The system can be configured to operate with 1, 2, 3 or 4 snow sensors.
Each snow sensors must have different MAC address in order to communicate with the main board.

with unique MAC address as follows:
PYROSENSE
MAC Address 1
PYROSENSE2
MAC Address 2
PYROSENSE3
MAC Address 3
PYROSENSE4
MAC Address 4
The snow sensors will control zones
upon the following logic:

Notes:
- The number of snow sensors connected must be configured in section P09 of the technician settings.
- When one of the snow sensors cannot be viewed through communication (faulty or not connected),
the values on snow sensor 1 will be used instead.
The PYROSENSE is supplied with:
1. A plastic cap, to protect the sensor from dust and debris for when the sensor
is not in use (off season).
Important! The protective cap must be removed before use of the sensor.
If the protective cap is not removed, the sensor will not detect snow!
2. Plastic spikes, to be used if necessary, to keep birds off the sensor.
