Operating and Installation Instructions
Step 4: Hush® Control Feature
The Hush® feature has the capability of temporarily desensitiz- ing the smoke alarm circuit for approximately 10 minutes. This feature is to be used only when a known alarm condition, such as smoke from cooking, activates the alarm. You can put your Smoke/CO Alarm in Hush® mode by pushing the test/reset but- ton. The unit will give a voice message "Hush mode activat- ed." If the smoke is not too dense, the alarm will silence immediately and the green LED light will flash every 2 seconds for approximately 10 minutes. This indicates that the smoke alarm is in a temporarily desensitized condition. Your Smoke/CO Alarm will automatically reset after approximately 10 minutes. When the unit returns to normal operation after being in Hush® mode the alarm will sound if smoke is still pres- ent. The Hush® feature can be used repeatedly until the air has been cleared of the condition causing the alarm. While the unit is in Hush® mode, pushing the test/reset button on the alarm will also end the Hush® period. The unit will give a voice message "Hush mode cancelled."
NOTE: DENSE SMOKE WILL OVERRIDE THE HUSH® CON- TROL FEATURE AND SOUND A CONTINUOUS ALARM.
CAUTION: BEFORE USING THE ALARM HUSH® FEATURE, IDENTIFY THE SOURCE OF THE SMOKE AND BE CERTAIN A SAFE CONDITION EXISTS.
Step 5: Peak Level Memory
if the green LED is blinking once every 16 seconds, the unit has detected a hazardous condition. If the CO sensor has detected a CO level of 100 PPM or higher since last reset, it will be recorded by the Peak Level Memory function. To access the Peak Level Memory press the test/reset button. If a reading of 100 PPM or higher has been recorded the unit will give a voice message "Caution, Carbon Monoxide previously detected." If you’ve been away from home this feature allows you to check if there was a CO reading of 100 PPM, or higher, during your absence. Pushing the test/reset button resets the memory. It’s also reset when the batteries are removed. There is no voice message associated with peak level due to smoke. When the test/reset button is pushed, the unit exhibits a normal PTT if the peak level is due to smoke.
