Note 1 – See timing diagram for Horn Temporal Pattern

Note 2 – During the timer mode the LED Period is 10.5 seconds. The LED period will return to a 43 seconds at the conclusion of the timer

mode.

Note 3 - TPOSC and TON2 are 100% production tested. All other timing is guaranteed by functional testing.

Typical values are for design information and are not guaranteed.

Limits over the specified temperature range are not production tested and are based on characterization data.
