4. Position actuator swivel body in desired orientation and
wrench-tighten to actuator base until preventor is held tight
in place. See Figure 5-29.
CAUTION
DO NOT ATTACH CABLE TO ELECTRIC-PNEUMATIC
ACTUATOR UNTIL TESTING IS COMPLETE.

dETECTION CIrCUIT CABLES
The Detection Circuit #1 and #2 Receptacles (red ID rings)
on the CHECKFIRE 210 ICM are starting points for detection
circuits. See Figure 5-30. Each Detection Circuit consists of a
main trunk and may add branch lines utilizing Detection Circuit
Tees on the main trunk.
Route and secure the Detection Circuit Cable following the
installation instructions under Cable Connectivity / Installation,
page 5-5.
Maximum total length of Detection Circuit Main Trunk plus
Linear Detector is 750 ft (228.6 m). For example: If Detection
Circuit Cable is 50 ft (15.24 m), then Linear Detector could be
up to 700 ft (213.4 m). Maximum length for individual branch
lines is 250 ft (76 m) (not included with main trunk limit).

Verify each cable route (#1 and/or #2) from the ICM to the
detection component end points conforms to the following rules
(see Figure 5-31):
• Detection Circuit Tees can only be installed on the main
trunk
• No Double Branching
• No EOL Devices on end of branch
• Branch line must end with Detection Circuit Branch Termina
-
tor or EMA
• EMAs must be first component(s) on circuit if used
• Each EMA must be on a single use branch line
• Linear Detector may be anywhere in the main trunk after the
EMA
• Main detection circuit trunk must be terminated with EOL

Install Detection Circuit(s) using the following rules:
1. An Electric Manual Actuator (EMA), if used, must be
installed prior to any other detection device. Install a
Detection Circuit Tee and required length of Detection
Circuit Cable. See Figure 5-32.
2. Install each EMA on a separate branch (only one device
on a branch). See Figure 5-32.
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 5-33.
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 EMA. If last device, the Linear
Detector is terminated with an EOL Device. See Figure
5-34.
