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 and the red LED blinks every 10 seconds.
Silence Button: Many smoke detectors have a ``silence'' or ``hush'' button. Press this button to temporarily silence the alarm. This is often effective for a short period, but the beeping may resume after some time if the battery issue persists.
Next, on the back side of the alarm, locate the area marked with a long arrow on the product label. Break through the label with a screw driver and turn the screw to the “OFF” position. This will deactivate the alarm, stop the end-of-life warning and render the alarm safe for disposal by draining the battery.
Clean The Alarm
Dust and debris can affect the alarm. As far as it is concerned, the spider web or speck of dust that is obscuring the sensor is a potential fire and therefore the alarm needs to be sounded. The easiest way to clean an alarm is to run a vacuum cleaner over the vent.
Break through label with a screwdriver. Turn the screw to the “OFF” location. This will deactivate the alarm, stop the low battery chirp and render the alarm safe for disposal by draining the battery. NOTE: Turning off the alarm is permanent.
To get your smoke alarm to stop chirping if you've already changed the battery, first try draining any residual charge by holding the test button down for 15 seconds. If this doesn't solve the problem, clean the unit. A blast of compressed air will often remove the dust particles that are causing the beeps.
Stopping a smoke alarm from beeping is often simple. Get a step ladder and carefully reach for the alarm. Pressing the “Test/Silence” button on the front of the unit should stop it from beeping or chirping. If this doesn't work, grasp the device and turn it counterclockwise.
All smoke detectors should be replaced at least every 10 years and tested regularly to ensure the alarm is functioning properly. At the end of ten years, the smoke detectors will give an end-of-life warning letting you know to replace the alarm.
Some smoke alarms have a processor that retains certain error conditions, such as a weak battery. The error condition should reset when the battery is replaced, but sometimes it doesn't and must be manually reset to clear the error.
Humidity, dust particles or small insects in the smoke chamber can cause false alarms; this can be solved by vacuuming the mesh and drying the smoke alarm. You may need to relocate your smoke alarm if it is too close to the kitchen, bathroom, air condition units or any other source of humidity.
Previously, the replacement of smoke alarms older than 10 years was merely a recommendation. However, with the updated legislation, it has become a mandatory requirement. The rationale behind this change is rooted in the reliability and effectiveness of smoke alarms.
Use thumb to pull deactivation tab outward until tab snaps into place. This will discharge the powercell and deactivate the unit.
In most cases, you can find the 'hush' button on the smoke detector's cover.
Your smoke detectors don't have an inside voice — for your safety. If you hear your smoke detector beeping in brief chirps every 30-60 seconds, it's probably time to replace the battery. Or you might need to clean out the dust, check the battery connections or replace the whole smoke alarm.
For hardwired or wireless alarms, only hushing the initiating unit will silence all other interconnected alarms (see below on how to find the initiating unit). 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 Kidde Smoke Detector is powered by a 10-year lithium battery that requires no wiring, never needs replacing, plus coverage during a power failure. A solid green LED indicates that the alarm is receiving power and a red LED indicates that the smoke detector is sensing smoke or fire.
Press the hush/silencing button. It will silence the entire interconnected system. The button may also say “test.” It should silence all the alarms immediately unless there's still smoke and debris. It will reset in eight minutes, given that the smoke and debris have dissipated.
The battery may need to be replaced. An alarm will chirp every 30 to 60 seconds for a minimum of seven days. With a "low battery" announcement, disconnect the unit and replace the batteries. You can also put a unit into low battery hush for up to 12 hours on newer units by pressing the test/hush button.
The chirp will not stop until the unit is powered off. You'll know that it is an end-of-life warning and not a low battery warning because replacing the batteries will not stop the chirp. The chirp will stop only when the alarm is powered off.
