Note: Horn Modulation Not Self–Completing
Low = Disable
High = Enable
(Suppressed LED for Remote Only)
NOTES:
1. Horn modulation is self–completing. When going from smoke to no smoke, the alarm condition will terminate only when horn is off.
2. Comparators are strobed on once per clock cycle (1.67 s for no smoke, 40 ms for smoke).
3. Low battery comparator information is latched only during LED pulse.
4.
100 mV p–p swing.
