Product Data Sheet 521B 6/24 Vdc 2-wire smoke sensor with CleanMe signal The 521/541 series self-diagnostic, two/four-wire smoke detectors are the industry's first conventional direct-wire smoke detectors with analog features such as drift compensation and multi-criteria detection. The 521/541 series continually monitor their own sensitivity and operational status, and provide a visual indication if they drift out of the sensitivity range or fail internal diagnostics. This meets NFPA 72 field sensitivity testing requirements without the need for external meters. Applying a magnet near the detector’s integral reed switch activates additional diagnostic information. This initiates a self-diagnostic routine and provides visual indication of sensitivity level Standard Features or indicates if service is required.

Frequently asked questions

At GID Industrial (Elite.Parts' parent company), we specialize in procuring industrial parts. We know where to find the rare and obsolete equipment that our customers need in order to get back to business. There are other companies who claim to do what we do, but we're confident that our commitment to quality and value is unparalleled in our field.

Warranties differ by part and by which suppliers we use to procure it for you. Sometimes, a part will be sold as-is and without a warranty. Our specialty, single board computers, tend to receive a one-year warranty.

Elite.Parts can ship via FedEx, UPS, DHL, and USPS. We have accounts with each of them and generally ship using one of those, but we can also ship using your account if you would prefer. However, we can use other carriers if it will be more convenient for you.

Absolutely! We are happy to serve customers regardless of location. We work with international clients all the time, and we are familiar with shipping to destinations all across the globe.

All major credit cards are accepted: Visa, MasterCard, Discover, and American Express. We will also accept payment made with wire transfer or PayPal. Checks will only be accepted from customers in the USA. Terms may available for larger orders, upon approval.

GO TO SOURCE

When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
