Cable Recommendations 

Standard 7/0.2 un-screened alarm cable 
should be used. 

The maximum recommended cable 
distance is 50m if you are using SAB mode 
and only TR for tamper monitoring (i.e. not 
both TR and TF). This can be increased to 
100m by doubling the 0V cores. 

The maximum recommended cable 
distance is 100m if you are using SCB 
mode, or both TR and TF for tamper 
monitoring.
