Are noises from the "cat flap" recognised?

Even the noises from a cat flap can be filtered when the filtered out network is set. So when the cat "creeps in" it doesn't set the alarm off.

LISTENER Gas detector

Gasmelder Gas detector with internal sirens 85 dBA, certified according to BS 7348/1990, EN 60335-1. If you use natural gas or bottled gas (propane, butane and methane) this gas alert device can save your life. Because you are alerted of leaking gas immediately and reliably with a deafening audio signal. If this named gas leaks and mixes with oxygen, it creates a highly flammable gas mixture. Even the smallest spark can cause an explosion. The gas detector alerts you well before the explosive level is reached.

Connection via remote transmission.
