SIGA-HFD Intelligent Fixed-
Temperature Heat Detector
Installation Sheet
Description
The Signature Series SIGA-HFD Intelligent Fixed-Temperature Heat
Detector that contains a fixed-temperature heat sensor to detect heat
from fire. The heat sensor monitors the temperature of the air in its
surroundings and the detector analyzes the data to determine whether
to initiate an alarm.

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-TSTSPACER Testifire Adapter Assembly
Installation Sheet (P/N 3101942-ML) for further details.

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 detector by itself does not provide smoke or fire 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, visible 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 Part 1, and the local authority having jurisdiction.
