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.

Electrical Specifications of Alarm Input
Terminals
(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
