Velociti™ Series
Harsh Environment Analog Addressable
Photoelectronic Smoke Sensor
The Gamewell-FCI Velociti™ Series, ASD-FILTREX-F
photoelectronic analog addressable smoke sensor provides early warning smoke sensing in harsh environments
where traditional smoke sensors are impractical.
The ASD-FILTREX-F sensor combines traditional smoke
photoelectronic sensing technology with a unique smoke
sampling system. A small intake fan draws air and smoke
into the sensing chamber where a filter removes airborne
contaminants and water mist from the air. Two (2), high
density filters remove particulate as small as 25 microns.
One filter can be removed for field cleaning, while the second filter is permanent and provides sensor protection during cleaning. The fan cycles on and off in a 15% duty cycle
to increase service life and reduce current consumption.
The air delivery system is fully supervised, with internal
circuitry to detect a clogged filter, fan failure, loss of power
or communications. If a filter clogs, the user is alerted to
service the unit. Power-up is automatic when the unit is
The Velociti™ Series use a communication protocol that
substantially increases the speed of communication
between the sensors and certain Gamewell-FCI analog
addressable fire alarm controls. These devices operate in
a grouped fashion. If one of the devices in the group has a
status change, the panel’s microprocessor stops the group
poll and concentrates on the single device. The net effect
is response speed up to five times greater than earlier
• Suited for harsh environments.
• High performance filter removes particulate of 25
• Compatible with most Gamewell-FCI analog addressable series fire control panels.
• Bicolor LEDs flash green whenever the sensor is
addressed, and light steady red on alarm.*
Note: Only the red LED is operative in panels that do not operate
in Velociti™ mode.
Ordering Information
This feature allows the sensor to sense smoke while
remaining unaffected by dust, dirt or occasional water
over-spray encountered in hostile environments, which
otherwise would create nuisance alarms or “very dirty”
indications in regular analog sensors. The rugged construction makes the sensor resistant to water spray where
occasional hosing-down cleaning is performed.
