JVC TK-C215VP12U/E Manual De Usuario

(TK-C215VP12U/E only)
● To prevent penetration of noise in the internal 

circuitry, apply a non-voltage contact signal to 
the ALARM input terminal. Never apply a 
voltage.

● Apply an alarm signal for at least 200 ms. If it is 

shorter, it is not guaranteed that the signal will 
be recognized as an alarm signal.

● Under the alarm status (status when the metal 

contact is “make”), select the contact or 
connecting wire such that the maximum wire 
resistance between the ALARM IN and 
ALARM GND is within 150 

K.
