FWSG

Following are the specifications of an FWSG.

NOTE: Devices that do not meet the minimum signal strength or have an ambient noise level 
that exceeds the limit are not allowed to join the mesh network.

Choose a location for the FWSG that is clean, dry, and vibration-free. The area should be readily 

accessible with sufficient room to easily install and maintain the FWSG.  Metal obstructions that 

impede the radio frequency communication and should be avoided. Carefully unpack the system 

and inspect for shipping damage if any.  All wiring must comply with the national and local codes 

for fire alarm systems.
