REPLACING THE FILTER
IMPORTANT:
When the filter becomes too clogged to draw adequate air
into Filtrex, power is automatically cut from the detector,
sending a trouble signal to the fire control panel. After 5
minutes, power is restored 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.
NOTE: The unit has two filters. The replaceable filter is inside 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).
2. Replace with new filter and cover assembly. The cover
is keyed so it fits in place only one way. Turn the cover clockwise
until it stops.
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, nor-
mal 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 receptacle 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 clockwise until it
snaps into place.
