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  
DESCRIPTION  
- 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.  
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.
