I/O.
A connection is provided at pin 2 to
allow multiple smoke detectors to be
commoned. If any single unit detects smoke
(I/O is driven high), all connected units will
sound their associated horns after a nominal
3 second delay. The LED is suppressed
when an alarm is signaled from an intercon-
nected unit.
Testing.
On power up, all internal counters
are reset. Internal test circuitry allows for low
battery check by holding pins 8 and 12 low
during power up, then reducing V
DD
and
monitoring HORN
1
(pin 10). All functional
tests can be accelerated by driving pin 12
with a 2 kHz square wave. The 10 ms strobe
period must be maintained for proper opera-
tion of the comparator circuitry.
NOTE 1: An external resistor divider is used to adjust sensitivity for the
particular smoke chamber.
NOTE 2: A resistor to ground or V
may be added to this pin to modify
low battery voltage threshold.
