Figure 8: Connecting the J10 Connector
The J10 connector (jumper) determines the UO1 connection (behavior), which is
normally used for an external siren connection, as follows:
Positive (POS): When the J10 connector is placed on POS, the C terminal on UO1 receives
13.8V.
NOTE:
The maximum current for UO1 and the bell should not exceed 900mA.
Negative (NEG): When the J10 connector is placed on NEG, the C terminal on UO1 receives
COM.
If the J10 connector is placed only on 1 pin, the UO1 acts as a dry contact.
