Description
D-A410 Intelligent Combination Heat/Photoelectric
Smoke Detector integrates photoelectric detection and
fixed temperature and rate of rise detection technology
by combining smoke sensor and heat sensor in
mechanism and circuitry structure. Just because of the
combination of smoke detection and heat detection,
D-A410 detector not only overcomes the disadvantage
that detectors using common infrared scattering
technology are insensitive to black smoke with small
particles, but also can pick up fire with obvious rise of
temperature such as alcohol flame, thus extending its
application range.
Connection and Cabling

Recommended Cabling
1.0 mm2 or above fire cable for detector loop, laid out
through metal conduit or flame-retardant conduit.
Subject to local codes.
Installation
A fixed installation direction is ensured by the location
elements on the detector and the base. Fix the base
with two tapping screws, and then align mark C on the
detector with A on the base, rotate the detector to align
mark C with mark B (Refer to Fig. 1 and 2 for the
position of the marks), the detector will be fitted to the
base.
Mounting of the detector is shown in Fig. 3.

Maintenance
The detector should be installed just before
commission and kept well before installation.
Corresponding measures should be taken for
dust-proof, damp-proof and corrosion-proof.
Dust covers are an effective way to limit the entry
of dust into smoke detector sensing chambers.
Therefore, the dust cover should not be removed
until the building starts to be used.
Clean the detector at least once 1 year to ensure
normal operation of the system.
If unwanted alarms are often found of the detector
on site, the sensing chamber should be cleaned.
Power must be removed from the detector before
cleaning.
Before cleaning the detector, notify the proper
authorities that the system is undergoing
maintenance and will be temporarily out of service.
Disable the zone or system undergoing
maintenance to avoid any unwanted alarms.
The detector should be tested again after cleaning
and re-installing. Notify the proper authorities
when the system is back in service.
Fire simulation test should be done to the detector
at least once 6 months.
