Description
Mircom’s Acclimate™ Intelligent Multi-Criteria Sensor
uses advanced software to continuously sample
the air in an environment and adjust its detection
parameters and alarm threshold accordingly. It does
this automatically, without user intervention. There’s
no need for an installer to set sensitivity levels at
the control panel – Acclimate™ makes the educated
decisions. The Multi-criteria Detection Reduces
Nuisance Alarms.
Mircom’s new multi-criteria sensor, Acclimate™,
is an intelligent sensor in more ways than one.
First, it incorporates both thermal and photoelectric
technologies that interact to maximize detection.
Second, an on-board microprocessor and advanced
software focus on rejecting nuisance alarms.
A patented photoelectric sensing chamber and dual
thermistor heat detector combine with an array of
onboard software tools, to maximize fire detection. In
a real fire, the smoke and heat sensors work together
to make the quickest possible decision. The photo
sensor is optimized for smouldering fires, the heat
sensors provide a faster response to flaming fires. A
dual stage drift compensation feature reduces
maintenance frequency.
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.
Installation
Operation
Mircom’s Acclimate™ Sensor can be configured by
the compatible Fire Alarm Control Panels for distinct
methods of operation:
Full Multi-Criteria Integration
This method of operation allows for the Acclimate™
Sensor to provide full multi-criteria functionality.
Time Selective Detection Sensor
This method of operation allows for the smoke sensor
portion to remain off during the configured day period
and turn on during the configured night period to
provide full Acclimate protection. The heat sensor is
configured as an alarm input to provide continuous
alarm protection. This method of operation works in
conjunction with the compatible Fire Alarm Control
Panels for “Day/Night” mode.
Typical Application
A typical application for this mode of operation is a
public corridor or smoking lounge. These environments
normally have a high level of product of combustion
present which would cause a smoke sensor to false
alarm. At night these products of combustion do not
exist and the added protection of a smoke sensor can
be utilized.
Dual Functionality In One Package
This method of operation allows for the heat sensor
portion to be configured as an alarm input and the
smoke sensor portion to be configured as a supervisory
(latching/non-latching), trouble or monitor input. This
allows the smoke portion of the sensor to act as a local
intelligent smoke alarm with an optional sounder base.
The heat sensor is configured as an alarm input to
provide continuous alarm protection. This method of
operation allows for one sensor to provide two different
modes of operation, each with a distinct programmable
message.
Typical Application
A typical application for this mode of operation is
a hotel room where the smoke sensor acts as an
addressable smoke alarm with a local sounder. The
smoke sensor provides a local alarm while initiating
an alert signal and annunciation point at the fire alarm
control panel. The heat sensor acts as an addressable
system alarm device which when activated initiates a
general alarm.
