installed in compliance with the National Fire Protection Association (NFPA);
see NFPA 72.
GENERAL DESCRIPTION
Models HFS-P and HFS-PT are plug-in type smoke sensors with a plug-in detector base that combine a photoelectronic sensing chamber with addressable-analog communications. The sensors transmit 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. The detector is
intended for use in a 2-wire intelligent system, with screw terminals provided
for power (+ and –).
Two LEDs on the sensor are controlled by the panel to indicate sensor status. Model HFS-PT combines a photoelectronic sensing chamber and 135°F
(57.2°C) fixed temperature heat detector.
The HFS-P and HFS-PT require compatible addressable communications to function properly. Connect these sensors to listed-compatible control panels only.
Communication takes place over the power (+ and –) lines.

SPACING
Space sensors in compliance with NFPA 72. In low air flow applications with
smooth ceilings, space sensors 30 feet apart. For specific information regarding sensor spacing, placement, and special applications, refer to NFPA 72 or
the System Smoke Detector Application Guide.
NOTE: These products are not listed for use inside duct smoke detectors.
MOUNTING
This detector base mounts directly to 3½- and 4-inch octagon boxes, 4-inch
square boxes (with or without plaster rings, see Figure 2), and single gang
boxes. Install the base on the box using the screws supplied with the junction
box and the appropriate mounting slots in the base.
WIRING GUIDE
All wiring must be installed in compliance with the National Electrical Code,
applicable local codes, and any special requirements of the Authority Having Jurisdiction. Proper wire gauges should be used. The conductors used to
connect smoke detectors to control panels and accessory devices should be
color-coded to reduce the likelihood of wiring errors. Improper connections
will prevent a system from responding properly in the event of a fire.
For signal wiring (the wiring between interconnected detectors), it is recommended that the wire be no smaller than AWG 18. However, the screws and
clamping plate in the base can accommodate wire sizes up to AWG 12. The
use of twisted pair wiring or shielded cable for the power (+ and –) loop is
recommended to minimize the effects of electrical interference.

be continuous by using wire nuts, crimping, or soldering, as appropriate for a
reliable connection.
Make electrical connections by stripping about 3/8 inch (10 mm) of insulation
from the end of the wire (use strip gauge molded in base), sliding the bare end
of the wire under the clamping plate, and tightening the clamping plate screw.
Do not loop the wire under the clamping plate.
The zone wiring of the detector base should be checked before the detector
heads are installed in them. The wiring should be checked for continuity and
polarity in the base, and dielectric tests should be performed.
The base includes a label for recording the zone, address, and type of detector
being installed. This information is important to set the address of the detector
head that will later be plugged into the base and to verify the type required
for that location.
Remove power from the communication line before installing sensors.
1. Wire the sensor base per the wiring diagram, Figure 3.
2. Reference the control panel device address map to determine appropriate
addressing.
3. Set the desired address on the sensor address switches, see Figure 4.
4. Install the sensor into the sensor base. Push the sensor into the base
while turning it clockwise to secure it in place.
5. After all sensors have been installed, apply power to the control unit and
activate the communication line.
6. Test the sensor(s) as described in the TESTING section of this manual.
TAMPER-RESISTANCE
The Tamper Resistant Tab, in the Detector Mounting Base, can make the detector tamper-resistant by making it necessary to use a small screwdriver or
similar tool to detach the detector from the base.
To make the detector tamper-resistant, use needle-nose pliers to break the
smaller tab at the scribed line on the tamper resistant tab. Figures 5 and 6
show the location of this tab on the detector mounting bracket.
To remove the detector from the base after it has been made tamper resistant,
insert a small screwdriver into the notch, as indicated in Figure 1, and press
the plastic lever toward the mounting surface before rotating the detector
counterclockwise for removal.

Dust covers provide limited protection against airborne dust particles during shipping. Dust covers must be removed before the sensors can sense smoke. Remove
sensors prior to heavy remodeling or construction.

Before testing, notify the proper authorities that the system is undergoing
maintenance, and will temporarily be out of service. Disable the system to
prevent unwanted alarms.
All sensors must be tested after installation and periodically thereafter. Testing methods must satisfy the Authority Having Jurisdiction (AHJ). Sensors
offer maximum performance when tested and maintained in compliance with
NFPA 72.
The sensor can be tested in the following ways:
A. Functional: Magnet Test (P/N M02-04-01 or M02-09-00)
This sensor can be functionally tested with a test magnet. The test mag-
net electronically simulates smoke in the sensing chamber, testing the
sensor electronics and connections to the control panel.
1. Hold the test magnet in the magnet test area as shown in Figure 6.
2. The sensor should alarm the panel.
Two LEDs on the sensor are controlled by the panel to indicate sensor
status. Coded signals, transmitted from the panel, can cause the LEDs
to blink, latch on, or latch off. Refer to the control panel technical documentation for sensor LED status operation and expected delay to alarm.
B. Smoke Entry
The GEMINI model 501 aerosol generator can be used for smoke entry
testing. Set the generator to represent 4%/ft to 5%/ft obscuration as described in the GEMINI 501 manual. Using the bowl shaped applicator,
apply aerosol until the panel alarms.
Additionally, canned aerosol simulated smoke (canned smoke agent)
may be used for smoke entry testing of the smoke detector. Tested and
approved aerosol smoke products are:

When used properly, the canned smoke agent will cause the smoke detector
CAUTION
to go into alarm. Refer to the manufacturer’s published instructions for proper
use of the canned smoke agent.
Canned aerosol simulated smoke (canned smoke agent) formulas will vary by
manufacturer. Misuse or overuse of these products may have long term adverse effects on the smoke detector. Consult the canned smoke agent manufacturer’s published instructions for any further warnings or caution statements.
C. Direct Heat Method (Hair dryer of 1000-1500 watts). HFS-PT only.
A hair dryer of 1000-1500 watts should be used to test the thermistors. Di-
rect the heat toward either of the two thermistors, holding the heat source
approximately 12 inches from the detector in order to avoid damaging
the plastic housing. The detector will reset only after it has had sufficient
time to cool. Make sure both thermistors are tested individually.
A sensor that fails any of these tests should be cleaned as described under
CLEANING, and retested. If the sensor fails after cleaning, it must be replaced
and returned for repair.
When testing is complete, restore the system to normal operation and notify
the proper authorities that the system is back in operation.
CLEANING: (SEE FIGURE 7)
Before removing the detector, notify the proper authorities that the smoke detector system is undergoing maintenance and will be temporarily out of service.
Disable the zone or system undergoing maintenance to prevent unwanted alarms.
1. Remove the sensor to be cleaned from the system.
2. Remove the sensor cover by pressing firmly on each of the four removal
tabs that hold the cover in place.
3. Vacuum the screen carefully without removing it. If further cleaning is
required continue with Step 4, otherwise skip to Step 7.
4. Remove the chamber cover/screen assembly by pulling it straight out.
5. Use a vacuum cleaner or compressed air to remove dust and debris from
the sensing chamber.
6. Reinstall the chamber cover/screen assembly by sliding the edge over the
sensing chamber. Turn until it is firmly in place.
7. Replace the cover using the LEDs to align the cover and then gently
pushing it until it locks into place. Make sure that the thermistors do not
become bent under the cover on the HFS-PT models.
8. Reinstall the detector.
9. Test the detector as described in TESTING.
10. Reconnect disabled circuits.
11. Notify the proper authorities that the system is back on line.
SPECIAL NOTE REGARDING SMOKE DETECTOR GUARDS
Smoke detectors are not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose.
