Detect smoldering fires quickly and get help fast
with IntelliKnight� photoelectric smoke detectors.
IntelliKnight addressable photoelectric smoke detectors are the clear choice for commercial settings where
smoldering fires are a threat. In addition to accurately detecting a smoldering fire, each SD505-APS
photoelectric detector has a unique address, which is recognized by the IntelliKnight panel. No precious seconds
are wasted in determining location of an alarm.
The SD505-APS compensates automatically for contamination in the environment. And detector testing is
simple—even from a remote site. Like other IntelliKnight detector models, the SD505-APS offers a low profile for
pleasing aesthetics. The IntelliKnight family of detectors has been designed to use a common base, Model
SD505-6AB, allowing complete application and placement flexibility. Combine all this with the features you've
come to expect from Silent Knight smoke detectors—easy installation, stable operation, RF/transient protection,
and vandal-resistant locking—and it adds up to a flexible solution for all your fire protection needs.
Model SD505-APS
Analog / Addressable
Photoelectric Type
Smoke Detector
The SD505-APS is particularly
suited to detecting dense smoke
typical of fires involving materials
such as soft furnishings, plastic,
foam or other similar materials
which tend to smolder and produce
large visible particles.
The detector features automatic
compensation for contamination
and a simple detector calibration
test procedure that can be run from
the panel or remotely (using the
WindowsTM based downloading
software).
Operation
The SD505-APS units made up of
an LED light source and a silicon
photo diode receiving element. In a
normal standby condition, the
receiving element receives no light
from the pulsing light source. In the
event or fire, smoke enters the
detector and light is reflected from
the smoke particles to the receiving
element.
The light received is converted into
an electronic signal. Under normal
conditions, the status LED blinks
approximately every 15 seconds,
indicating that the head is
communicating with the loop. The
LED lights continuously during the
alarm period.

Engineering Specifications
�
The contractor shall furnish and install where indicated on the plans, addressable photoelectric smoke detector
Silent Knight SD505-APS. The combination detector head, and twist-lock base, shall be UL� listed compatible
with Silent Knight's IntelliKnight fire control panels.
The base shall permit direct interchange with Silent Knight SD505-AIS lonization Smoke Detector, or SD505-
AHS Heat Detector. Base shall be the appropriate twist-lock base SD505-6AB.
The smoke detector shall have a flashing status LED for visual supervision. When the detector is actuated, the
flashing LED will latch on steady. The detector may be reset by actuating the control panel reset switch.
The calibration of the detector shall be capable of being selected and measured by the control panel without the
need for external test apparatus.
The vandal-resistant, security locking feature shall be used in those areas as indicated on the drawing. The
locking feature shall be field selectable as required.
The SD505-APS shall automatically perform a functional test of the detector. The test method shall simulate
effects of products of combustion in the chamber to ensure testing of detector circuits.
