Alarm output
Output specification:
Open collector output (exter-
nal max. applied voltage: 16 V DC)
OFF:

ON:
Output voltage 1 V DC or less (max. drive
current: 100 mA)
Color/black-and-white input
Input specification:
No-voltage make contact
input (3 to 5 V DC, internally pulled up)
Color:
Open or 3 to 5 V DC
Black and white:
Make contact with GND
(required drive current: 0.2 mA or more)
* When color input or black-and-white input is
