ADT-HRSI
Intelligent Heat Detector
SPECIFICATION DATA
DESCRIPTION
Honeywell's Signature Series Model ADT-HRSI Intelligent
Heat Detectors gather analog information from their fixed
temperature and/or rate-of-rise heat sensing elements and
converts it into digital signals. The detector's on-board
microprocessor measures and analyzes these signals. It
compares the information to historical readings and time
patterns to make an alarm decision. Digital filters remove
signal patterns that are not typical of fires. Unwanted alarms
are nearly eliminated.
The microprocessor in each detector provides four additional
benefits; self-diagnostics and history log, automatic device
mapping, stand-alone operation and fast, stable
communication.
Self-diagnostics and History Log:
Each Signature Series detector constantly runs self-checks
to provide important maintenance information. The results
of the self-check are automatically updated and permanently
stored in the detector's non-volatile memory. This information
is accessible for review any time at the control panel, PC, or
by using the SIGA-PRO Signature Program/Service Tool.
The information stored in the detector's memory includes:
- Detector serial number, address, and type
- Date of manufacture, hours of operation, and last
maintenance date
- Current detector sensitivity values and the extent of
environmental compensation
FEATURES
• 70ft (21.3 meter) spacing
• 9°C (15°F) per minute rate-of-rise and 57°C (135°F)
fixed temperature alarm threshold
• Intelligent detector with integral microprocessor
• Non-volatile memory
• Automatic device mapping
• Electronic addressing
• Identification of defective detectors
• Twin status LEDs
• Standard, relay, and fault isolator mounting bases
• Designed and manufactured to ISO 9001 standards
- Original detector sensitivity values upon manufacturing
- Number of recorded alarms and troubles
- Time and date of last alarm
- Analog signal patterns just before the last alarm
- Up to 32 possible trouble codes which may be used to
diagnose faults.
In the unlikely event that an unwanted alarm does take place,
the history file can be called up to help isolate the problem
and prevent it from happening again.
Automatic Device Mapping:
The loop controller learns where each device's serial number
address is installed relative to other devices on the circuit.
This "mapping" feature provides supervision of each device's
installed location to prevent a detector from being reinstalled
(after cleaning etc.) in a different location from where it was
originally. The history log for the detector at its original
location remains relevant and intact.
The Signature Series Data Entry Program also uses the
mapping feature. With interactive menus and graphic
support, the wired circuits between each device can be
examined. Layout or "as-built" drawing information showing
wire branches (T-taps), device types and their address are
stored on disk for printing hard copy. This takes the "mystery"
out of the installation. The preparation of "as-built" drawings
is fast and efficient.
