Access slot for tamper-
resist mechanism
Description: The Intelligent Fixed-Temperature Rate-of-Rise Heat
Detector (SIGA-HRS) is a component of the Signature Series. This
intelligent analog device contains rate-of-rise and fixed-temperature
heat sensors to detect fire. The heat sensors monitor the temperature
of the surrounding air and the detector analyzes the data from both
sensors to determine whether an alarm should be initiated. The rate-of-
rise heat sensor can quickly detect a fast, flaming fire. The fixed-
temperature heat sensor detects fire when the air temperature near the
detector exceeds the alarm point. A heat detector by itself, however,
does not provide life safety protection. For life safety situations, a heat
detector should be used in conjunction with ionization or photoelectric
smoke detectors or a combination thereof.
LEDs: The SIGA-HRS provides two LEDs that show detector status.
• Normal: Green LED flashes
• Alarm: Red LED flashes
• Standalone alarm: Green and red LEDs glow continuously
Electronic addressing: The loop controller automatically assigns
addresses to the detector. Custom addresses can be assigned to the
detectors via laptop computer. No addressing switches are used.
Stand-alone operation: If isolated from the loop controller, the
detector alarms when heat levels exceed preset values. See the
applicable control panel manual to verify standalone capabilities.
Self-diagnostics: The SIGA-HRS contains a microprocessor capable
of performing comprehensive self-diagnostic tests and storing results.
Details such as hours of operation, last maintenance date, sensitivity
values, and number of alarms and troubles are stored in nonvolatile
memory. These statistics may be retrieved and reviewed as desired.

Warnings
1. This detector will not operate without electrical power. As fires
frequently cause power interruption, we suggest you discuss
further safeguards with your local fire protection specialist.
2. This detector will not sense fires that start in areas where heat
cannot reach the detector. Heat from fires in walls, roofs, or on the
opposite side of closed doors may not reach the detector.
3. This detector is intended for use with ionization and/or
photoelectric smoke detectors. The heat detector by itself does not
provide life safety protection.
4. This detector will not detect oxygen levels, smoke, toxic gases, or
flames. This device should only be used as part of a broad based
life safety program which includes a variety of information sources
pertaining to heat and smoke levels, extinguishment systems,
visual and audible devices, and other safety measures.
5. Independent studies indicate that heat detectors should only be
used when property protection alone is involved. Under no
circumstances should heat detectors be relied on as the sole
means of fire protection.
6. Maintenance (regular or selected) should be planned in
accordance with the requirements of the authority having
jurisdiction to ensure proper operation. Refer to NFPA 72 and ULC
Standard CAN 536.
See Technical Bulletin P/N 270145 for additional information and
for cleaning instructions.
7. The bright orange-colored dust cover (supplied) must remain on
the detector during installation, and then be removed prior to
operation. The dust cover is not a substitute for removing the
detector during new construction or heavy remodeling.
8. To ensure proper operation, store the detector within the
recommended ranges. Allow the detector to stabilize to room
temperature before applying power.
Installation instructions
1. Push a small screwdriver into the tamper-resist access slot and
rotate the detector counterclockwise to remove it. Note: You can
permanently disable the tamper-resist mechanism by breaking and
removing the plastic lever arm from the base.
2. See the Technical Bulletin for installation guidelines.
3. Install and wire the base as described in the Installation Sheet
supplied with the base.
4. Peel off the removable serial number label from the detector and
apply it to the appropriate location in the serial number logbook.
5. Connect the detector to the base by rotating the detector clockwise
until it snaps into the locked position.
6. NFPA code requires that a calibrated sensitivity test be performed
upon completion of the original installation and following any
modifications or additions to the system. The Signature Series can
perform this test and generate a system sensitivity report.
7. In Canada your installation must meet the requirements of
CAN/ULC-S524-M91: Standard for the Installation of Fire Alarm
Systems, and the local authority having jurisdiction.
8. Before initial testing, remove the dust cover from the detector and
notify the proper authorities that the fire alarm system is
undergoing maintenance and will be temporarily out of service.
