APPLICATION
The Hochiki America ATJ-EA Fixed Temperature / Rate
of Rise sensors provide accurate temperature
measurement data to the fire alarm control panel. These
sensors are well-suited for environments where dust,
cooking fumes or other factors make the use of smoke
sensors impractical.
ENGINEERING SPECIFICATIONS
Heat sensors are installed in accordance with NFPA
(National Fire Protection Association) 72, the UL Listed
Spacing Requirements and the rules and regulations set
forth by the local authorities having jurisdiction. The contractor
shall furnish and install, where indicated on the
plans, Fixed Temp / Rate of Rise Automatic heat sensors.
