SYSTEM DESCRIPTION
The CHECKFIRE 110 Detection and Actuation System is typi-
cally used with an ANSUL A-101 or LVS Vehicle Fire Suppres-
sion System for 24-hour protection of equipment. The system
is designed for vehicles in extreme environmental and physical
conditions.
Industries Where Vehicles Use CHECKFIRE 110 Systems:
• Forestry
• Agriculture
• Construction
• Public transportation
• Public utilities
• Land fills
• Waste disposal
• Mining
The automatic detection and actuation system provides moni-
tored input/output circuits to activate an ANSUL fire suppres-
sion system. On detecting a fire condition, the control module
activates the release circuit resulting in the discharge of an
expellant gas cartridge initiating fire suppression system opera-
tion. Optional pneumatic actuation is available.
CHECKFIRE 110 Features
• Supervised power, detection, and release circuits
• External primary power with an internal reserve power
source
• Selectable release time delay
• Electric “DELAY/Reset/Silence” button
• “PUSH To Activate / Alarm When Lit” electric manual activa-
tion button
• Color-coded “Plug and Play” connections
• 85 dB Internal Sounder
• System isolate feature
• Dust and water tight (IP67 rated)
