Appendix 2: Recommended Cable Distances Using 7/0.2 Alarm Cable
in Serial Mode
Standard 7/0.2 alarm cable gives some limitation to the distance that a sounder may be wired away
from the control panel for reliable operation. To overcome this limitation increase the number of cores
used for the 0V and 12V feed to the sounder.

used for 0V connection
and 2 cores for the +12V
connection.
