LED/buzzer combination 450 with acknowledgement function for AS-Interface®
Unique acknowledgement function with feedback signal via AS-Interface Bus
With the addition of the LED/buzzer Combination 450 with acknowledgement function, WERMA has expanded its range of products with integrated AS-Interface®. The combination unites a very bright light signal with the powerful sound of a buzzer. This product also features a unique acknowledgement function: by gently pressing the front surface of the product the audible signal can be turned off in a matter of seconds. This acknowledgement signal is fed back to the master via the AS-Interface Bus and the malfunction is only indicated by means of the optical signal.
Expanded addressing and a sound output of 80 dB
The Combination 450 for AS-Interface enables an expanded addressing (A/B technology) of up to 62 modules. The power required is drawn from the Bus voltage.
The LEDs radiate light both frontally and to the side, thus ensuring optimal all-round signal visibility. The 3 KHz continuous tone at a sound output level of 80 dB can be clearly heard above environmental noise.
Long life and maintenance free
Despite the range of features the LED/Buzzer Combination is highly economical and requires just 40 to 80 mA. As a result of the durable and maintenance free LEDs the combination has a life duration of up to 50,000 hours and can be simply attached to the yellow Bus cable by means of a 2-pole screwable connection.
The fact that the device does not need a sound outlet, enables it to conform to the high protection rating IP 65. The combination is therefore resistant to dust and splashed water. It is especially suitable for the control panel and switch gear programme due to its compact size.
The tone of the LED/Buzzer Combination 450 with acknowledgement function for AS-Interface can be tested at www.werma.com. Here you will also find further products with integrated AS-Interface.
