RL78/G10
Window Alarm with Buzzer

This solution could be installed on windows and doors for entry etc. When vibration caused by an outside force is detected, an alarm will sound to scare off intruders.

<Operation>
• The device enters STOP mode until vibration is detected.
• When vibration is detected, the device is released from STOP mode and sounds an alarm.

Household Gas Alarm

This system is for warning people with a flashing LED and buzzing alarm as soon as a change in the carbon monoxide concentration is detected due to gas leakage, incomplete combustion, etc. This simple device could improve the level of safety in a home.
So that the operating time can be shortened, the waiting time on this tool is variable.

<Operation>
• When this system is activated, the LED is turned on, the buzzer sounds, and the system enters the normal mode.
• The LED is turned on every 3.75 seconds (every 20 seconds in normal state).
• When the following conditions are satisfied, the buzzer issues an alarm.
The carbon monoxide concentration is 50 ppm or more for 15 seconds (60 minutes in the normal state).
The carbon monoxide concentration is 100 ppm or more for 7.5 seconds (10 minutes in the normal state).
The carbon monoxide concentration is 300 ppm or more for 3.75 seconds (3 minutes in the normal state).
• When the carbon monoxide concentration is less than 50 ppm for 60 seconds, the system returns to the normal mode.

Automatic Air Volume

Temperature data is acquired from the temperature sensor every 3 minutes, and the fan is controlled according to the temperature.
So that the operating time can be shortened, the check interval of temperature is changed to several seconds on this tool.

<Operation>
• The fan is controlled according to the temperature.
Lower than 20°C : Stopped
20°C to 28°C : Low-speed rotation
28°C to 35°C : Medium-speed rotation
35°C or higher : High-speed rotation
