TB1-10/11 Channel 2 Auxiliary Input
The signal source connected to this input is switched to the channel 2
pre-amp out terminals upon activation of the CHANNEL 2 TAPE
switch or 4121 on the front panel, or mode 2. Input impedance is
600
Ω
. These terminals may be used to connect a RAMM, MVM, or
CDR-3 module.
Note:
MVM inputs do not require DAMP-R.
TB1-12/13 Channel 1 Auxiliary Input
The signal source connected to this input is switched to the channel 1
pre-amp out terminals upon activation of the CHANNEL 1 TAPE
switch on the front panel, or 4119, or mode 2. Input impedance is
600
Ω
. These terminals may be used to connect a RAMM, MVM, or
CDR-3 module.
TB1-14/15 Channel 1 Auxiliary Supervision
Used to supervise a channel 1 auxiliary device. An open circuit
between terminals 14 and 15 generates a 4114 Channel 1 Auxiliary
trouble condition. Normal supervision requires 0K
Ω
resistor across
terminals.
TB1-16/17 Channel 2 Auxiliary Supervision
Used to supervise a channel 2 auxiliary device. An open circuit between
terminals 16 and 17 generates a 4115 Channel 2 Auxiliary trouble
condition. Normal supervision requires 0K
>
resistor across terminals.
TB1-18/19 Start Relay
Used to activate a RAMM module. Separately programmed with address
pp4103 (pp)=priority
TB1-20 (+) and TB1-21 (-) External Input
Activates FCCA when >18 VDC applied to terminals. Generates a SUP
OPEN 4122.
TB2-1 (+) and TB2-2 (-) Telephone Riser 1 TB2-4 (+) and
TB2-5 (-) Telephone Riser 2
Used for the fire fighter phone communications system. A maximum of 5
fire fighters telephones per riser may be off hook at any one time.
Connect telephone riser 1 or 2 to the "B" riser input terminals on the
CM1/2(N) motherboard or RZB12-6. Riser supervision is accomplished
using a URSM (P/N 130102) at the last remote panel that contains a
telephone circuit. Unused telephone risers must be terminated with a
10K
Ω
, 1/2 W EOL resistor.
Telephone branch circuit switching is controlled and annunciated via
RASP, SAN, or FCCS switch and annunciation panels.
