Sample Smoke
Horn
IO (Pin 2) as Output
See Figure Below for Complete Horn Cycle
TIODLY1
Timing not same scale as above
Low Battery Warning Chirp
IO Charge Dump
TIOFILT
IO ( Pin 2) as Input
Horn Start of horn temporal pattern is not synchronized to an external alarm
TIODLY2
LED supressed in remote alarm mode
Horn pattern not self completing for external alarm,see timing below for complete horn cycle
Internal Clock
Notes:
1. Smoke is not sampled when the horn is active. Horn cycle is self completing in local alarm.
2. Low battery warning chirp is suppressed in local or remote alarm
3. IO Dump active only in local alarm, inactive if external alarm
