FAAC Keypad & Intercom Repair Nationwide

FAAC Keypad & Intercom Repair: The Johns Creek Owner’s Guide

FAAC keypad and intercom repair in Johns Creek typically runs $280-$520 installed, depending on whether the fix is a membrane replacement, full keypad swap, or intercom board rebuild. We stock FAAC-compatible components for the 400, 422, and S800 series on our trucks, and most residential keypad or intercom calls in Johns Creek are completed same day. Homeowners usually notice the failure first thing in the morning: the keypad beeps but doesn’t transmit, the intercom crackles then goes silent, or the gate stops responding to any code entry entirely.

Which FAAC Models This Applies To

FAAC has produced three distinct keypad and intercom architectures over the past fifteen years, and the parts are not interchangeable between them. The 400 series (402, 422, 424) uses a 12-volt hardwired keypad with a dedicated two-wire bus to the control board; the S800 residential line moved to a proprietary RF keypad paired at the receiver; the newer XK series and integrated intercom modules share a CAN-bus communication protocol that requires matching firmware revisions between keypad and board.

To identify yours, check the label inside the keypad housing or the FCC ID stamped on the back. The 400-series keypads are rectangular, roughly 4.5 by 3 inches, with a metal faceplate. S800 keypads are slimmer, plastic-bodied, and usually mounted on a gooseneck post. If your intercom is a standalone FAAC unit, the model prefix (XT, XS, or XK) tells us which protocol converter, if any, sits between the intercom and the gate operator.

We carry OEM FAAC membranes and housings, and we also stock quality aftermarket equivalents from EMX and Linear that match the 400-series voltage and pinout. For S800 and XK systems, we generally recommend OEM because the pairing procedure is brand-specific. We are an independent service provider, not affiliated with FAAC.

Signs Your FAAC Keypad & Intercom Repair Is Failing

• Keypad buttons require multiple presses or feel mushy. The silicone membrane beneath the buttons has degraded, usually from UV exposure and the thermal cycling common in Johns Creek. The membrane is a $40-$65 part; the labor is in disassembling the housing without cracking the sealed gasket.
• Intercom audio is present but the gate won’t release. The call button and speaker circuit are intact, but the dry-contact relay that signals the operator has burned or welded shut. This happens when the intercom’s internal relay is rated for 1 amp and the operator’s strike draws more on a hot Georgia afternoon.
• Keypad lights up, no beep, no gate movement. The 12-volt supply is reaching the keypad, but the data line to the control board is open. We’ve traced this to rodent damage in the conduit on several Johns Creek properties near the Chattahoochee, where chipmunks chew through low-voltage wiring in PVC runs.
• Code works intermittently, worse after rain. Water intrusion at the housing seam or the base of the gooseneck post. The 400-series metal housings corrode at the bottom edge; the S800 plastic housings crack at the mounting bolt holes. Either way, moisture reaches the board and causes erratic behavior until it dries.
• Intercom powers on, no dial tone or no connection to the house phone. The two-wire phone-line bridge has failed, or the VoIP adapter in the home has dropped the analog voltage the intercom expects. We see this increasingly as Johns Creek neighborhoods transition from copper POTS to fiber-based phone service.

Replacement Cost & What’s Included

The range depends on three things: whether we can reuse the existing housing and mounting post, whether the wiring run needs replacement (especially in the older neighborhoods off Medlock Bridge Road where direct-burial cable has shifted with freeze-thaw), and whether the control board requires a firmware update to recognize a newer keypad model. We hand you a written, itemized price before any work starts. That price does not change when the job is done. Under our 365-Day Done Right Promise, if the keypad or intercom fails for any reason related to our repair within one year, we return and make it right at no charge.

Every visit includes a documented photo record: the condition of the housing when we arrived, the part number of the component installed, and the keypad or intercom functioning before we leave. You get a copy; we file the rest under Haven Standard Clause 4.

DIY or Call Us?

There is one safe check a homeowner can make: verify that the keypad or intercom has power at the base. If it’s a hardwired unit, confirm the breaker feeding the operator hasn’t tripped. If it’s battery-backed, the keypad may show lights but lack the amperage to transmit; a voltmeter at the terminal block will read 12 volts or it won’t.

Beyond that, we don’t recommend owner repair. The 400-series keypads store programmed codes in volatile memory; disconnect power without backing up the code table and you’ll be reprogramming every remote and every user code from scratch. The intercom’s relay board carries line voltage on the strike circuit even when the keypad side is low-voltage. And the S800 pairing procedure requires a sequence on the receiver board that, done out of order, can de-pair every other device on the property.

We’ve been called to Johns Creek homes where the owner replaced the keypad successfully but spent three hours re-pairing remotes, or where a well-meaning attempt to clean a corroded housing with contact spray dissolved the membrane adhesive entirely. Name what you found. Name what it costs. Name what you left behind. Call (678) 394-1765 and we’ll quote the repair flat, in writing, before we pick up a tool.
