Hardwired smoke alarms triggering randomly are often caused by a low backup battery, dust/cobwebs, high humidity, or an expired unit (10-year lifespan). First, ensure there is no fire. Then, silence it by holding the test button, cleaning it with compressed air/vacuum, replacing the battery, or replacing the unit.
Methods for Resolving False Alarms in Hardwired Smoke Detectors:
Check the Backup Battery: Although the device is hardwired for power, it typically contains a built-in 9-volt backup battery; if the battery power is low, the device will emit a chirping sound or an alert signal.
Clean the Sensor: Dust, cobwebs, or small insects may enter the sensing chamber, thereby triggering a false alarm. Please use a vacuum cleaner attachment or a can of compressed air to clean the device.
Reset the Device: First, shut off the power at the circuit breaker; then, remove the alarm unit, unplug the power connector, take out the battery, and press and hold the test button for 15 to 30 seconds to completely discharge any residual power remaining within the device.
Check the Service Life/Expiration Date: Smoke alarms typically become ineffective after 10 years of service. Please check the manufacturing date located on the back of the device; if the unit has been in use for more than 10 years, it must be replaced.
Rule Out Environmental Factors: High humidity, steam generated in bathrooms, or cooking fumes can all trigger the alarm. Please ensure that the smoke alarm is installed at a sufficient distance from these areas.
We recommend a hardwired photoelectric smoke detector and alarm
The ANKA AJ-710 series consists of hardwired AC-powered photoelectric smoke alarms designed specifically to meet Australian safety standards. Primarily powered by a 240V domestic mains supply, these units are also equipped with a backup battery to ensure continued operation in the event of a power outage.
Core Features and Models
This series comprises several sub-models, distinguished primarily by the type of backup battery utilized:
AJ-710M-9: Equipped with a replaceable 9V DC backup battery.
AJ-710M-3: Equipped with a 3V lithium battery (typically a non-replaceable, 10-year lifespan type) for backup power.
Key Technical Specifications
Power Source: 240V AC mains supply, 50Hz frequency.
Detection Technology: Employs photoelectric sensing technology, which is particularly sensitive to smoldering fires (smoldering smoke).
Interconnection Capability: Supports hardwired interconnection; an optional wireless RF module is also available to enable wireless interconnection. When one alarm detects a fire, all alarms within the same circuit will sound simultaneously.
Silence & Test: Features a large central button that allows users to easily perform periodic functional tests or temporarily silence the alarm (Hush mode) in the event of a false alarm.
Certification Standards: Complies with the Australian standard AS3786:2014 and holds ActivFire certification (AFP-3943).
