Division 28 Electronic Safety and Security
Manufacturer or Product Substitution in Division 28 Electronic Safety and Security submittals
Short answer
The submittal proposes a different manufacturer or product than the spec names, without an approved or-equal or substitution request. Default grade in Division 28 Electronic Safety and Security: Blocker.
The submittal proposes a different manufacturer or product than the spec names, without an approved or-equal or substitution request. This guide covers how it shows up specifically in Division 28 Electronic Safety and Security submittals.
What to look for in Division 28 Electronic Safety and Security
Fire alarm and security specs name specific system manufacturers. Mixed-manufacturer systems often create compatibility issues. Look for:
- Fire alarm control panel (FACP) manufacturer substitutions (Notifier/Honeywell, EST/Edwards/Carrier, Simplex/Johnson Controls, Siemens, Bosch, Silent Knight)
- Initiating device manufacturer (detectors, pull stations) must match FACP manufacturer for addressable systems
- Notification appliance manufacturer substitutions (System Sensor, Wheelock/Eaton, Gentex, Amseco)
- Access control system manufacturer substitutions (Lenel/Carrier, Software House, Genetec, Honeywell, HID)
- Video surveillance manufacturer substitutions (Axis, Hanwha/Samsung, Bosch, Pelco, Avigilon/Motorola)
- Intrusion detection panel substitutions (Bosch, DMP, Honeywell Vista/Ademco)
- Card reader and credential manufacturer substitutions (HID, ASSA ABLOY)
- Mass notification system manufacturer substitutions (Notifier, EST, AtlasIED)
How severe is it?
Default grade: Blocker. Drops to a Note if the submittal attaches an or-equal approval letter from the architect of record.
Deviation Check assigns a default per category and escalates or de-escalates based on the spec, always showing its reasoning. See the Division 28 severity rules.
What the PM should do
Treat this as a hold. Do not approve the submittal until the sub resolves it, either by providing the specified product and documentation or by routing an approved substitution or or-equal request. Return the relevant spec passage to the sub as a redline.

Frequently asked questions
Why does a fire alarm manufacturer substitution in a Division 28 Electronic Safety and Security submittal get flagged as a Blocker even when the replacement brand looks similar?
In addressable fire alarm systems, initiating devices must match the FACP manufacturer to communicate over the same signaling line circuit. A Notifier panel cannot address EST/Edwards detectors, and a Simplex/Johnson Controls panel cannot drive Siemens devices. Mixed-manufacturer addressable systems fail system-level UL listing, so the substitution blocks the project until the sub aligns to a single listed combination.
How do you evaluate a proposed access control or video surveillance manufacturer substitution in Division 28 Electronic Safety and Security submittals?
Check whether the proposed brand - Lenel/Carrier, Software House, Genetec, or Honeywell on the access side; Axis, Hanwha/Samsung, Bosch, Pelco, or Avigilon/Motorola on video - is the one named in the spec or has an approved or-equal letter attached. Without that letter, the substitution is a Blocker. Card reader credentials from HID or ASSA ABLOY must also match the panel ecosystem or the system will not enroll cards.
