4.
Remove the batteries. See "Replacing the batteries" on
page 3.
Note:
If the smoke chamber is removed with the batteries
installed, the smoke alarm will go into alarm and sound
after a few seconds. If the control panel has not been put
into Sensor Test mode, the central station will be called
and the fire department will be dispatched unless the
alarm is canceled or you have contacted the central
station as advised in step 1.
5.
Slide a flat-blade screwdriver in the slot on the alarm cap
and gently push the handle down to pry the alarm cap up
and off. See Figure 4.
6.
Squeeze the optical chamber where indicated and pull it
up and away from the optical base and discard the
chamber. See Figure 5.
7.
Remove all dust and dirt from the optical base using
compressed air or a soft-bristled brush.
8.
Line up the new optical chamber with the optical base by
aligning the arrows on the optical chamber to the latches
on the optical base, and then snap the optical chamber
down into place.
9.
Replace the alarm cap. Align the alarm cap with the unit,
insert the cap, and then turn it clockwise (about 15
degrees) until it snaps into place.
10. Observing the proper polarity, replace the batteries and
the battery compartment cover.
11. Attach the alarm. Align the tab on the alarm with the arrow
on the base, insert the alarm, and then turn it clockwise
(about 15 degrees) until it snaps into place. See Figure 3.
12. Test the unit sensitivity. See "Sensitivity test" on page 3.
13. After all smoke alarm maintenance is completed, exit the
control panel from Sensor Test mode (refer to the specific
control panel installation instructions).
14. We recommend that a smoke test also be done to ensure
the complete system is working properly. See "Smoke
test" on page 2.
Note:
The control panel alarm and all auxiliary functions
should be verified for a complete test of the system.

Maintenance
The units are designed for easy field service and maintenance.
When installed and used properly, they require minimal
maintenance.
The units should be tested weekly.
When a unit requires maintenance, it extinguishes its LED and
sends a signal to the control panel as described in the
following table.
Signal
Action required
Trouble signal
Sensitivity range is too high and the unit needs
cleaning. See "Cleaning" on page 3. Panels
supporting this feature identify the trouble as
"Partial Obscurity" on system touchpad displays.
Low battery
Alarm batteries are low. Replace the batteries.
See "Replacing the batteries" on page 3.
Selecting a location
Selecting a suitable location is critical to the operation of
smoke alarms. This equipment should be installed in
accordance with NFPA 72. Figure 6 shows required and
additional locations.
