DETECTION CIRCUIT CABLES (Continued)
Verify cable route from the control module to the detection
component end points conforms to the following rules (see
Figure 5-30):
• No Double Branching
• No EOL Devices on end of branch
• Branch must end with Detection Circuit Branch Terminator or
EMA
• If used, EMAs must be first component(s) on circuit
• Each EMA must be on a single use branch
• Linear Detector may be anywhere in the main trunk after the
EMA
• Main detection trunk must be terminated with EOL Device

SAMPLE - CORRECT DETECTION CIRCUIT INSTALLATION

Install Detection Circuit using the following rules:
1. An Electric Manual Actuator (EMA), if used, must be
installed prior to any other detection device. Install a Detec-
tion Circuit Tee and required length of Detection Circuit
Cable. See Figure 5-31.
2 Install each EMA on a separate branch (only one device on
a branch). See Figure 5-31.
3. Spot Thermal detectors can be installed in main trunk of
detection circuit or on a branch circuit using a Detection
Circuit Tee and Detection Circuit Cable. If installed on a
branch circuit, a Detection Circuit Branch Terminator (Part
No. 439398) must be connected to the last detector. See
Figure 5-32.
CAUTION
Do not terminate any branch with an EOL Device. Use
Branch Terminator only.
4. The Linear Detector may be installed anywhere in the main
detection circuit trunk after the EMA. If the last device, the
Linear Detector is terminated with an EOL Device. See
Figure 5-33.
