V-HFD Fixed-Temperature Heat Detector
Installation Sheet
EN FR
EN: Installation Sheet
Operation
The V-HFD Fixed-Temperature Heat Detector is an intelligent
analog device that contains a 135°F (57°C) fixed-temperature
heat sensor to detect heat from fire. The heat sensor monitors
the temperature of the air in its surroundings and determines
whether to initiate an alarm. The detector is capable of
performing comprehensive self-diagnostics and storing the
results.
LED operation
The detector provides a bicolor LED that shows its status.
Normal: Green LED flashes
Alarm/active: Red LED flashes
Electronic addressing
The control panel automatically assigns addresses to the
detectors. Use a laptop computer to address custom
addresses to the detectors. No addressing switches are used.
Installation
Refer to
Smoke and Heat Detector Application Bulletin
(P/N 3101109) for additional information on detector placement
and spacing.
WARNINGS
•
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 smoke
cannot reach the detector. Smoke from fires in walls,
roofs, or on the opposite side of closed doors may not
reach the detector.
•
This detector is intended for use with ionization and/or
photoelectric smoke detectors. The heat detector by itself
does not provide life safety protection.
•
This detector does not detect oxygen levels, smoke, toxic
gases, or flames. Use this device only 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 recommend using heat detectors only
for property protection. Never rely on heat detectors as the
sole means of fire protection.
•
To ensure proper operation, schedule maintenance
(regular or selected) in accordance with the requirements
of the authority having jurisdiction. Refer to NFPA 72 and
CAN/ULC−S536.
•
To ensure proper operation, store the detector within the
recommended ranges. Allow the detector to stabilize to
room temperature before applying power.
•
Keep the dust cover (supplied) on the detector during
installation and remove it prior to commissioning and
service. The dust cover is not a substitute for removing the
detector during new construction or heavy remodeling.
To install the detector:
1. Install and wire the detector base using the installation
sheet supplied with the detector base.
2. Connect the detector to the base by rotating the detector
clockwise until it snaps into the locked position.
The head can be removed by turning it counterclockwise.
3. If the head must lock to the base, break away the locking
tab using a pair of pliers. See Figure 1.
To then remove the detector head after breaking away the
locking tab, insert a small screwdriver into the slot on the
side of the base and press in while simultaneously turning
the detector head counterclockwise.
4. Log the serial number on the appropriate worksheet.
