Why Monitoring Gets Written Out Before the Right People Read In
This article is for commercial electrical contractors, access control integrators, and facility managers who oversee fire-rated door openings with electric strikes. The specific problem it addresses is a recurring one: the latchbolt and locking cam monitoring option on a heavy-duty, fire-rated electric strike gets removed from the hardware schedule at some point between the architect's initial spec and the access control contractor's rough-in — and nobody flags it until an inspector or a security report surfaces an unmonitored fire door.
The opening discussion that leads to this outcome usually sounds reasonable at the time. The monitoring option adds cost. The access control scope is still being written. Someone decides the door position switch will handle status reporting. The result is an installed strike that does its primary job — controlling entry — but provides no feedback to the panel about whether the latch is actually engaged or whether the cam has returned to the locked position after the door closes.
What Latchbolt and Cam Monitoring Actually Does
On a fire-rated, fail-secure electric strike with a monitoring option, the device contains an auxiliary switch that reports two distinct conditions back to the access control panel:
- Latchbolt status: whether the latchbolt from the lock or exit device is physically captured in the keeper.
- Locking cam status: whether the internal cam has returned to its secured (locked) position after the solenoid de-energizes.
A door position switch, by contrast, only tells the panel that the door leaf is closed. It does not confirm that the latch is engaged or that the strike mechanism has reset. On a fire-rated opening, those are not the same thing. A door can be fully closed and still have a latchbolt that did not seat — perhaps because the door was pulled closed too slowly, because the lockset is misaligned, or because the strike keeper has shifted slightly over time.
In a healthcare corridor, a school stairwell, or an industrial building with fire-rated cross-corridor doors, an unlatched fire door that appears closed on a panel map is a life-safety exposure, not just a maintenance note.
Where in the Project Timeline the Monitoring Option Disappears
The spec usually starts with monitoring included. The architect or consultant writes a performance requirement for the opening that references auxiliary switch output, often because a life-safety consultant or the facility's own access control standards required it. The problem is that the monitoring suffix on the strike model — the designator that tells the factory to include the auxiliary switch assembly — lives inside the hardware schedule, not the access control drawings.
Here is how it gets lost:
- The hardware consultant issues a schedule with the correct model and monitoring suffix included.
- The general contractor receives a value-engineering request and the hardware supplier provides an alternate model without the monitoring option to reduce cost.
- The access control contractor never sees the original hardware schedule in full — they receive a device list and wire accordingly, leaving the monitoring conductors unused or unplanned.
- The strike gets installed, the door passes a visual inspection at rough-in, and the auxiliary switch wiring question does not come up until the access control commissioning report flags that the panel has no latch status for that opening.
By that point, adding monitoring capability requires either replacing the strike body entirely or confirming whether the installed unit has an unpopulated switch location that can accept a field-added module — a question that varies by product design and is not always answerable without pulling the unit out of the frame.
The Fire Door Compliance Layer That Raises the Stakes
A fail-secure electric strike on a fire-rated opening is there because the code requires it. Only fail-secure electric strikes can be fire-listed — a fail-safe configuration releases the latch on power loss, destroying the positive latching that NFPA 80 mandates for labeled door assemblies. The strike has a three-hour fire listing precisely because it is intended to hold a fire-rated opening in a positively latched condition under fire conditions.
If the access control system cannot confirm that the latch is engaged, the facility cannot demonstrate during an inspection or a Joint Commission survey that the fire door is functioning as required. The physical hardware may be code-compliant. The monitoring gap means the operational record is not.
For healthcare and school facilities in particular, this matters during:
- Annual fire door inspections required under NFPA 80
- Life Safety Code surveys (NFPA 101) in healthcare occupancies
- Access control system audits where door status records are reviewed
What to Check Before the Schedule Ships
If you are specifying or procuring fire-rated electric strikes for access-controlled openings, treat the monitoring option as a systems question, not a hardware line-item question. Before the schedule is finalized:
- Confirm with the access control contractor whether latch status points are allocated in the panel for each fire-rated strike location. If the panel scope does not include those points, monitoring hardware will be installed but never connected.
- Check the wiring plan for conductor count at each strike location. A monitored strike requires additional conductors beyond the solenoid supply leads. If the conduit was sized for a non-monitored configuration, adding monitoring later means a wire pull, not just a hardware swap.
- Verify that any alternate or substituted strike model carries the same fire listing and monitoring option as the specified unit. A heavy-duty, all-stainless, fire-rated strike with a monitoring auxiliary switch is a specific product configuration — not every strike in the same series ships with monitoring included by default.
- Document the decision in the hardware schedule if monitoring is intentionally omitted. The omission should be a deliberate choice reviewed by the specifier and the AHJ, not something that disappears quietly during procurement.
Preferred Alternatives for Heavy-Duty Fire-Rated Monitored Openings
When the opening demands a fire-rated, fail-secure electric strike with monitoring capability, DoorwaysPlus carries industrial-grade options in all-stainless construction suitable for high-abuse applications in schools, correctional facilities, healthcare buildings, and industrial plants. Heavy-duty strike designs rated for static strength well above standard commercial strikes, with endurance ratings in the millions of cycles, are available from lines that have demonstrated stability in parts and service support over time.
If your project has an existing frame prepped for a specific model and you are evaluating whether a comparable unit from a different manufacturer fits the same cutout, DoorwaysPlus can assist with dimensional comparison and fire-listing verification before you commit to a frame modification. Reach out with the existing frame prep dimensions and the lock function — cylindrical, mortise, or rim exit device — and we can help you find the right match.
The Short Version for Field Reference
- A door position switch does not replace latchbolt monitoring on a fire-rated electric strike opening.
- Only fail-secure configurations are fire-listable — confirm this before substituting any alternate model.
- The monitoring option must be coordinated between the hardware schedule and the access control wiring plan before rough-in.
- Dropping monitoring during value engineering creates a compliance documentation gap, not just a feature gap.
- If the installed strike does not have monitoring and the project requires it, replacement is usually the answer — field modifications are product-specific and not always available.
