Modular Construction
The D323A is part of a two‑piece modular design
photoelectric smoke detector assembly. Attach the D323A
to a D321A Analog Detector Base (6 in. [15 cm]) or a D336A
Analog Detector Base (4 in. [10 cm]) by inserting the
detector head into a groove on the base and turning the
head clockwise.
The base’s security locking tab prevents any unauthorized
head removal from the base.
Mounting
Smoke detectors are typically mounted on the ceiling.
However, if smoke detectors are mounted on a wall, they
must be at least 4 in. (10 cm), but no more than 12 in.
(30.5 cm), below the ceiling.
For UL Listing requirements, the spacing between detectors
should be no more than 30 ft (9 m).
Programming
The D323A’s address is set by programming an EEPROM
microchip located in the detector head. The D5070 Analog
Device Programmer is required for address setting.
