Zigbee Maximum Distance Limits for PAS400/PAS600/PAS800

[Joshua_Luzon]

Firmware release notes for 1.2.0 and 1.3.1 provided the guidelines for Zigbee Green Power (IEEE 802.15.4) communication in terms of the limit for number of devices connected but not on the distance limitations. 

Can you provide the distance limits for ZGP for PAS series devices? Thanks

Hello Joshreginal,

• For PAS400,PAS600,PAS800 in a metallic panel without External  antenna :

Prerequisite: Wireless Output Power is set on Low Level as mentioned in Panel Server User guide (refer to warning page 47 of Panel Server user guide )  

Radio Frequency propagation is a physical phenomenon. Therefore, it is identical between a PowerTag Link and an ESXP Panel Server and all the rules explained in the guide wireless PoerTag system guide DOCA0194EN can be applied.

Obviously, it means:

• a maximum distance of 3 meters between the gateway and the wireless gateway
• No full metallic partition between them
• In case of switchboard with non-partitioned contiguous cubicles (example: Prisma/ Okken / Blokset ) : one gateway for 3 cubicles

• For PAS800 with IEEE802.15.4 External antenna :

It will be possible to connect an external antenna (ref PASA-ANT1) to Panel Server Advanced PAS 800 (not possible with PAS400 / PAS 600 !) to extend the IEEE802.15.4 network outside the switchboard and communicate with devices such as ambient sensor (example: CL110) located outside.

In this case, it will be possible to set the wireless output power on "High" level for the external antenna.

This kind of architecture is very new and some information about wireless performance  will be available in doc NNZ58425 (not yet published) .

Best regards.
