Photoelectric Smoke
Detector IC with I/O
sophisticated very-low-power analog and digital circuitry. The IC is used with an
infrared photoelectric chamber. Detection is accomplished by sensing scattered
light from minute smoke particles or other aerosols. When detection occurs, a
pulsating alarm is sounded via on-chip push-pull drivers and an external
piezoelectric transducer.
(photodiodes). Two external capacitors, C1 and C2, C1 being the larger, determine
the gain settings. Low gain is selected by the IC during most of the standby state.
Medium gain is selected during a local-smoke condition. High gain is used during
push button test. During standby, the special monitor circuit which periodically
checks for degraded chamber sensitivity uses high gain, also.
for common signaling. An on-chip current sink provides noise immunity when the I/
O is an input. A local-smoke condition activates the short-circuit-protected I/O
driver, thereby signaling remote smoke to the interconnected units. Additionally, the
I/O pin can be used to activate escape lights, enable auxiliary or remote alarms,
and/or initiate auto-dialers.
using a pulsed load current from the LED pin. The trip point is set using two external
resistors. The supply for the MC145010 can be a 9 V battery.
smoke condition. A pulsating audible alarm with no LED flash indicates a remote-
smoke condition. A beep or chirp occurring virtually simultaneously with an LED
flash indicates a low-supply condition. A beep occurring half-way between LED
flashes indicates degraded chamber sensitivity. A low-supply condition does not
affect the smoke detection capability if V
condition and degraded chamber sensitivity can be further distinguished by
performing a push button (chamber) test.
