ADDITIONAL APPLICATIONS
Energising a relay with detection day or night
providing volt free contacts, Suggested relay
12VDC 470 ohms minimum coil resistance.
Energising a relay with detection at night for one
minute longer than last detection.
Driving a low power piezo sounder directly from
Opal XL.
The piezp will sound briey every time a
detection takes place day or night.
