GENERAL DESCRIPTION
The ESL 429/449 and 428/448 Series low-profile, self-diagnostic, two-
and four-wire smoke detectors work on the light scattering principle. A
pulsed infrared light-emitting diode serves as the light source, and a
high-speed photo-diode as the sensing element. This design has
superior protection against false alarms caused by dust, insects, RF
and ambient-light.
These Series of smoke detectors are especially suited for residential
occupancies, including hotels, motels and dormitories, as well as other
commercial and industrial fire-system applications. This Series is
designed for 2-wire and 4-wire connection, respectively, to 6-24 V DC
fire alarm control panels, UL Listed for commercial or household fire
protection.
