DEMCO Photoelectric Smoke Detector D-213 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-213 has an advanced solid-state, low-voltage, surface-mount circuitry and are designed for 2-Wire installation using the D3X001 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.
