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 function as described in Table 10 and Table 11,
and the BIT is automatically executed every 1 minute.
This sequence continues until a successful BIT occurs, when the detector
resumes normal operation.
