Aritech DP721T User Manual

2 / 28 P/N 10-4226-501-1C70-09 • ISS 08JUN21
Always test detectors after installation.
Note: Please note that all models in the 700 Series are polarity
insensitive. Polarity must be observed when using remote
indicators.
Maintenance
To remove a locked detector:
1. Insert a small screwdriver into the locking tab
slot (Figure 2).
2. Press in and rotate the detector anticlockwise.
All detectors ship with a plastic dust cover. Smoke detectors
will not work with the dust cover in place. It must be removed
when installation is completed, before testing.
To replace the optical chamber:
1. Remove the detector head from the mounting base.
2. Remove the detector cover by inserting a screwdriver and
lifting as shown in Figure 3.
3. Remove the used optical chamber from the detector
(Figure 4) and insert the replacement optical chamber.
4. Replace the detector cover by placing onto detector head
and pushing down until it clicks into place. Install the
detector back into the mounting base.
5. Test the detector according to local regulations and verify
that it signals an alarm at the control panel.
To clean the optical chamber, follow the above instructions for
removal and use compressed air to clear the dust.
Caution: After replacing or cleaning the optical chamber,
check for sensitivity with the sensitivity level test described
below.
Testing
For in-depth sensitivity testing, see sensitivity level test mode
in Table 2 below. The test is initiated by holding a magnet to
the integral reed switch, marked by the word TEST on the
detector housing. The test results are indicated by the number
of times the LED flashes, as shown. Reset the detector once
testing is completed.
