The colour scheme used must be consistent across the installation. The table above shows suggested colour
codes for various cables. Where the construction is two twisted pairs, the data and power should be on
separate pairs.
Current drawn from an OS2 PER terminal is limited by fuse FH2 (Nominally 200mA). This fuse may be uprated
if multiple smoke detectors or other loads on per are used.
