For US commercial fire alarm contractors
A new detector is one kind of change. Revised notification, panel, interface or testing requirements also need to reach the person pricing the fire alarm scope. Trace each finding to the document that establishes it.
RevisionSignal supports your judgment. It may miss changes, and a finding still needs your review.
Early Access starts in Shadow Review. Verify findings against the source and continue your normal review process.
Describe your workflow in the access request. Leave out confidential drawings, specifications, and bid details.
Before sharing live files, confirm who can access them, which providers process them, and the retention and deletion terms.

Fire Alarm review scenarios
These scenarios describe the review workflow we are developing. They are not automated findings or a statement of currently supported detection coverage.
Added or relocated detectors, modules and notification appliances can change the device scope of a bid.
Review in context
Check the tag, location and legend. A changed symbol or label needs to be interpreted against the source set.
A panel or interface revision may affect listed equipment, connections or coordination with another contractor.
Review in context
Review the riser, equipment requirements and interface notes together; a device count alone does not explain the whole change.
An addendum can revise sequences, documentation, programming or acceptance-testing responsibilities.
Review in context
Compare the specification and sequence text with the scope included in your estimate.
Compare the fire alarm plans, device legends, riser and wiring diagrams, equipment schedules, specifications, sequences and addenda. Include referenced mechanical interfaces and the notes assigning installation, programming and testing responsibilities.
Your team stays in control. Verify source documents and continue your normal bid review.
