Claims (2)
- ガス漏れ警報器が接続され、前記ガス漏れ警報器に対して未接続を検知する信号を出力するメータ通信手段を備えたガスメータにおいて、
前記メータ通信手段が、前記未接続を検知する信号を出力した後に、前記ガス漏れ警報器からの応答信号が入力されたか否かを判断し、前記応答信号が入力されたと判断した場合は、前記応答信号が認識できたことを示す返信電文を前記ガス漏れ警報器に出力し、以後電文方式にて前記ガス漏れ警報器と以降の通信を行い、前記応答信号が入力されないと判断した場合は、パルス方式またはON/OFF方式にて前記ガス漏れ警報器と以降の通信を行うことを特徴とするガスメータ。 - ガスメータと接続され、前記ガスメータからの未接続を検知する信号を検出して応答信号を前記ガスメータに出力する警報器通信手段を備えたガス漏れ警報器において、
前記警報器通信手段が、前記応答信号に対する返信電文が前記ガスメータから入力されたか否かを判断し、前記返信電文が前記ガスメータから入力されたと判断した場合は、電文方式にて前記ガスメータと通信を行い、前記返信電文が前記ガスメータから入力されないと判断した場合は、パルス方式またはON/OFF方式にて前記ガスメータと通信を行うことを特徴とするガス漏れ警報器。
