The license statement#

Telelink Business Services is a licensed C-7 Low Voltage Systems Contractor, CSLB License #472017. The company has been in business in Sacramento since 1983. That number appears in our footer, on our proposals and in the prequalification packet, and it is the one to check. The about page covers the history and what we install.

What the C-7 classification covers#

The C-7 Low Voltage Systems classification, defined in Title 16 of the California Code of Regulations, covers communication and low voltage systems that are energy limited and do not exceed 91 volts: telephone, sound, CATV, CCTV, satellite, instrumentation and temperature controls, and low voltage landscape lighting. In practice that covers everything on the services page: structured copper and fiber cabling, network rooms, wireless, IP cameras, access control, intercom and entry, CATV distribution, phone systems, audio visual and nurse call. Fire alarm is the classification’s one express exclusion.

ScopeWho carries it
Structured cabling, fiber, wireless, network roomsTelelink, self-performed
Video surveillance, access control, intercom, entry systemsTelelink, self-performed
CATV and MDU distribution, phone systems, AV, nurse callTelelink, self-performed
Fire alarmThe project’s fire alarm contractor. The one express exclusion in the C-7 classification
Burglar or intrusion alarm, alarm monitoringA licensed alarm company, under a BSIS Alarm Company Operator license
Electrified door hardware (strikes, maglocks, panic devices, operators)Division 08, or a licensed C-28 contractor
Line voltage, dedicated circuits, telecom room bondingThe electrician, C-10. Handoff shown on drawings

Those scopes run in commercial and institutional buildings, multifamily included. Cameras and access control are installed under the C-7 classification. Alarm monitoring runs under a separate BSIS Alarm Company Operator license, so a monitored account goes to a licensed alarm company while the low voltage infrastructure under it stays with us.

How to verify the license at cslb.ca.gov#

Go to cslb.ca.gov and open Check a License from the main menu. You can search by license number, business name or personnel name; the license number, 472017, is the fastest. On the results page, select the license number to open the detail record. It shows the business name, the issue and expiration dates, the current status, the classifications held, the contractor bond with surety and amount, the workers compensation carrier and policy dates, the personnel on the license, and any disciplinary history. Save it for the prequalification file. If anything on that record does not match this site, call us at (916) 340-7503 before award.

Bond and insurance on public record#

The CSLB record shows the $25,000 contractor license bond that California has required of every active licensee since January 1, 2023. General liability coverage is $2,000,000, and workers compensation is active. Certificates of insurance with additional insured endorsements naming the GC and owner, and waiver of subrogation where the subcontract requires it, are issued per project and included in the prequalification packet described on the for general contractors page.

Certifications and how they are documented#

This page lists only what can be verified. DIR public works registration, any BICSI credentials held by individual technicians, and any manufacturer training records are furnished in the prequalification packet as copies of the documents rather than as claims on a web page. Manufacturers whose equipment we install and configure, such as Cisco Meraki, Yealink, ButterflyMX and DoorKing, are named on the service pages in plain words without a dealer or partner claim.

Why the license number is on every page#

California Business and Professions Code section 7030.5 requires a licensed contractor to include the license number in all advertising, and CSLB treats a website as advertising. That is why CSLB #472017 appears in the footer of every page on this site and in the license statement above.

What to ask any low voltage bidder#

Before you place a low voltage contractor on a bid list, ask for the license number and check that the classification is C-7 or another classification that actually covers the scope, and that the status is active. Confirm the business name on the bid matches the license record. Ask whether they self-perform or broker the labor. Ask for the workers compensation certificate, not a verbal assurance. On public work, ask for the DIR registration number and check it on the DIR website. If the scope includes cameras on a federally funded property, ask how they document NDAA compliance. If they list fire alarm or alarm monitoring as a service under a C-7 license alone, ask what other license covers it. Each of those questions can be answered with a document, and you can ask any bidder to produce it. The C-7 license explainer goes deeper for anyone who wants it.

Next step#

Verify license 472017 at cslb.ca.gov, then send the drawings and the Division 27 and 28 sections through the request a bid page or to carson@telelinkca.com. The bid comes back with the license number, the classification, the insurance summary and the scope handoffs on the first page, so your compliance desk can clear it without a follow-up email.

General contractors who need the full prequalification packet can ask for it by email. A complete packet contains the CSLB printout, the bond and insurance certificates, the workers compensation certificate, the carrier’s experience modification rate letter, DIR public works registration and the written safety program, and ours is assembled to that list. The for general contractors page sets out the contents in full.
