the Silent Knight SK
INTELLIKNIGHT ACCESSORY
SK-ACCLIMATE
An Intelligent Multicriteria Smoke Detector
A patented photoelectric sensing chamber and dual thermistor heat
detector combine with an array of on-board software tools, to maximize
fire detection.
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 to
your fire protection needs.
Description
The SK-Acclimate Multi criteria
Photoelectric Smoke Detector
incorporates both thermal and
photoelectric technologies that
interact to maximize detection.
An on-board microprocessor with
advanced software focuses on
rejecting nuisance alarms. The SKAcclimate is for use with Silent
Knight Intelliknight-series fire alarm
control panels (FACPs).
Using advanced software, SKAcclimate continuously samples the
air in the environment and adjusts
its detection parameters and alarm
threshold accordingly. And it does
this automatically, without user
intervention.
A dual stage drift compensation
feature reduces maintenance
frequency. SK-Acclimate offsets the
effects of gradual dust build-up and
will notify the control panel before
its compensation level is reached,
allowing time for maintenance.
Once the compensation limit is
reached, a second signal is sent to
the control panel indicating an
urgent need for maintenance.

Engineering Specifications
The contractor shall furnish and install where indicated on the plans, Multi criteria SK-Acclimate. Sensor shall
incorporate Photoelectric Smoke detection and a fixed temperature heat detector. The combination detector head,
and twist-lock base, shall be UL® listed compatible with Silent Knight’s IntelliKnight fire alarm control panels. The
base shall be the appropriate twist-lock base B210LP.
The 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 SK-Acclimate 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.
