DEMCO Photoelectric Smoke Detector D-233 with its new sensor design incorporates an internal pulsing LED and a photo-diode at an obtuse angle, is ideal for applications where slow-burning or smouldering fires are likely.
The D-233 has an advanced solid- state, low-voltage, surface-mount circuitry and are designed for 2-Wire installation using the D32003 universal base. The detector head is installed into the base with a simple twist-lock action.
The 360-degree detector design permits smoke entry from any direction, and a unique sensing chamber that permits operation in open areas with air velocities from 0 to 300 fpm.
A fine wire mesh extending between offset ports in the exterior and interior walls screens insects from the chamber and obstructs light from passing directly to the interior part.
Certification/Listing-UL and CE.
•   Advanced detection and discrimination algorithms.
•   Advanced solid-state, low-voltage, surface-mount circuitry.
•   Suitable for the majority of application conditions.
•   Easy installation, testing and maintenance.
•   Sleek low-profile housing design.
•   Flashing LED in standby mode.
•   Robust and reliable sensor head.
•   Two red LEDs to allow 360-degree viewing.
•   A fine mesh insect screen protects the chamber area i.e. to avoid potential nuisance alarms.
•   Optional/integrated heat detector for D233-2H and D233-2HL models.
The D32003 and D34003 universal bases are designed for the D-133 and D-233 series of detectors. Both are electronics-free bases with 2 and 4 contact points respectively. Their simple and robust design allow detectors to be plugged in without any need for force - particularly useful when installing onto suspended ceiling. Being designed as a common base, both units allow detector inter­change within the series.
