Display Module Location (Continued)
NOTICE
The ambient temperature for the display
module location must not fall below –40
°F nor exceed 185 °F (–40 °C to 85 °C).
Note: If plans include an optional pneumatic manual actua-
tor in the operator’s compartment, confirm the operator has
access to the red strike button on the actuator. For detailed
planning/installation guidelines, refer to the appropriate system
manual (latest edition):
LT-A-101-10/20/30 Manual

CHECKFIRE 210 Circuit Cable Assemblies
Plan on routing circuit cable assemblies in accessible loca-
tions, protected from undue wear, damage, and heat. Cable
connectors should not be installed in areas where temperature
will exceed 221 °F (105 °C).
NOTICE
All circuit cables must be supported within 1
ft (305 mm) of each component connection
and a maximum of 3 ft (914 mm) between
supports with rubber-coated 5/16 in. (8 mm)
P-Clamps or double-loop cable ties.
When cables pass through a partition, use a bulkhead connec-
tor designed for the appropriate cables. Cables must never be
routed through a hole or near sharp edges without being prop
-
erly protected.

Display Cable
Detection Circuit Cable (Red Connectors)
Connects input devices to the CHECKFIRE 210 Interface
Control Module (ICM) such as:
• Electric Manual Actuators (EMA)
• Linear Detectors
• Spot Thermal Detectors
1. Determine appropriate detection method (linear detectors
or spot thermal detectors) and placement for specific cable
end points. Review specific requirements for each at
the end of this section.
2. Choose a path in accessible locations providing protection
from undue wear, damage, and heat. Keep cables as far
away as possible from equipment electric cables, partic
-
ularly power cables to and from generators and electric
motors; also avoid:
• Antennas and associated cables
• Fire hazard areas
• Areas exposed to mechanical damage
• Proximity to moving parts
• Areas subject to debris accumulation
• Areas exposed to high temperatures (turbo chargers,
exhaust equipment, etc.)
• Areas requiring access by equipment service and main
-
tenance personnel
3. Plan route for the cable from the ICM to the detection
component end points (note end points for cable lengths)
using the following rules (see Figure 4-1):
• Detection Circuit tees can only be installed on the main
trunk
• No double branching
• No EOL Devices on end of branch line
• Branch line 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 line
• Linear Detector may be used anywhere in the main
trunk after the EMA(s) (if installed)
• Main detection circuit trunk must be terminated with EOL
