Interlogix 511C Installation Instructions And Use

ESL 500 Series
Smoke Detector

Installation Instructions

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.
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 2-
wire capabilities
The ESL 505 module can convert the 2-wire 521/528 Series to a 4-
wire 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-wire 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
operation. See Figure 1 and Specifications.

Selecting a Location
Selecting a suitable location is critical to the operation of smoke
detectors. This equipment should be installed in accordance with
the National Fire Protection Association's (NFPA) Standard 72.
A-8-1.2.1.a Where to Locate the Required Smoke Detectors in
Existing Construction. The major threat from fire in a family
living unit occurs at night when everyone is asleep. The
principal threat to persons in sleeping areas comes from fires in
the remainder of the unit. Therefore, a smoke detector(s) is best
located between the bedroom areas and the rest of the unit. In
units with only one bedroom area on one floor, the smoke
detector(s) should be located as shown in Figure 2 A.
In family living units with more than one bedroom area or with
bedrooms on more than one floor, more than one smoke detector
is required, as shown in Figure 2 B.
