Here are some optimized guidelines for properly spacing PPA109s for emergency lighting projects:
PPA109 Density Recommendations
*Maintain a maximum 100:1 ratio of light controllers to PPA109s – Install at least 1 PPA109 for every 100 lights.
*For commercial spaces, install 1 PPA109 per 200 square feet of coverage area.
Examples:
*1-100 lights = Minimum 1 PPA109
*101-200 lights = Minimum 2 PPA109s
*10,000 sq ft space = Approximately 10 PPA109s (at 200 sq ft spacing)
Goals:
*Keep all fixtures within reliable wireless range of a PPA109 (max 100:1 ratio)
*Provide overlap between PPA109s for redundancy (200 sq ft spacing)
Properly distributing PPA109s using these spacing guidelines ensures robust mesh network coverage across the entire emergency lighting installation.
