battery, respectively. Pin 1 = VDD for smoke and Pin 4 = VDD
for low battery. In this mode and during the 10 ms power
strobe, chip current rises to approximately 50
μA.
Led Pulse
The 9-volt battery level is checked every 40 seconds
during the LED pulse. The battery is loaded via a 10 mA
pulse for 11.6 ms. If the LED is not used, it should be replaced
with an equivalent resistor such that the battery loading
remains at 10 mA.
Hysteresis
When smoke is detected, the resistor/divider network that
sets sensitivity is altered to increase sensitivity. This yields
approximately 100 mV of hysteresis and reduces false
triggering.

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 once per cycle (1.65 sec for no smoke, 40 msec for smoke).
