DIN EN 50291, Schabus 300266 GX-A1 + CO sensor TÜV pr.

Schabus 300266 GX-A1 + CO sensor TÜV pr.

As with the GX-A1, there is also the special version with the TÜV-tested COsensor for the new GX-A1 +. On the one hand, the CO-sensor needs a higher operating voltage for its own alarm, on the other hand, it is now possible to have a ppm-accurate display and an equally accurate alarm. The warning levels and delay times are the same as the parameters specified in the standard DIN EN 50291, which you will find on page 74 below right. The special advantage of the GX-A1 + CO is the possibility to monitor a room for harmful CO- concentrations, but to leave the actual warning device outside, in order to be informed already before entering the room, as long as this can be entered at a high level of the AC, for example. In the event of a danger, gas thermal systems should also be switched off to prevent further CO flow. A further relay for up to 60 volts of DC voltage will inform the house automation or The GAS ALARM GX-A1-CO is a combination of ext. COsensor and carbon monoxide control unit and warns at COconcentrations defined in DIN EN 50291 (CO in residential areas). This monitoring system is therefore very sensitive to its purpose. This CO- gas warning device may only be used together with the included CO- sensor. An LCD- display keeps you informed about the operating state. The alarm signal is acoustic and optical, both on the control unit and on the sensor itself. At the same time, a potential-free relay is switched to, for example, lock the gas supply with a magnet valve, so that no more gas can escape at a possible leak in the gas line or in the gas therme. A further relay switches in the event of technical disturbances detected by the control unit itself. The device shall not be used in potentially explosive spaces. Control unit and sensor are coordinated. Only operate the two devices together and only in dry indoor rooms with housing-like use, e.g. in residential rooms, shops, office rooms, in dusty workshops, seminar rooms, etc. Technical data: operating voltage: 100 - 240 V AC / 50-60 HzPower name: max. 10 VA, depending on the operating condition, typical 3 - 5 VA sensor operating voltage: 24 volt, max. 50 mA (green + / brown) sensor technology: electrochemical life sensor max.: 6 years @ max. 40 ° C + min. 40% rH10 years @ max. 28 ° C + min. 30% rHrelais contact alarm: 250 V ~ / 5 A (potential-free changer) relay contact failure: 60 V = / 5 A (potential-free changer) sound pressure control unit and sensor: 85 dB (A) (100 cm distance) software version: from X1.07C control unit range: -15 ° C... + 40 ° C / 10... 90% humidity, non-cond.functional sensor range: 0 ° C... 60 ° C / 10... 90% humidity, non-condensable protection: IP20 (device) device: 550x5 mm sensor: 5x5 mm (Pxx) for the control unit on request: 5x5 mm
