Philips LTC 3963/51 Manual De Usuario

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.

TAPE END RESET
The TAPE END OUT can be turned off when pin t is
shorted to pin !5.
Note:  Do not apply a voltage to pin t or !5.
