Wireless Battery Operated Smoke Alarm Detector for Home Fire safety KD-129D

KD-122LA Wireless Interconnected Fire Detecting Alarm is a photoelectric smoke alarm with low power consumption. Internal precise analog circuit, digital circuit and wireless transmission circuit make the detection work more stable and reliable. It has wireless interconnection function, which means when one unit makes alarm, other interconnected units within the interlink range will alarm at the same time. This product has small volume and the built-in large-capacity battery can provide service life of 10 years.

The household gas alarm is developed by adopting advanced electronic techniques and gas detecting techniques. It is of high sensibility and is applicable to detecting the leakage of household gas, liquid gas and natural gas. The sensor reacts with the diffused gases in the air directly and generates linear voltage signal .When the detected gas density reaches a setting value, the alarm will send out acousto-optic alarm signal to remind users to take measures in time. The product gas alarm has a special design,modern and fashion, and is of the convenience to use.

This product has the following features:

• This alarm has been designed and tested to detect CO in a residential environment. 
• It implements standard BS EN 50291-1:2018. 
• It uses electrochemical sensor and has high sensitivity, stable performance, strong anti-interference, small size and long service life. 
• It can provide sensor fault warning, low battery warning, end-of-life warning and low CO concentration warning.

KD-122LH Fire Detecting Smoke Alarm is a photoelectric smoke alarm with low power consumption. It can be connected to a mobile phone APP via wireless WiFi. Internal precise analog circuit and digital circuit make the detection work more stable and reliable. 3 AA batteries allow the product to standby for more than 3 years. The product has a service life of up to 10 years.
