SIGA2-HRS Intelligent Fixed-Temperature and
Rate-of-Rise Heat Detector Installation Sheet
Description
The Signature Series model SIGA2-HRS Intelligent Fixed-
Temperature and Rate-of-Rise Heat Detector is an intelligent
device that contains a rate-of-rise and fixed-temperature heat
sensor to detect fire. The heat sensor monitors the
temperature of the surrounding air and the detector analyzes
the data from the sensor to determine whether to initiate an
alarm. The rate-of-rise heat function quickly detects a fast,
flaming fire. The fixed-temperature heat function detects fire
when the air temperature near the detector exceeds the alarm
point.
LED indicator. The LED indicator (see Figure 1 below)
displays the following states:
•Normal: Green LED indicator flashes, no action.
•Alarm/active: Red LED indicator flashes, evacuate the
area.
•Stand-alone alarm: Red LED indicator turns on, evacuate
the area.

Installation
Notes
•This detector does not operate without electrical power. As
fires frequently cause power interruption, discuss further
safeguards with the local fire protection specialist.
•This detector does not sense fires 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.
•This heat detector by itself does not provide life safety
protection. Use this detector with ionization or
photoelectric smoke detectors, or both.
•This detector does not detect oxygen levels, smoke, toxic
gases, or flames. Use this device 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.
•Independent studies indicate that heat detectors should
only be used when property protection alone is involved.
Never rely on heat detectors as the sole means of fire
protection.
•To ensure proper operation, store the detector within the
recommended ranges. Allow the detector to stabilize to
room temperature before applying power.
•The dust cover (supplied) must remain on the detector
during installation and be removed prior to commissioning
and service. The dust cover is not a substitute for
removing the detector during new construction or heavy
remodeling.
•In Canada, install according to CAN/ULC-S524 Standard
for the Installation of Fire Alarm Systems, CSA C22.1
Canadian Electrical Code, and the local authority having
jurisdiction.
•To permanently disable the tamper-resist mechanism prior
to placing the detector in difficult to reach locations, break
and remove the plastic lever arm from the base. See
Figure 1, item 1.

To install the detector:
1. Install and wire the base, as described on the installation
sheet supplied with the base.
2. Remove the serial number label from the detector and
attach it to the project documentation.
3. Attach the detector to the base by rotating the detector
clockwise until it snaps into the locked position.
Testing
Before testing, notify the proper authorities that the fire alarm
system is undergoing maintenance and will be temporarily out
of service.
Caution: Heat damage. Excessive heat may damage the
detector outer cover. Do not apply excessive heat when using
a hair dryer. When using a Testifire detector tester, you must
install a SIGA2 Testifire Adapter Assembly.
Make sure the SIGA2 Testifire Adapter Assembly (model
SIGA2-TSTSPACER) is installed in the Testifire detector tester
before testing. Refer to the SIGA2 Testifire Adapter Assembly
Installation Sheet(P/N 3101942) for further details.
To perform an initial installation test:
1. Visually inspect each detector and verify that it is installed
in the correct location. Make sure it is not adversely
affected by factors not apparent on the plans.
2. Remove the detector from its base and verify that the
proper detector address, trouble signals, and messages
are reported.
3. If wired for Class A operation, verify that the detector
continues to operate first with the SLC_IN disconnected,
and then with the SLC_OUT disconnected. (Refer to the
installation sheet for the base.)
4. Place a momentary ground fault on the SLC circuit to
verify operation of the ground fault detection circuitry.
5. Perform a sensor function test, as described below.
To perform a function test:
1. If desired, use the fire alarm control panel to put the
detector or zone into a service group for testing. (Refer to
the panel technical reference manual for instructions.)
2. Activate the heat sensor using a hair dryer (maintaining a
distance of three inches) or using a Testifire detector
tester per the manufacturer’s instructions.
Maintenance
To ensure proper operation, plan maintenance in accordance
with the requirements of the authority having jurisdiction. Refer
to CAN/ULC-S536 Standard for the Inspection and Testing of
Fire Alarm Systems and NFPA 72 National Fire Alarm and
Signaling Code.
Refer to Technical Bulletin P/N 270145 REV 4.0 or later for
additional information and cleaning instructions.
