Detection Circuit Cable (Red Connectors) (Continued)
INCORRECT DESIGN INSTALLATIONS
CAUTION
Do not use an EOL Device on a branch line because the
complete detection circuit will not be monitored. (See Figure
4-6 and 4-7). Double branching is not allowed. (See Figures
4-6 thru 4-8). 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 line. If multiple EMAs are to be installed, addi-
tional branch lines on the main trunk will be required (one EMA
per branch line). Incorrect installations will cause the system to
not function properly. See Figure 4-8.

INCORRECT EMA INSTALLATION

CAUTION
Install EMA(s) as the first component(s) on the Detection Circuit
and on a single use branch line. Failure to comply may cause
the system to not function properly. (See Figure 4-9, and 4-10).
