EXTERNAL CONNECTIONS
ALARM (A) IN/ ALARM B IN
You can connect two devices including an alarm
switch with a resistance of 1 kohm or less or a door
sensor. Connect pin
q
or
u
to pin
!5
(ground)
through the switches.
Notes:
• Do not apply a voltage to pin
q
,
u
or
!5
.
• If an alarm is input to the ALARM (A) IN terminal
when an alarm is being input to ALARM B IN, the
input at ALARM (A) IN has priority. However, an
alarm at ALARM B IN is not accepted when an
alarm is being input to ALARM (A) IN.
• The recording conditions are different for the
alarms input to the ALARM (A) IN and ALARM B
IN terminals. See page 19 for details.
ALARM OUT
Approx. 12V is applied to pin
w
during an alarm
recording.
Notes:
• When you have selected “PULSE” in the “ALARM
OUT” menu in the ALARM display, approx. 12V
pulses will be applied to the output after the
alarm recording ends.
• When you have selected “DURATION” in the
“ALARM OUT” menu in the ALARM display, no
voltage is applied after the alarm recording ends.
• The output impedance is approx. 100 ohm.
ONE SHOT IN
One shot recording is possible when pin
e
is
shorted to pin
!5
.
Note: Do not apply a voltage to pin
e
or
!5
.
TAPE END OUT
Approx. 12V is applied to pin
r
when the tape
reaches the end.
Notes:
• This does not operate when you have selected
“REWIND, RE-REC” in the “RECYCLE FUNC-
TIONS” menu in the ALARM display or you have
selected “REWIND, STOP IF ALARM” and no
alarm recording has been made.
• The output impedance is approx. 100 ohm.
