Before Installing
This detector must be installed in compliance with the
control panel system installation manual. The installation
must meet the requirements of the Authority Having Juris-
diction (AHJ). Detectors offer maximum performance when
installed in compliance with the National Fire Protection
Association (NFPA); see NFPA 72.
General Description
The HPX-751 Smoke Detector uses a small air intake fan
and a high density replaceable filter. Air and smoke are
drawn into a photoelectric sensing chamber while airborne
particulate and water mist are removed. The addressable-
analog detector transmits an analog representation of
smoke density over a communication line to a control
panel. Rotary decade switches are provided for setting the
sensor’s address. Two LEDs on the sensor are controlled
by the panel to indicate sensor status.
The HPX-751 smoke detector is intended for use in
normal environmental conditions, where dust and oth-
er airborne particulate are present at elevated levels.
These elevated levels tend to cause false alarms and
high maintenance in standard detectors. HPX-751 pro-
vides a protective enclosure for a photoelectric smoke
detector chamber and allows smoke detection in areas
that tended to use exclusively heat detection.
HPX-751 requires compatible addressable communic-
ations to function properly. Connect this detector to
listed-compatible control panels
only.
Spacing
Notifier recommends spacing detectors in compliance with
NFPA 72. In low air flow applications with smooth ceilings,
space detectors 30 feet apart. For specific information
regarding sensor spacing, placement, and special appli-
cations, refer to NFPA 72 or the
System Smoke Detector

Figure 5: Installing detector into base:
1. Grasp the housing with one hand and the cover with
the other. Turn the cover counterclockwise fully (approx.
30 degrees) and remove cover by pulling it away from
detector unit (see Figure 4).
2. Replace with new filter and cover assembly.
The cover
is keyed so it fits in place only one way. Turn the cover
clockwise until it stops.
NOTE:
The base is equipped with an optional tamperproof
feature which can be used to prevent unintentional removal
of the unit while replacing the filter.
If a clogged filter was the cause of the trouble condition,
normal detector operation should resume automatically
within five minutes. If the trouble condition persists, the
detector must be returned for repair or replacement.
Installing Detector Into Base
1. Align the detector at a right angle to the base, with the
five wires and connectors adjacent to the connector re-
ceptacle as shown in Figure 5.
2. Plug the wired connector into the receptacle.
3. Rotate the detector into the base, making sure detector
and base keyed fit is lined up. Turn the detector clock-
wise until it snaps into place.
IMPORTANT: HPX-751 will only operate with B710HD/
B524FTXE Mounting Base.
FCC Statement
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful inter-
ference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These lim-
its are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interferenc
nications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful int
ference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the inter-
ference by one or more of the following measures:
– Reorient or relocate the receiving antenna.
– Increase the separation between the equipment and receiver.
– Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
– Consult the dealer or an experienced radio/TV technician for help.
