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.
*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)
*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.
What gauge would be needed to ensure that a 500 ft run between the test button and the PPA109s module?
Here are some optimized recommendations for connecting a remote test button to PPA109S over long distances:
For spans up to 500 feet between the test button and PPA109S, we suggest the following:
*Use 14 AWG or 12 AWG wire for the button connection. The larger wire gauge minimizes voltage drop over long cable runs.
*Install a dry contact relay near the test button, then use a thinner gauge wire from the relay to the PPA109S. This allows the relay to isolate and extend the contact over greater distances.
The key goals are:
*Maintain strong signal integrity from the button to the PPA109S.
*Avoid excessive voltage drop through thinner gauge wires over long cable lengths.
By using a heavier gauge wire or remote relay, you can reliably connect test buttons to PPA109S located up to 500 feet away.
Our testing has shown the PPA109 can reliably control lights at distances of up to 15 meters (49 feet).
15 meters is not the absolute upper limit, but we recommend maintaining a distance of 15 meters or less between a PPA109 and the lights it controls for optimal reliability.
Factors that can affect maximum distance include:
*Obstructions between the PPA109 and lights
*Building materials that interfere with wireless signals
*Highly congested wireless environments
Under ideal conditions, PPA109s may be able to reach further than 15 meters. However, limiting the distance to 15 meters or less helps ensure consistent communication and control.
