HDX-135-345 Wireless Rate-of-Rise Heat Sensor Installation Instructions

Introduction

The Interlogix HDX series wireless heat detectors use
electronic processing to detect temperature Rate-of-Rise
and fixed heat set point conditions plus a learn mode
wireless transmitter in one unit. The micro-processor trips
the transmitter when the temperature at the detector location
reaches a fixed temperature of 135°F (57°C) or senses a
rate of rise at 12°F to 15ºF (6.7 to 8.3ºC)

Sensor, 345 MHz Wireless, Compatible with
Honeywell and 2GIG Wireless Receivers

Installation

Use the following installation guidelines:

• Heat detectors should be installed to provide property
protection. Reliance should not be placed on heat
sensors for life safety. Where life safety is involved,
smoke sensors must also be installed.

• The detectors allow for normal temperature fluctuations,
however, ceiling temperatures should not exceed 100°F
(38°C)

• Mount the detector in a central location of the area to be
protected, either on the ceiling or on a wall.

• If mounting on a ceiling, the detect or must be at least 4
in. (10 cm) away from any walls.

• If mounting on a wall, the top of the detector must be
within 4 to 6 in. (10 to 15 cm) of the ceiling.

• The UL maximum spacing allowance of the detector is
50 x 50 ft. (15 x 15 m). Refer to the NFPA Standard 72
for application requirements.

• Do not mount the detector close to devices that change
temperature rapidly, such as ovens, heat vents,
furnaces, or boilers.

Enrolling

The HDX-135-345 is compatible with Honeywell and 2GIG
wireless receivers. These panels must learn (program) the
detector ID codes in order to respond to detector signals. For
complete programming instructions refer to the specific

control panel instruction guides.
To add the sensor to panel memory:

Honeywell™

The HDX-135-345 must be enrolled in the control panel
before it can operate in the system . The heat protect ion zone
must be enrolled as Loop 1 and “Input Type” 3 (supervised
RF). Tamper is transmitted as Loop 4, but does not require
programming.

1. Place the panel in program mode.

2. Enter the zone number to be programmed.

3. Enter the zone type when prompted. Program as a Fire
zone type [9]

4. When prompted, enter Input Type [03] (3 on some

panels) – Supervised RF Transmitter

5. Remove pull tab from sensor battery

6. When prompted for the serial number, transmit from the
detector by activating (press and release) the tamper
switch (Figure 2).

7. When serial number is displayed, transmit from sensor
again by activating tamper switch again. The current
loop number will begin to flash (4).

8. Manually change the loop number to loop number [1].

Note: The fire protection zone enrolled must always be
Loop 1. Otherwise, fire annunciations will not be
reported by the control

9. Exit programming when complete. Test the sensor after
enrolling into the system. Refer to the Testing section in
this guide.

The following procedure describes how to learn-in the HDX­135-345 heat sensor into the 2GIG control panel.

1. Select RF sensor #(01 to 48)

2. Select RF sensor type [09] Smoke/Heat

3. Select RF sensor equipment code. Enter code 0895

cause a tamper by pressing and then release tamper
switch (Figure 2). The correct TX ID should appear.
Accept by pressing OK.

5. Select RF sensor equipment age [0] New

6. Select RF sensor loop number [1]

7. Select dialer delay (enable/disable)

8. Select voice descriptors (see panel manual)

9. Select sensor reports (enable/disable)

10. Select sensor chime

11. To exit programming, click skip

12. Click end and exit. The panel takes a few seconds to
reset.

Mounting the Detector

1. Locate the base mounting holes and mount the base to
the wall or ceiling with the appropriate hardware (Figure

3)

2. Attach the detector to the mounting bas e

Figure 4: Magnet Mark

1. With the sensor permanently mounted, place a magnet
against the mark located on the sensor body. (Figure 4)

2. Hold the magnet in place for about 15 seconds

3. The control panel should respond by sounding the fire
alarm

4. Disarm control panel to silence alarm

Replacing the Batteries

Battery life depends on how often the detector transmits
signals, but is more dependent on the temperature of the
installation environment. When the battery voltage gets low,
the detector transmits a low battery signal to the panel. The
panel then activates trouble beeps to notify the customer
that the detector battery must be replaced. Pressing the
status button identifies the sensor with the low battery.

Testing

1. Before permanently securing the detector to the wall or
ceiling, test the detector from the installation location
using one of the following methods.

2. Place the panel in sensor test mode.

3. Plug in a portable hair dryer.

4. Hold the hair dryer about 12 to 18 in. away from the
sensor, aiming it at the side of the sensor.

5. Listen for the appropriate number of beeps from interior
sirens and speakers (refer to the specific panel

6. Listen for the appropriate number of beeps from interior
sirens and speakers

Magnet Test

Note: Notify central station before any live testing to avoid fire
response. The magnet test allows the sensor to send an actual
alarm signal to the control panel, if a magnet is held against the
housing for 15 seconds.

Replace the battery immediately when this condition occurs,
using the following battery: Panasonic CR123A 3V

Battery Disposal

The batteries used in this sensor are lithium batteries and
are not reusable. Be sure to properly dispose of used lithium
batteries according to your local hazardous waste disposal
laws.
