Linear Keypad & Intercom Repair Nationwide

Linear Keypad & Intercom Repair: The Roswell Owner’s Guide

Linear keypad and intercom repair in Roswell typically runs $195-$475 installed, depending on whether we’re replacing a standalone keypad, a telephone entry unit, or the wiring run between them. We stock the common Linear AC-1, AE-1, and ACP series parts on our vans, and most residential repairs in Roswell are completed same-day. Homeowners usually discover the failure when the gate stops responding to keypad codes, the intercom produces static or silence, or visitors can hear but not release the gate remotely.

Which Linear Models This Applies To

Linear manufactures several overlapping product lines, and the part you need depends on when your system was installed. The AC-1 series (single-family residential keypads) and AE-1 series (telephone entry systems) are the most common in Roswell’s older neighborhoods, particularly near the Canton Street corridor where estate-style swing gates from the early 2000s still carry their original equipment. The ACP series (access control processors) and newer LNW and R4 systems use different mounting footprints and voltage requirements.

We identify the correct part three ways: the model sticker inside the keypad housing (usually on the circuit board), the part number on the existing power supply, and the wire count running to the gate operator. OEM Linear parts carry a two-year manufacturer warranty; quality aftermarket equivalents from Seco-Larm and EMX match the spec at roughly 30% lower cost but carry one-year coverage. For intercom systems integrated with home telephone wiring, we generally recommend OEM to avoid frequency-matching issues with older Nortel or Avaya home systems still found in Roswell’s 1980s-1990s builds.

Signs Your Linear Keypad & Intercom Repair Is Failing

• Keypad accepts codes but gate does not move. This usually points to a failed relay on the keypad’s output board or a break in the low-voltage control wire between keypad and operator. In Roswell, we see this often after landscaping crews nick buried conduit near the gate post.
• Intercom audio is present but gate release button fails. The listen and talk circuits are separate from the door-release relay. The relay contacts pit over time, especially on systems that see heavy visitor traffic near Roswell’s commercial corridors.
• Keypad works intermittently, worse in morning or evening. Temperature-related failure of the backlit membrane or power supply voltage sag. Georgia’s humidity accelerates corrosion on the ribbon cable connectors inside AC-1 housings.
• Complete silence from intercom, no dial tone or call tone. Often the 16-volt transformer has failed, or the telephone line interface card has taken a surge. Lightning season in north Georgia keeps us busy with these from May through September.
• Keypad buttons require hard presses or multiple tries. The silicone membrane beneath the buttons degrades after roughly 8-12 years of UV exposure. On south-facing gates in Roswell, we’ve replaced membranes at six years.

Replacement Cost & What’s Included

Most Linear keypad repairs in Roswell fall between $195 and $475, complete. A standalone AC-1 keypad replacement with labor runs $195-$295. Telephone entry units (AE-100, AE-500 series) range $325-$475 including reprogramming of up to 25 resident codes. Wiring repairs between keypad and operator add $85-$150 depending on trench length and conduit condition.

The price we write down before starting is the price on the invoice. That figure includes the part, labor, programming, and testing. Under our 365-Day Done Right Promise, if the same symptom returns within a year, we make it right at no charge. Every repair leaves a documented photo record under Haven Standard Clause 4: what we found, what we replaced, and the final settings.

DIY or Call Us?

There’s a safe middle ground. You can verify power at the keypad transformer with a multimeter, check for obvious wire damage near the gate post, and confirm the gate operator itself responds to its internal test button. What you should not do: open a telephone entry unit connected to live phone lines, attempt to reprogram resident codes without the installer manual, or run new low-voltage wire through existing conduit without verifying it’s de-energized.

We’ve been called to Roswell jobs where a homeowner’s DIY keypad replacement worked for two weeks, then failed because the new unit drew 500mA and the original transformer was rated for 300mA. The mismatch wasn’t visible until the transformer overheated. If you’re matching parts yourself, check amperage draw and voltage drop over the wire run, not just model compatibility. Or call us at (706) 928-9815 and we’ll bring the right part already verified for your system.
