Specification of

ALN-V PHOTOELECTRIC SMOKE SENSOR

 

The contractor shall furnish and install where indicated

on the plans, photoelectric sensors Hochiki

America Model ALN-V. The combination sensor

head and twist lock base shall be UL listed compatible

with a UL listed fire alarm control panel.

 

APPLICATION

 

The Hochiki America ALN-V Photoelectric Smoke Sensor

is particularly suited to detecting optically dense smoke

typical of fires involving materials such as soft furnishings,

plastic, foam or other similar materials which tend to

smolder and produce large visible smoke particles.

Hochiki's unique design allows fast response to flaming

fires as well as smoldering fires while preventing false

alarms.

The detection chamber consists of a light-emitting diode

(LED) and photodiode arrangement. The chamber is

designed such that light emitted by the LED cannot

normally reach the photo diode. In the event of fire,

particles of smoke enter the chamber and scatter the

light. As the smoke level increases, the scattering effect

increases, causing more light to hit the photodiode. The

chamber contains a unique baffle design which allows

smoke to enter the chamber while preventing external

light from affecting the photodiode. The photodiode input

level is sampled to sense smoke density.

When the smoke density exceeds a preset threshold

the sensor transmits an interrupt to the fire control panel

indicating a fire condition. The fire alarm control panel

can adjust the sensor threshold to compensate for

contamination.

Up to 127 devices are permitted on each SLC loop. A

sensor address is set by a hand-held programming unit.

The sensor mounts to an electronics-free base and

incorporates a locking mechanism for secure installation.

The base provides mounting slots, terminals for field wiring

and a third contact for a remote indicator/LED. The sensor

incorporates dual LEDs for easy viewing of sensor status.

 

OPERATION

• Low profile - Only 2.00" high, including base

• Simple and reliable device addressing

• Automatic compensation for sensor contamination

• Built-in fire test feature

• Uses the noise-immune Digital Communication

Protocol (DCP), which utilizes interrupts for fast

response to fires

• Two built-in power/alarm LEDs

• Programmble non-polling LEDs

• Non-directional smoke chamber

• Vandal resistant security locking feature

• Removable smoke labyrinth for cleaning or

Replacement
