Multi-building campuses break the AHA 3-minute rule’s single-building assumption. A high school with a separate gym, athletic field, and auditorium can’t be covered by an AED in the main building, inter-building walking time alone exceeds 90 seconds. This article frames the math and the standardization playbook.
The campus coverage rule
Each building is treated as its own AHA 3-minute zone. Inter-building travel time disqualifies a “shared” AED from satisfying coverage in either building. Standard pattern:
- 1 AED minimum per building
- Additional units per building per single-building sq ft math
- 1 dedicated AED per outdoor athletic field
- 1 dedicated AED at each significant public-access entry
Coverage by campus type
K-12 school district (5 to 15 schools)
Each school = its own deployment. Standardize across the district for procurement leverage. Typical: 2 to 4 AEDs per school (1 per building plus 1 per athletic field), so 30 to 60 across 15 schools. Annual fleet program costs $8,000, $15,000.
University campus (academic + athletics + residence)
50 to 500+ AEDs typical. Centralize through campus safety + per-building coordinators. Standardize on a single brand. Pair with athletic facility CPR-feedback variants. See College AED guide.
Multi-tenant corporate park
Property owner deploys building-level AEDs in lobbies + amenity floors; tenants deploy their own per their EAP. Coordination documented in the property safety plan.
Hospital system (multi-facility)
50 to 200+ AEDs across acute care + ambulatory + clinic sites. Standardize public-access AEDs for non-clinical areas (e.g. LIFEPAK CR2 or ZOLL AED Plus); clinical units use manual defibrillators. Fleet management software like AEDTS standard.
Religious campus (multi-building)
1 per main worship space + 1 per education building + 1 per fellowship hall. Volunteer response team training (see house of worship placement).
Procurement standardization
The single biggest financial leverage in campus deployment is standardizing on one AED brand + one cabinet model + one training partner. Volume discounts of 15 to 25% apply at 25+ units. Consolidate annual consumable orders to capture maximum pricing.
Fleet management threshold
At ~15+ AEDs across 3+ buildings, dedicated fleet management software pays for itself in reduced missed expirations and automated compliance reporting. See Multi-Site AED Fleet Management Guide.

Frequently Asked Questions
Can one AED cover multiple buildings?
Generally, no inter-building walking time alone exceeds the 90-second retrieval window. Each building needs at least one.
How many AEDs does a typical 10-building school district need?
20 to 40 units typical, or 2 to 4 per school: 1 per school + 1 per athletic field + extra for large high schools.
Should we standardize on one brand campus-wide?
Yes, captures 15 to 25% volume discount + simplifies consumable inventory + reduces training complexity.
When does fleet management software become worth it?
Around 15+ AEDs across 3+ buildings. Below that, spreadsheet + calendar suffices.
How do we coordinate AEDs in a multi-tenant property?
Property owner deploys building-level units; tenants deploy their own. Coordinate via the property safety plan.
