DETECTION CIRCUIT CABLES (Continued)
INCORRECT INSTALLATIONS
CAUTION
Do not use an EOL Device on a branch because complete
detection circuit will not be monitored. (See Figure 5-34 and
5-35).
Double branching is not allowed. (See Figures 5-34 thru
5-36). Failure to comply may cause the system to not function
properly.

CAUTION
Only one EMA may be installed from a detection circuit tee on a
single branch circuit. If multiple EMAs are to be installed, addi-
tional branches on the main trunk will be required (one EMA
per branch). Incorrect installations will cause the system to not
function properly. See Figure 5-36.

INCORRECT EMA INSTALLATION
009198
CAUTION
Install EMA(s) as the first component(s) on the Detection Circuit
and on a single use branch. Failure to comply may cause the
system to not function properly. (See Figure 5-37 and 5-38).
