Alarm System — Concord 4
A hardwired Interlogix (GE / UTC Fire & Security) Concord 4 security panel, installed during the 2017 build by Global Security. It does not appear anywhere else in this manual — it was found in the owner’s own construction photographs, not confirmed at a walkthrough. Its single biggest open question also matters for the sale: whether this system was ever actually monitored.
At a glance
A hardwired Interlogix (GE / UTC Fire & Security) Concord 4 alarm control panel — an 8-zone board with a keypad bus and a phone-line dialer connection — installed as part of the original 2017 build. This page exists because the system turned up, fully documented down to the wiring diagram, in the owner’s 2017 construction photo archive. No one has opened the panel or confirmed its operation since.
- Where
- A locked steel enclosure (“the can”), mounted high on an interior wall inside a soffited alcove or closet, conduit-fed. Exact room to confirm at walkthrough — see Specs, owner’s edition. No keypad has been located in any photo yet.
- Must know
- The single most important fact about this system is what is not known. On install day, 2017-05-16, the panel’s cellular/IP communicator (an Alarm.com module) was still factory-sealed in its bag, unwired, sitting loose in the bottom of the can. Whether that module was ever installed afterward — and therefore whether this alarm has ever been actively monitored, whether it is monitored today, and whether any monitoring contract exists to convey or cancel — is genuinely unknown. Treat this system as unverified until it is professionally assessed; do not rely on it for security until then. Separately, its backup battery is nine years past its 2017 installation date and is certainly dead — a cheap, easy fix regardless of the monitoring question (see Maintenance).
- Status
- Existence, model, and wiring confirmed from 2017 construction photographs. Current operating status, monitoring status, keypad count/location, and panel room are all unconfirmed — assessment by a licensed alarm technician is the next step, not a walkthrough photo.
2Everyday use
Status unknown — do not rely on this system until it has been assessed. Everything below describes how a Concord 4 normally works; it is not a confirmation that this particular installation is currently armed, monitored, or even fully functional.
A Concord 4 is a conventional hardwired panel: a keypad takes a numeric code to arm or disarm the system, each door/window/motion sensor is wired to one of the panel’s zones, and an alarm event is supposed to be reported off-site by a communicator. Day-to-day, that’s the whole interaction model — nothing about it requires an app or a subscription to arm and disarm locally.
Why this page can’t tell you whether the house is actually protected
- No keypad has been identified in any photo — how many exist, and in which rooms, is unknown.
- The panel’s programming (which zone is which, whether it’s even armed away from home) has never been read out.
- There is no record of the label’s own required 3-year technician check ever happening (see Maintenance).
What this page is, and isn’t
3App & account
The Concord 4 board itself has no app or cloud account of its own — it is a 2000s-era hardwired panel that predates that model entirely. Any app-based control or monitoring on this system, if it exists, would come from the Alarm.com module found sealed and unconnected in the 2017 photo.
- If that module was later installed and activated, the relevant app is Alarm.com (or a monitoring company’s own branded app built on the Alarm.com platform) — but whether any such account exists for this house is unconfirmed.
- If the module was never installed, there is no app, and the only interface to this system is a physical keypad — location(s) still unknown.
- Before relying on this system after closing: find out from the seller whether an Alarm.com account, a monitoring contract, or a landline-based dialer connection is currently active, and if so, get the account transferred or canceled the same way the Schlage/Eufy/Rachio accounts are handled — see Smart-home account transfer.

4Maintenance
The backup battery is certainly dead — replace it regardless of anything else on this page
- The panel self-tests the battery automatically (every 24 hours, or every 4 hours if UL 98 options are set on) — a low-battery trouble condition should already be signaling on any connected keypad if one can be found.
- The panel’s own door label states it is UL/SIA CP-01 listed and carries a printed note that the system “is intended to be checked by a qualified technician at least every three years.” There is no record of that check ever having happened, on a system that is now roughly nine years old.
- Zone wiring uses 2kΩ end-of-line resistors at the last device on each loop (both the numbered zones and the Zone 8 smoke branch) — the number a technician will want if a zone needs troubleshooting or a sensor needs replacing.
- If a landline is what feeds this panel’s telco connection, confirm the line is still active before assuming the dialer path works — a disconnected landline silently defeats a phone-based alarm panel with no visible symptom.
Because Interlogix shut down as a company in 2020, there is no manufacturer support line to call. Parts (batteries, EOL resistors, compatible keypads) remain available through alarm-supply distributors, and any licensed alarm technician familiar with older hardwired panels can service this board — it does not require an Interlogix-specific specialist.
5Troubleshooting
| Symptom | First checks | When to escalate |
|---|---|---|
| You don’t know if the house is alarmed at all | Locate a keypad (location unknown — check likely closets/hallways first) and see if its display is lit. A dark, unresponsive keypad with the panel’s battery this old is consistent with a simply-dead backup battery rather than a dead system. | No keypad found, or a keypad found but its code is unknown — call a licensed alarm technician. Do not attempt to force the can open or guess codes. |
| Panel or keypad is beeping / showing a trouble tone | Classic causes on this platform: low/dead backup battery (near-certain here — see Maintenance), an open zone, or a telco fault. A dead battery is the first thing to rule out given its age. | Trouble tone persists after a battery swap — a technician should read the fault code off the keypad. |
| You want to confirm whether monitoring is active | Ask the seller directly whether an Alarm.com account or a monitoring contract exists, and check whether the house has an active analog landline (the panel’s only confirmed-as-installed communication path in 2017 was telco/RJ31X). | No landline and no confirmed Alarm.com activation — assume the system is local-alarm-only at best (a siren, no off-site notification) until a technician proves otherwise. |
| You need to change the code or reprogram anything | This panel’s programming has never been read out by this manual. Do not guess at an installer code. | Any programming change — call a licensed alarm technician, or Global Security if they are still operating (see Specs) as the company that has the most plausible existing record of this installation. |
A working panel is not proof of monitoring, and a dead panel is not proof there’s no protection at all

7Documents & links
Interlogix shut down as a company in 2020, so there is no live manufacturer site to link to — every source below is a distributor, dealer, or archive mirror hosting the manufacturer’s original PDF. Both links were checked and confirmed live at the time this page was written.
- Concord 4 — Installation Manual (PDF)
P/N 466-2182, Rev. K (Aug 2016) — hosted by an alarm dealer; the manufacturer’s own domain is dead. This is the document referenced on the panel’s own wiring-diagram sheet as “installation instructions 466-2182.” - Concord 4 — User Manual (PDF)
P/N 466-2183, Rev. E (Jul 2016) — also hosted by an alarm dealer. Provenance note: the panel’s own printed compliance block (photographed on the wiring diagram) reads “Manual Part # 422-2183,” but every independently-hosted copy of the actual “Concord 4 User Manual” found online — across at least five unrelated dealer sites — is numbered 466-2183. 466-2183 is treated here as the correct number; 422-2183 is most likely a transcription artifact of a blurry photo (4/6 and 6/2 are easy to conflate at a crop), not a genuinely separate document. - Interlogix Concord 4 — Install Guide (Alarm Grid)
A well-known, still-operating alarm equipment retailer’s own hosted copy of the same 466-2182 installation manual — cited as a second, independently-run mirror in case either PDF link above goes stale.

Section 8Technical reference ExpandCollapse
The engineering layer — for a buyer's technician, or a curious owner.
For the buyer (or technician) who wants the wiring-level picture — this whole page is sourced from one exceptionally complete photograph: the wiring diagram taped inside the panel’s own door, shot in May 2017 before the can was ever closed for good.
The source document is a factory wiring-diagram sheet (“422-3781 Rev. E”) taped inside the Concord 4’s enclosure door, photographed during the 2017 construction walk-through and never revisited since. It transcribes cleanly: full terminal legend, every accessory’s part number, the complete UL/SIA CP-01 compliance block, and a warning label about the panel’s alarm-verification delay feature. Nothing about this page’s hardware facts is a guess — they are read directly off that sheet. What the sheet cannot tell you is anything about the nine years since: whether the described hardware still exists in this configuration, whether it was ever reprogrammed, or whether the communicator question below was ever resolved.
Owner's edition
Full details in the owner's edition — serial numbers, configuration and identity details continue in the complete manual, handed to the buyer at closing.
Why the Alarm.com question matters more than anything else on this page: a Concord 4’s built-in communication path is a phone-line dialer through the RJ31X jack — nothing more, unless a separate module is added. The photographed Alarm.com module is exactly that add-on: a cellular/IP bridge that lets the panel report alarms without a working landline, and lets a monitoring company (or the homeowner, via the Alarm.com app) see status remotely. Finding it still factory-bagged, pigtail zip-tied, unconnected, at the bottom of the can on install day means that at that exact moment, this panel’s only path to the outside world was a phone line. Nothing in the record since 2017 confirms the module was ever installed, activated, or paired to a monitoring account — and nothing confirms it wasn’t. That is a real, unresolved gap, not a rhetorical one.
What normal operation would look like, if it turns out to be live: a SuperBus 2000 keypad (one of the models listed in Specs) takes a numeric code to arm/disarm; the board reports over the RJ31X telco connection and/or, if installed, the Alarm.com module; the exterior siren (an 8-ohm, 15-watt Piezo Dynamic unit per the diagram) sounds locally on an alarm event; and the panel self-tests its own battery automatically. None of that requires an app for basic function — the Alarm.com layer, if present, is additive (remote arm/disarm, push notifications, monitoring-company dispatch), not required for the panel to work as a local, siren-only system.
What to gather to close this page out: open the can and read the board’s serial number and current firmware/programming; confirm the room the can is actually in; find every keypad in the house and record its location and code; determine whether the Alarm.com module is now physically installed; confirm whether an active landline or an active Alarm.com/monitoring account exists, and under whose name; and, if Global Security is still operating (their listed number/site should be the first call), ask whether they hold any service or monitoring record for this address.
