CALIBRATION
To facilitate checking the sensitivity and calibrating smoke
detectors, the MC145010 can be placed in a calibration
mode. In this mode, certain device pins are controlled/
reconfigured as shown in Table 5. To place the part in the
calibration mode, pin 16 (Test) must be pulled below the VSS
pin with 100
A continuously drawn out of the pin for at least
one cycle on the OSC pin. To exit this mode, the Test pin is
floated for at least one OSC cycle.
In the calibration mode, the IRED pulse happens at every
clock cycle and strobe is always on (active low). Also, Low
Battery and supervisory tests are disabled in this mode.

!Values for R4, R5, and C6 may differ depending on type of piezoelectric horn used.
* C2 and R13 are used for coarse sensitivity adjustment. Typical values are shown.
R9 is for fine sensitivity adjustment (optional). If fixed resistors are used, R8 = 12 k, R10 is 5.6 k to 10 k, and R9 is eliminated.
When R9 is used, noise pickup is increased due to antenna effects. Shielding may be required.
**C4 should be 22
F if B1 is a carbon battery. C4 could be reduced to 1 F when an alkaline battery is used.
