Power On Initial
The PIR signal amplifier requires a warm up period after power-
on. The input should be disabled during this period, mean-
while, TRIAC and RELAY output will hold on in order to
indicator system has been power on.
In the AUTO mode within the first 10 seconds of power-on
initialization, the chip allows override control to enter the
quickly check mode. After 40 seconds of the initial time the
chip allows override control between ON and AUTO. It will
remain in the warm up period if the total initial time has not
elapsed after returning to AUTO.
In case that the ZC signal disappears more than 3 seconds, the
chip will restart the initialization operation.
MODE
The operation modes of PT8A2612 is shown in the following
table.
Override function
By effective ZC signal switching (switch OFF/ON twice within
3 seconds), the chip provides the following additional func-
tions:
Quick check mode: Within 10 seconds after power-on, effec-
tive ZC switching will force the chip to enter the quickly check
mode. During the mode, the outputs will be active for duration
of 2 seconds each time a valid PIR trigger signal is received. If
a time interval exceeds 32 seconds without a valid trigger
input, the chip will return to the AUTO mode automatically.

TRIAC output can soft start when activated by a valid PIR input trigger signal. TRIAC output
can also soft stop when timing is elapsing. When working in the AUTO mode, the chip
allows override control by switching the ZC signal too.
