Alarms, buzzers, and sirens are safety devices used in both industrial and commercial settings. The SC628ANP is such a device. It is an IECEx Certified audible alarm, making it suitable for hazardous environments and potentially explosive atmospheres.

The SC628ANP is IP66 ingress protected, making it highly environmental resistant, and it has the option of a built-in self-test feature. This feature runs a self-diagnostic test when the device is activated, allowing users to quickly and easily ensure their alarm is operating correctly.

The primary applications for the SC628ANP include fire alarm systems, signals warning of hazardous conditions and emergency announced systems, as well as any other application requiring an audible alarm. The SC628ANP uses a contemporary design, which allows it to be used in all types of buildings. Its waveguide design improves both sound quality and loudness.

The SC628ANP has a minimum sound pressure rating (SPL) of 119 dB at one metre, and is rated to the IP66 standard for dust and moisture protection. It is powered by 24VDC, and the sound can be triggered either internally or externally. It is also outfitted with an automatic dampening feature, reducing the SPL below a certain threshold. This will reduce the sound of an alarm when it has been sounding for a long time.

The working principle of the SC628ANP is quite simple. It has an interior siren, which is activated and powered by a 24VDC source. A trigger can be used to switch on the siren, either an internal or external trigger. The trigger is connected to a switch, which will then activate the siren. The siren is connected to the power source, and it will then produce sound through the waveguide.

The SC628ANP also has an automatic dampening feature, which can be set to either manually or automatically reduce the SPL below a certain threshold. This feature allows the user to control the sound amplification when needed. This is accomplished by connecting a dampening switch to the activation terminal.

Overall, the SC628ANP is an ideal audible alarm product for hazardous areas. It is designed to meet the standards for dust and water protection, and has the additional feature of self-testing. Its simple working principle and integrated dampening feature makes it a great choice for any alarm application.
