Learn Mode Rate of Rise Heat Sensors

Installation Instructions

Introduction

This is the Learn Mode Rate-of-Rise Heat Sensors

Installation Instructions. The sensors (Figure 1) combine a

Chemetron heat detector and a learn mode wireless

transmitter in one unit. A built-in thermostat trips the transmitter

when the temperature at the sensor location reaches about

135°F (57°C) or 200°F (94°C), depending on the model

installed.

135°F models

60-460-95/NX-495, 60-460-95-LB

200°F models

60-460-01-95/NX-496

Since many fires grow rapidly in intensity causing a rapid

temperature increase, the thermostat also trips the transmitter

if the temperature rises 15°F (8°C) or more per minute.

All models can be powered by one 9-volt alkaline battery that

can last 12 to 18 months, or by one 9-volt lithium battery that

can last up to twice as long.

Note: Battery life depends on how often the sensor transmits

signals, but is more dependent on the temperature of the

installation environment. Alkaline batteries self-discharge more

rapidly when used in high temperature environments.

When the battery voltage gets low, the sensor transmits a low

battery signal to the panel. The panel then activates sirens with

trouble beeps to notify the customer that the sensor battery

must be replaced

Caution: SX-V Special panels must have software version 8.0

or later installed for correct response from the sensors. Do not

install Learn Mode Rate of Rise Heat sensors if the panel an

earlier software version. Contact Interlogix technical support at

888.437.3287 for assistance.

Installation

Use the following installation guidelines:

• Heat sensors should be installed to provide property

protection. Reliance should not be placed on heat

detectors for life safety. Where life safety is involved,

smoke sensors must also be installed.

• The sensors allow for normal temperature fluctuations,

however, ceiling temperatures should not exceed 100°F

(37°C) when installing 135°F models, or 150°F (66°C)

when installing 200°F models.

• Mount the sensor in a central location of the area to be

protected, either on the ceiling or on a wall.

• If mounting on a ceiling, the sensor must be at least 4 in.

(10 cm) away from any walls.

• If mounting on a wall, the top of the sensor must be within

4 to 6 in. (10 to 15 cm) of the ceiling.

• The UL maximum spacing allowance of the sensor is 50 x

50 ft. (15 x 15 m). Refer to the NFPA Standard 72 for

application requirements.

• Do not mount the sensor close to devices that change temperature rapidly, such as ovens, heat vents, furnaces, or boilers. Testing Before permanently securing the sensor to the wall or ceiling, test the sensor from the installation location using one of the following methods.
