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.
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.
The microprocessor in each detector provides four additional
benefits; self-diagnostics and history log, automatic device
mapping, stand-alone operation and fast, stable
communication.
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.
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:
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.
- 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

ADT-HRSI INTELLIGENT HEAT DETECTOR
Isolator Base ADT-IB, ADT-IBS:
Accessories:
This base includes a built-in line fault isolator. A detector
must be installed for it to operate. The integral isolator relay
is controlled by the detector or the loop controller. A
maximum of 96 isolator bases can be installed on one
circuit. The isolator base does not support the SIGA-LED
Remote LED.
All detector mounting bases have wiring terminals that are
accessible from the "room-side" after mounting the base to
the electrical box. The bases mount to North American 1-
gang boxes and to 3-1/2 in or 4 in octagon boxes, 1-1/2 in
(38 mm) deep. They also mount to European BESA and
1-gang boxes with 60.3 mm fixing centers.
The isolator operates as follows: a short on the line causes
all isolators to open within 23 msec. at 10 msec intervals,
beginning nearest the loop controller, the isolators close to
provide the next isolator down the line with power. When the
isolator next to the short closes, it reopens within 10 msec.
In Class A operation, the process repeats beginning on the
other side of the loop controller.
Removing a detector from its base (except isolator base)
does not affect other devices operating on the same circuit.
Standard Base SIGA-SB:
This is the basic mounting base for Honeywell Signature
Series detectors. The SIGA-LED Remote LED is supported
by the Standard Base.
Remote LED SIGA-LED:
Relay Base ADT-RB:
The remote LED connects to the SIGA-SB Standard Base
only. It features a North American size 1-gang plastic
faceplate with a white finish and red alarm LED.
This base includes a relay. Normally open or closed
operation is selected during installation. The dry contact is
rated for 1 amp (pilot duty) at 30 Vdc. The relay's position is
supervised to avoid accidentally jarring it out of position. The
relay base does not support the SIGA-LED Remote LED.
The relay is controlled by the detector and operates as
follows: at system power-up or reset, the relay is de-
energized.
SIGA-TS Trim Skirt:
Supplied with 4 in bases, it can also be ordered separately to
use with the other bases to help hide surface
imperfections not covered by the smaller bases.
When a detector is installed in the base with the power on,
the relay energizes for 4 seconds, then de-energizes. when a
detector is removed from a base with the power on, the relay
is de-energized. When the detector enters the alarm state,
the relay is energized.
Application:
Table 1 below shows six standard test fires used to rate the
sensitivity of smoke and heat detectors. The table indicates
that no single sensing element is suited for all test fires.
