4. Operation and Testing

from cooking, activates the alarm. The HUSH feature cannot be activat- ed unless the smoke alarm is sounding in the originating alarm mode. The smoke alarm is desensitized by pushing the “ TEST / HUSH” button on the smoke alarm cover. If the smoke is not too dense, the alarm will silence immediately. The green LED will blink once every 3 seconds while in hush. This indicates that the alarm is in a temporarily desensitized condition. The smoke alarm will automatically reset after approximately 8 minutes and sound the alarm if particles of combustion are still pres- ent. The “HUSH” feature can be used repeatedly until the air has been cleared of the condition causing the alarm. Pushing the Test / Hush but- ton on the alarm will end the hush period.

NOTE: DENSE SMOKE WILL OVERRIDE THE HUSH CONTROL FEA- TURE 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.

LED INDICATORS: This smoke alarm is equipped with red and green LED indicators. The green LED (when illuminated) indicates the presence of AC or battery backup power. The red LED operates in unison with the sounder during alarm and error mode conditions:

Standby Condition: The green LED will be lit continuously if AC power is present or flash every 30 seconds if powered by battery backup only.

Alarm Condition: When the alarm senses products of combustion and goes into alarm, the red LED will flash with the sounder and the green LED will flash once per second. The flashing red LED and pulsating alarm will continue until the air is cleared. WHEN UNITS ARE INTERCONNECT- ED, only the green LED of the alarm which senses the smoke or is being tested (the originating unit) will flash. All other units in the interconnect system will sound an alarm but their green LED’s will remain constat to indicate AC power or flash once every 30 seconds when on battery backup.

Alarm Memory: This smoke alarm is equipped with an alarm memory, which provides a visual indication of when an alarm has been activated. The green LED will flash once every 16 seconds to indicate the memory condition (AC powered and battery backup). The memory will remain activated until the button is pressed causing the alarm to rapidly beep 3 times and reset the alarm memory function. In an interconnected installa- tion only the memory of the originating alarm will be activated. If the bat- tery power is low due to insufficient charge, this feature is over ridden and the green LED will function to indicate either AC power is present or Battery backup operation

Hush® mode: The green LED will blink every 3 seconds, indicating the smoke alarm is in the Hush® mode.

4. Operation and Testing

Testing: Test by pushing the Test/Hush button on the cover. This will sound the alarm if the electronic circuitry and horn are working. In an interconnected installation all interconnected alarms should sound when the Test/Hush button on any of the interconnected alarm is pressed. After completing its test cycle the Green LED will be off for approximate- ly 30 seconds while the unit completes its self test.

If no alarm sounds, check the fuse or circuit breaker supplying power to the alarm circuit. Verify that the green LED is on. If the alarm still does not sound, the alarm may have defective batteries or other failure.

DO NOT use an open flame to test your alarm. You could damage the alarm or ignite combustible materials and start a structure fire.

TEST THE ALARM WEEKLY TO ENSURE PROPER OPERATION. Erratic or low sound coming from your alarm may indicate a defective alarm, and it should be returned for service (see section 12).

5. Nuisance Alarms

Smoke alarms are designed to minimize nuisance alarms. Cigarette smoke will not normally set off the alarm, unless the smoke is blown directly into the alarm. Combustion particles from cooking may set off the alarm if the alarm is located close to the cooking area. Large quanti- ties of combustible particles are generated from spills or when broiling. Using the fan on a range hood which vents to the outside (non-recircu- lating type) will also help remove these combustible products from the kitchen.

This model is equipped with a "Hush" feature that is extremely useful in a kitchen area or other areas prone to nuisance alarms. For more infor- mation, refer to section 4 OPERATION AND TESTING.

If the alarm does sound, check for fires first. If a fire is discovered, get out and call the fire department. If no fire is present, check to see if one of the reasons listed in section 2 may have caused the alarm.

CLEANING YOUR ALARM

YOUR ALARM SHOULD BE CLEANED AT LEAST ONCE A YEAR

To clean your alarm, remove it from the mounting bracket as outlined in the beginning of this section. You can clean the interior of your alarm (sensing chamber) by using compressed air or a vacuum cleaner hose and blowing or vacuuming through the openings around the perimeter of the alarm. The outside of the alarm can be wiped with a damp cloth. After cleaning, reinstall your alarm and test your alarm by using the Test/Hush button. If cleaning does not restore the alarm to normal oper- ation the alarm should be replaced.

This smoke alarm utilizes both photoelectric and ionization sensing methods, allowing it to detect different types of smoke more effectively. The photoelectric sensor is adept at sensing slow-burning fires, which produce larger smoke particles, such as those from smoldering furniture or electrical fires. The ionization sensor, on the other hand, quickly responds to fast-burning fires that generate smaller particles, like those from paper or flammable liquids. This combination enhances the alarm’s overall responsiveness, providing a faster response time in various fire situations.

In terms of design, the Kidde 820-1356 features a user-friendly interface. It includes a large test/silence button, which allows users to test the alarm’s functionality easily or silence it when necessary. The alarm also has a green power indicator light that lets you know it is functioning correctly, providing peace of mind at a glance.

Another important characteristic of this smoke alarm is its dependable power source. The Kidde 820-1356 operates on a sealed lithium battery that lasts for up to 10 years, eliminating the need for frequent battery replacements. This feature is particularly advantageous as it minimizes maintenance and ensures the alarm remains functional for an extended period. Additionally, the alarm emits a chirping sound when its battery is low to alert users to replace the unit.

The Kidde 820-1356 is also designed to be easy to install. With a quick-mount bracket and included hardware, users can install it in various locations around a home, including hallways, bedrooms, and living areas. This versatility ensures that critical areas are monitored effectively.
