er due to the station control module personality EPROM
rf power cut option. If the station control module service
jumper (JUB01) is installed, the station control module will
activate RW2 PA regardless of the PA status lines. This is
a reminder that the rf power amplifier is operating in a non-
standard manner.
RWl BAT
(Reverse
"Wild
Card"
Bit
1 - Bauery Revert) 12,
DO
This bit is the battery revert internal station alarm parame-
ter activated by the station control module. RWI BAT is ac-
tive when the station battery charger power supply indicates
that the station has lost ac power and has switched to emer-
gency battery backup. RWI BAT becomes inactive as soon
as proper ac power is restored to the station.

Reserved for those reverse "wild card" applications which
provide an interface between external station inputs and the
MUXbus. These parameters
can also provide additional
alarm input capability thru information contained in the sta-

identified as alarm inputs.

Use of the Forward "Wild Card" bits (up to 8 bits on ad-
dresses 14 & 15) require the "wild card" module (four out-
puts per card) which resides in the Control Option Tray. Re-
mote wireline control activates these bits. The "wild card"
control module responds by activating a relay closure or an
open collector output. These closures and/or outputs can
then be used to control equipment external to the station.
