RE46C127
CMOS Ionization Smoke Detector ASIC with Interconnect and Timer Mode
Product Specification
Typical Single Button Application
R&E International
Figure 3
Notes:
Select R5 and R6 for the correct level to test the ion chamber. The voltage level on pin 1 (TSTART) must
be greater than the VIH level to initiate the timer. Pin 1 has an internal 180K nominal pull down which
must be considered.
Select R9 to reduce sensitivity during the timer mode.
R3, R4 and C1 are typical values and may be adjusted to maximize sound pressure.
C2 should be located as close as possible to the device power pins.
Route the pin 8 PC board trace away from pin 7 to avoid coupling.
