Introduction
These instructions apply to all sensors listed on this Technical Bulletin for maintaining, cleaning and testing. Failure to
following these instructions may result in the failure of the sensors to initiate an alarm condition. Hochiki America Corporation
is not responsible for sensors that have been improperly maintained, cleaned or tested.
Features
ALN-V photoelectric smoke chamber detects smoldering/fast-flaming fires
ATJ-EA combination fixed/rate of rise heat sensing element detects both fixed/rate of rise temperature
ACC-V multi-criteria photoelectric smoke chamber and heat sensing element detects smoldering or fast-flaming fires
and fixed temperature
ACD-V multi-criteria photoelectric smoke chamber, combination fixed/rate of rise heat sensing element, and carbon
monoxide (CO) detects smoldering/fast-flaming fires, fixed/rate of rise temperatures, and poisonous carbon monoxide
(CO) gas.
The combination of a high signal-to-noise ratio and sensitivity stability make this sensor effective in a wide range of
environmental conditions
User programmable alarm thresholds
A reliable and fully digital transmission method, which is highly immune to noise
The control panel is able to verify the status of any device. Whether the device is dirty or approaching an alarm
condition, it can make this determination routinely
It is possible to assign a priority to any device that is deemed necessary by the nature of the systems design
There is an interrupt sequence, which can assign priority to fire and other similar signals
