Detail ATJ-EA FIXED TEMP / RATE OF RISE HEAT SENSOR - HOCHIKI

ATJ-EA FIXED TEMP/RATE OF RISE HEAT SENSOR

 

STANDARD FEATURES

SPECIFICATIONS

Low profile - Only 2.00" high, including base

Simple and reliable device addressing method

Uses the noise immune Digital Communication

Protocol (DCP), which utilizes interrupts for fast

response to fires

• Rate of Rise temperature threshold = 15°F/Min

(determined by panel)

• Adjustable threshold temperature = 135°F - 190°F

(determined by panel

SPECIFICATIONS

Operating Voltage 17 - 41 VDC

Standby Current 350ìA

Alarm Current 500ìA

Transmission Method DCP - Digital

Communication Protocol

Rate of Rise 15°F/Min. (8.3° C/Min.)

UL Temperature Range 135°F to 190°F

(57.2°C to 87.8°C)

Operating Temperature 32°F to 190° F

Range (0° C to 87.8° C)

Maximum Humidity 95% RH Non-Condensing

Color & Case Material Bone / White - ABS blend

Weight 3.2 oz

(4.9 oz. with 4" base)

Bases YBN-NSA-4, HSB-NSA-6,

ASB, SCI-B4 and SCI-B6

 

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.

 

OPERATION

The ATJ-EA incorporates a highly linear thermistor circuit.

The specially designed cover protects the thermistor

while allowing maximum air flow. The thermistor circuit

produces a voltage proportional to the temperature; this

information is transmitted to the control panel as a digital

value. When the ambient temperature exceeds a preprogrammed

threshold (fixed temp or rate of rise), the

sensor transmits an interrupt to the control panel

indicating a fire alarm. The fire alarm control panel can

adjust the sensor's fixed temperature threshold for

different installation requirements.

Up to 127 devices may be installed on each SLC loop.

The sensor address may be set by a hand-held

programming unit. The sensor mounts to an electronicsfree

base and incorporates a locking mechanism for

security. The base provides mounting slots, terminals

for field wiring and a third terminal for a remote indicator/

LED. The sensor has dual LEDs for easy viewing of the

sensor status.
