ESL 500N Series
Low-profile two- and four-wire photoelectric smoke detectors
Overview
The ESL 500N series two- and four-wire conventional photoelectric
smoke detectors bring together trusted technology and a full line of
features to meet the demands of every type of application. The 500N
offers sounder models in two- and four-wire applications, specifically
to meet residential code requirements. The 521NCSXT has the
additional benefit of low current draw which makes it compatible with
a wide variety of control panels. The ESL 500N series also offers
choices for optional auxiliary relays and isolated heat sensors, not
available before in the ESL 500 series.
ESL offers CleanMe®, dust compensation, field replaceable optical
chambers, multiple criteria heat algorithms, and self-diagnostics
features.
Outstanding Features
The ESL 500N series 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 agains false/nuisance alarms caused by dust,
insects, RF, and ambient light. The proprietary optical chamber is field
replaceable.
A confirmed alarm causes the LED to light continuously. The unit
indicates trouble by flashing the LED every second. This meets the
NFPA 72 field sensitivity testing requirements. Units with built-in
85dBa sounders emit a temporal 3 pattern when in alarm and will emit
a steady tone when the input power is reversed.
All wiring terminates in clamp-type screw terminals. The detectors
mount to a standard single-gang electrical box, a 4-inch octagonal
box, a 4-inch square electrical box, or WIREMOLD No. 5739 fixture
box.
