Intended use
-
Opening monitoring of windows and doors
-
Operation in combination with suitable switching and dimming actuators
-
Battery-powered device
-
Installation on window or door
Use as opening monitoring according to firing ordinance (German Firing Regulations § 4)
Opening monitoring of windows in conjunction with room air extraction devices such as
extractor hoods and room air-dependent heaters.
If the windows are closed and the extractor hood is switched on, then underpressure may cause
smoke gas to enter living space.
The extractor hood may only be operated when a window is opened.
When the windows are closed, the power supply of the extractor hood must be interrupted.
i
No other transmitter type may be taught to radio actuators, used to interrupt the power
supply.
Functional description
The transmitter (1) detects the opening or closing of a window. As soon as a window is opened,
it transmits cyclical radio telegrams, which are evaluated by switching and dimming actuators.
The actuators only switch on when they receive radio telegrams. If the window is shut, no more
radio telegrams are transmitted and the actuators switch off their load after one minute at the
latest.
