Automatic control switch TX_44


Automatic control switches,
TX_44, colour aluminium
A water- and theft-resistant variation from the switch range Gira TX_44 is also available for outdoors at the basement stairs or garage. The automatic control switch reacts to heat and is simply used instead of the previous switch. That's convenient, safe and saves energy, because the light is only switched on when somebody enters the detection radius of the switch.

Standard top unit of System 2000

The Standard automatic control switch top unit can be used with diverse flush-mounted inserts of the System 2000, e.g. with a relay insert to switch light bulbs, fluorescent lamps and halogen lamps or with a Triac switch insert for switching HV and LV halogen lamps in the case of wound transformers. The automatic control switch top unit can also be linked to other automatic control switch top units by means of an auxiliary insert.

The brightness switching threshold can be adjusted from approx. 0 to 80 lux and brightness-independent switching for daytime operation can be set by means of a potentiometer at the device. The power-on time of approx. 2 minutes is fixed. In addition, the sensitivity can also be set and changed separately. This way, the top unit can be set optimally set for influences by lighting systems of neighbouring areas and other interfering influences and is suitable without restrictions for automatic light control in large auxiliary unit systems.

The Standard automatic control switch top unit is available for the installation heights of 1.1 m and 2.2 m.

Top unit Comfort of System 2000

The Comfort automatic control switch top unit can be used with System 2000 dimming inserts in addition to the System 2000 inserts for switching various lamp types and the HLK relay insert for lighting and heating or ventilation applications. A dimming function in the Comfort automatic control switch top unit ensures that the light is dimmed for a period of 30 seconds before being switched off ‑ a warning which is particularly important in a staircase. In addition, a dimming value can be stored via an auxiliary unit with which the automatic control switch switches on the lighting.

The Comfort automatic control switch top unit disposes of a digital signal evaluation in order to improve the detection behaviour and optimise the interference signal suppression. And a teach-in function allows simple storing of the current illuminance as the threshold value. The brightness switching threshold ( 0 - 80 lux), the sensitivity (100% - 20%), the delay time (10 s - 30 min.) and a brightness-independent switching for daytime operation can be set by means of potentiometers at the device.

The Comfort automatic control switch top unit is available for the installation heights of 1.1 m and 2.2 m.

Impulse insert

The System 2000 automatic control- switch top units can be used for motion dependent light control, e.g. in stairwells, can also be operated with the System 2000 impulse insert. The impulse insert sends a pulse to the time clock in the distributor when actuated, which then switches on the light for a specified time. With the potentiometers for the switch-on brightness in the automatic control- switch top unit, the response for each device in the lighting system can be set separately to the ambient conditions. The power-on time is set centrally at the automatic mechanism in the distributor cabinet.

Here up to eight impulse inserts can be connected to one automatic DRA mechanism. If only six automatic control switches with impulse inserts are used, any number of non-illuminated installation buttons may be connected for semi-automatic lighting control.
