Before Installing
This detector must be installed in compliance with the
control panel system installation manual. The installation
must meet the requirements of the Authority Having Juris-
diction (AHJ). Detectors offer maximum performance
when installed in compliance with the National Fire Pro-
tection Association (NFPA); see NFPA 72.
General Description
Filtrex® uses a small air intake fan and a high density re-
placeable filter. Air and smoke are drawn into a photoelec-
tric sensing chamber while airborne particulate and water
mist are removed. The addressable-analog detector trans-
mits an analog representation of smoke density over a com-
munication line to a control panel. Rotary-decade switches
are provided for setting the sensor’s address. Two LEDs on
the sensor are controlled by the panel to indicate sensor
status.

WARNING
Filtrex requires compatible addressable communications
to function properly. Connect this detector to listed-com-
patible control panels only.
Filtrex is not designed to operate in explosive environments.

The unique design of Filtrex eliminates the need for typical
detector cleaning. The only maintenance necessary is re-
placing the filter, which is signaled by a trouble condition
at the panel (see below).

Figure 3. Test magnet position:
Filtrex has been designed to maximize the amount of time
before maintenance is required. Filtrex utilizes a replaceable
filter that may become clogged over time. Filtrex monitors
itself to insure that the filter has not become clogged. Be-
cause environmental conditions can vary significantly, the
amount of time before maintenance could vary significantly
as well. To fully understand the maintenance requirements
of Filtrex in its installed location, it is recommended that the
following test program be conducted.
TEST MAGNET
MARKER
1. Install Filtrex in the desired location.
2. Connect Filtrex to the fire alarm control panel.
3. Maintain a record for at least 90 days of any mainte-
nance performed on or required by Filtrex.
4. At the end of the test period, use the record to develop
and schedule maintenance. Filtrex detectors should be
serviced at regular intervals to insure that the fire alarm
system provides continuous protection.
Replacing the Filter
IMPORTANT:
When the filter becomes too clogged to draw ad-
equate air into Filtrex, power is automatically cut
from the detector, sending a trouble signal to the
fire control panel. After 5 minutes, power is re-
stored to the detector for 72 hours. After 72 hours,
power is cut again and the detector will remain off-
line until the filter is replaced.
Figure 4. Replacing the filter cover:
Note: The unit has two filters. The replaceable filter is in-
side the cover. A permanent filter is mounted to the unit.
1. Grasp the Filtrex housing with one hand and the cover
with the other. Turn the cover counterclockwise fully
(approx. 30 degrees) and remove cover by pulling it
away from detector unit (see Figure 4).
Cover is keyed to
fit into 4 matching
size slots.

NOTE: The base is equipped with an optional tamperproof
feature which can be used to prevent unintentional removal
of Filtrex while replacing the filter.

If a clogged filter was the cause of the trouble condition, Figure 5: Installing Filtrex detector into base:
normal detector operation should resume automatically
within five minutes. If the trouble condition persists, the
detector must be returned for repair or replacement.
Installing Filtrex Into Base
1. Align the detector at a right angle to the base, with the
five wires and connector adjacent to the connector re-
ceptacle as shown in Figure 5.
2. Plug the wired connector into the receptacle.
3. Rotate the detector into the base, making sure detector
and base keyed fit is lined up. Turn the detector clock-
wise until it snaps into place.
IMPORTANT: Filtrex will only operate with B501B-FTX/
B524FTXE Mounting Base.
