Searching for fire alarm phone line replacement, call box POTS replacement, or gate entry system copper line takeover? Here's what's changing, which systems are affected, and how Fireside Security converges all of it into one project.
If you manage or maintain a multifamily property and you're searching for fire alarm phone line replacement, call box phone line replacement, or gate entry system POTS replacement, you're not early — carriers are actively shutting down the copper lines these systems depend on right now. This page covers what's disappearing, exactly which equipment and manufacturers are affected, and how Fireside Security handles the takeover for both life-safety and access control systems in one coordinated visit. For the broader carrier timeline, see our POTS replacement overview and our companion piece on the multifamily POTS convergence.
Why "POTS replacement" is suddenly everywhere
POTS — plain old telephone service — is the analog copper line that has carried dial tone to buildings for generations. AT&T, Lumen, and regional carriers are retiring that copper network, market by market and wire center by wire center. There's no single nationwide shutoff date; instead, carriers are issuing shutdown notices, refusing new orders, and "grandfathering" existing lines ahead of full retirement. For property owners, the result is the same either way: any system still dialing out over copper is on borrowed time.
For multifamily housing specifically, that copper touches two categories everyone searches for separately but which usually need replacing together: fire alarm monitoring lines and gate entry / call box / access control lines.
Fire alarm phone line replacement
Most fire alarm control panels use a Digital Alarm Communicator Transmitter (DACT) to send fire, supervisory, and trouble signals to a central monitoring station over two analog phone lines, as required under NFPA 72. When the copper goes away, the panel loses its ability to report — which typically puts it into trouble condition and can trigger a failed fire inspection or a red tag from the local fire marshal / AHJ. Full monitoring scope lives on our fire alarm monitoring service page.
Fire alarm panels and communicators we regularly take over from POTS include:
- Honeywell Fire-Lite and Honeywell Silent Knight panels
- Notifier (Honeywell) fire alarm control panels
- Simplex (Johnson Controls) panels
- Edwards (Carrier) fire alarm systems
- Siemens fire alarm panels
- Gamewell-FCI control panels
- Bosch fire alarm systems
The DACT itself is typically replaced with a UL 864 / UL 365-listed cellular or IP communicator, such as those from:
- Honeywell AlarmNet
- DMP (Digital Monitoring Products)
- Telguard
- Alarm.com commercial communicators
- Uplink
Because this is life-safety equipment, the replacement isn't just a hardware swap — it requires proper communicator programming, signal verification, central station reprogramming, and documented testing that satisfies your AHJ.
Call box and emergency phone POTS replacement
Parking structures, courtyards, elevator cabs, and building entrances often rely on emergency call boxes and courtesy phones that dial out over the same disappearing copper. Common call box and emergency phone manufacturers include:
- Talk-A-Phone
- Code Blue Corporation
- Rath Communications
- Emergency Technology Inc. (ETI)
- Viking Electronics
- CyberData
Elevator emergency phones in particular are code-required to reach a monitored line at all times, so a copper outage on these lines is both a compliance and a life-safety issue, not just an inconvenience. Our elevator monitoring service handles cellular takeovers on that path directly.
Gate entry and access control system POTS replacement
Multifamily gate entry, intercom, and door access systems frequently use an analog line to dial a resident's phone for remote gate release, or to report tamper and forced-entry alarms to a monitoring center. Manufacturers and systems we commonly convert off POTS include:
- DoorKing telephone entry systems
- Linear (Nortek) access and entry systems
- Aiphone intercom and entry systems
- Mircom telephone entry systems
- BFT gate and access control systems
- LiftMaster commercial access systems
- Essex Electronics keypad and entry systems
Replacing these with IP or cellular-connected controllers isn't a one-for-one swap. Analog lines drew their own power and needed almost no configuration; cellular and IP-based replacements need power, a data connection, and correct setup — resident codes, visitor access, and monitoring center reporting all have to be reconfigured and tested before the gate works the way residents expect. See integrated access control and video surveillance for how we scope the full build.
Why one property needs both takeovers at once
Because fire alarm lines and access control lines are usually on the same carrier and often the same wire center, they tend to go dark on the same timeline. Coordinating both replacements as a single project — one site mobilization, one round of testing, one relationship with your monitoring center — is significantly more efficient than treating them as separate vendor engagements. That convergence is the core of how Fireside Security scopes these projects for multifamily portfolios.
What to do now
- Inventory every line — walk the property and identify every system still dialing out over copper: fire panels, gates, call boxes, elevator phones.
- Check your carrier notices — if AT&T, Lumen, or your regional provider has issued a copper retirement notice for your wire center, that's your real deadline.
- Scope it as one convergence project — fire alarm and access control together, not two separate truck rolls.
- Get ahead of your next fire inspection — a failed test because of a dead phone line is entirely avoidable with advance planning.
