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.
