Addressable Photoelectric Detectors
Addressable Devices
DF-61010:A
General
The Fire-Lite SD365(A), SD365T(A), and SD365R(A) Series
addressable plug-in photoelectric smoke detectors are designed for
both performance and aesthetics. A new modern, sleek, contempo-
rary design and enhanced optical sensing chamber is engineered to
sense smoke produced by a wide range of combustion sources in
accordance with more stringent code standards.
Exclusively for use with Fire-Lite’s addressable fire alarm control
panels, the SD365(A) Series point ID capability allows each detec-
tor’s address to be set with rotary, decimal address switches, provid-
ing exact detector location for emergency personnel to quickly locate
a fire during its early stages, potentially saving precious rescue time
while also reducing property damage. Two LEDs on each sensor
light to provide a local, visible sensor indication.
The SD365(A) Series also offers 135°F (57°C) fixed temperature
thermal sensing on the SD365T(A) and a remote test capable detec-
tor on the SD365R(A) for use with DNR(A)/DNRW duct smoke
detector housings.
Features
SLC LOOP
• Two-wire loop connection.
• Unit uses base for wiring.
ADDRESSING
• Addressable by device.
• Rotary, decimal addressing: Please refer to the Fire-Lite panel
manuals for device capacity.
ARCHITECTURE
• New modern profile for improved aesthetics.
• Unique single-source design to respond quickly and dependably
to a broad range of fires.
• Integral communications and built-in type identification.
• Built-in tamper-resistant feature.
• Removable cover and insect-resistant screen for simple field
cleaning.
OPERATION
• Designed to meet UL 268 7th Edition.
• Factory preset at 1.5% nominal sensitivity for panel alarm thresh-
old level.
• Visible LED “blinks” when the unit is addressed (communicating
with the fire panel) and latches on in alarm.
• Low standby current.
MECHANICALS
• Sealed against back pressure.
• Mounts to: single-gang box, 3.5" (8.89 cm) or 4.0" (10.16 cm)
octagonal box, or 4.0" (10.16 cm) square electrical box (with or
without a mud ring - not included).
OPTIONS
• Remote LED output connection, RA100Z.
Installation
SD365(A) series plug-in detectors use a detachable mounting base
to simplify installation, service and maintenance.
Mount base (all base types) on an electrical backbox which is at
least 1.5" (3.81 cm) deep. For a chart of compatible junction boxes,
see DF-60059.
NOTE: Because of the inherent supervision provided by the SLC loop,
end-of-line resistors are not required. Wiring “T-taps” or branches are
permitted for Style 4 (Class B) wiring. SD365R(A) mounts in a
D355PL(A) or DNR(A) /DNRW duct detector housing.
Operation
Each SD365(A) Series detector uses one possible addresses on the
Fire-lite
Signaling Line Circuit (SLC). It responds to regular polls
from the system and reports its type and status.
Detector Sensitivity Test
Each detector can have its sensitivity tested (required per NFPA 72,
Chapter 14 on Inspection, Testing and Maintenance) when installed/
connected to an ES-50X or ES-200X addressable fire alarm control
panel. The results of the sensitivity test can be printed off the for
record keeping.
