1.6.2.2 Automatic BIT

The detector automatically performs a BIT every 15 minutes. A successful

BIT sequence does not activate any indicator.

All outputs of BIT results will function as described in Table 9 and Table 10,

and the BIT will be automatically executed every 1 minute.

This continues until a successful BIT occurs, when the detector resumes

normal operation.
