ESL 500 Series
Smoke Detector
Description
The ESL 500 Series Smoke Detectors offer 2-wire, 4-wire, 12VDC,
and 24VDC detectors for fire system applications.
Depending on the model, the smoke detector provides the following
features:
Detector/base lock
Discourages unauthorized removal of the smoke detector by requiring
a screwdriver to remove the detector from the base.
CleanMe®
Enables the control panel to receive a warning signal via a 505
module, or CleanMe compatible panel, indicating that the optical
chamber needs to be replaced. This feature is available on the 521/
528 Series 2-wire detectors only.
The detectors ship with the CleanMe feature turned off. To turn on
the CleanMe signal move DIP switch 2 on the back of the detector to
the “on” position. See Figure 1.
ON
1. On=A (6-12V) range
Off=C (12-24V) range
2. On=CleanMe signal on
Off=CleanMe signal off
(521/528 Series only)
Note
Turning the CleanMe signal
on without using the 505
module and/or compatible
panel will create a trouble
signal.

Self-diagnostics
Includes automatic sensitivity testing. Once a day and immediately
upon first power up, each 500 Series detector performs a full
diagnostic test that includes a dynamic test of the sensing chamber
and internal electronics. This meets NFPA 72 field sensitivity testing
requirements without the need for external meters.
Drift compensation
The detectors automatically adjust sensitivity, up to a maximum of
1.0%/ft., as the detectors become dirty.
Using the 2-wire 521/528 Series with a panel that does not have 2wire capabilities
The ESL 505 module can convert the 2-wire 521/528 Series to a 4wire input on the control panel. The 521/528 Series is UL Listed as
compatible with the 505 module and will be fully UL compliant with
any UL listed 24 VDC control panel and panels that do not operate
below 12V. Each 505 module will accommodate up to 20 ESL 521/
528 Series smoke detectors. See the 505 module installation
instructions for more information.
Selectable voltage range for UL 2-wir e compatibility
The 500 Series 2-wire smoke detectors have a DIP switch that allows
the installer to choose between 12/24V operation and 6/12V
