(2). Working current: ≤220mA;

(3). Alarm box light signal is clearly visible at 20m in the dark;

(4). Alarm box voice alarm sound level intensity ≥85dB (A).

KXB127(A) explosion-proof and intrinsically safe language sound and light alarms

1. Overview

KXB127(A) explosion-proof and intrinsically safe verbal acousto-optic alarm is equipped with multiple triggering and displaying alarm functions, which can be modified into various triggering modes such as point-touch and hold according to the needs of the site, and it can be used in the winch transportation lane, the cable car transportation lane, the belt transportation lane, the duct duct, the head of the tunnel, and the turning place of the locomotives of the flat lane.

It can be used as a safety warning signal. The product sends out the voice prompt signal at the same time, scrolling display of Chinese character subtitles as a warning signal to prompt pedestrians. It is characterized by small volume, light weight, novel design, advanced function, stable performance and multi-purpose.
