Description

Napco Firewolf FWC-FSLC-SMK Features:

• Low Profile – Only 2.0″ high, including base
• Simple and reliable device addressing method
• Automatic compensation for sensor contamination
• Built-in fire test feature
• Uses noise immune communication protocol that
  utilizes interrupts for fast response to fires
• Two built-in power/alarm LEDs
• Programmable Non-polling LEDs
• Non-directional smoke chamber
• Vandal-resistant security locking feature
• Removable smoke labyrinth for cleaning or replacement

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 that 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 alarm 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 loop. A sensor
address can be 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.
