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.

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.

Application
The detector can be electronically addressed by
D-APP Hand Held Programmer. Please refer to
D-APP Hand Held Programmer Installation and
Operation Manual for details.
