Alarm Application – Operator Safety
Most vehicles are very noisy, and parts of the vehicle are not
visible; often the operator is not aware a fire exists. A high
decibel alarm and flashing strobe may help warn the oper
-
ator the CHECKFIrE 110 Control Module is actuating the
fire suppression system. Use the Pressure switch (Part No.
440090) for connections to remote alarming devices (provided
by others). For safety, evacuate the vehicle at the earliest
possible moment.
The control module pulsing lEDs and 85 dB sounder are
intended to alert the operator when the unit receives a fault
signal or detection input from a detection device (before actuat-
ing the fire suppression system).
The Alarm Circuit 3.3 VDC digital output from the control
module connects to compatible vehicle electronics (i.e.
computer) for notification of an Alarm or Fire condition.
SPECIFIC PLANNING INFORMATION
review the following information to plan the CHECKFIrE 110
system layout. Create a drawing of the proposed plan showing
locations of components and cable on the vehicle. This will
help avoid unforeseen installation problems. Once an accept-
able layout is complete; record and keep it for future reference.
Control Module Location
1. Mount control module in full view, easily accessible, and
within reach of the operator. select a flat surface that will
properly support the control module during all vehicle oper-
ating and environmental conditions (e.g., shock and vibra-
tion). Note:
The control module should never be mounted in
an area subject to pressure washing or steam cleaning.
2. Confirm the operator has access to the “PUsH To Activate /
Alarm When Lit” and the “DELAY/Reset/Silence” buttons.
3. Select a location suitable for surface mounting (3/16 in.
(4.7 mm) maximum thickness), or bracket mounting. For
bracket mounting, use the optional CHECKFIRE 110/210
Mounting Bracket (Part No. 439564) and secure with
screws or bolts. The mounting surface must be flat to avoid
strain on the mounting bracket.
4. Confirm access for proper wiring connections, periodic
inspection, and maintenance. If surface mounted, access to
the underside or rear of the mounting surface is necessary.
review the surrounding area to confirm the location will not
interfere with normal vehicle equipment maintenance or
operation.
NOTICE
The ambient temperature for the control
module location must not fall below –40 °F
nor exceed 140 °F (–40 °C to 60 °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
(Part No. 24327)

CHECKFIRE 110 Circuit Cable Leads and 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 cable 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.
