6 / 8 page MC14468 6 Motorola Sensor Device Data Figure 6. Timing Diagram Hysteresis (Internal) (Pin 13 ) (Pin 14) Detect Out (Pin 1) Low Battery (Internal) Sample (Internal) Smoke Horn (Pin 10 and 11) LED (Pin 5) Oscillator (Pin 12) Standby Smoke/No Low Battery Smoke/Low Battery No Smoke/ No Low Battery No Smoke/Low Battery 40 ms 10 ms 1.67 s 24 Clock Cycles (0.96 s) 24 Clock Cycles (40S) 24 Clock Cycles 6 Clock Suppressed Chirp Battery Test (Note 3) (Note 3) (Note 1) Cycles (10.0 s) Strobe Out (Pin 14) I/O (Pin 2) Output (Local) I/O (Pin 2) Input (Remote) LED Note: Horn Modulation Not Self–Completing Low = Disable High = Enable (Suppressed LED for Remote Only) 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 on once per clock cycle (1.67 s for no smoke, 40 ms for smoke). 3. Low battery comparator information is latched only during LED pulse. 4. X 100 mV p–p swing.
