Description
Open collector output
Minimum delay among subsequent ignition 100msec.
Protected against reverse polarity
WORKING
Once alarm state is on, the control unit activates the open collector
output (pin 8) according to the following timing diagram:
If during 10-sec time alarm state goes off for at least 0,5 sec,
the output is deactivated. If alarm state persists, the output
is reactivated without delay:
INPUT A (PIN 4) | INPUT B (PIN 5) | INPUT C (PIN 6) | INPUT D (PIN 7) | ALARM STATE |
