Conventional Heat Detector

GENERAL DESCRIPTION

Model WT105 is intelligent sensors that utilize a

state-of-the-art thermistor sensing circuit for fast

response. These sensors are designed to provide open

area protection with 50 foot spacing capability. Model

WT105 is a rate-of-rise temperature sensor with 135°F

fixed temperature alarm.

Model WT105 is a rate-of-rise with fixed temperature

alarm thermal detector utilizing a state-of-the-art dual

thermistor sensing circuit. These detectors are

designed to provide open area protection with 50-foot

spacing capability, and are to be used with compatible

control panels only.

Two LEDs on each detector light to provide 360°

visibility of the detector indication.

INSTALLATION

BEFORE INSTALLING

This detector must be installed in compliance with the

control panel installation manual and meet the

requirements of the authority having jurisdiction. In

addition, the National Fire Protection Association has

published codes, standards, and recommended

practices for the installation and use of detectors,

NFPA 72.

Therefore, the installer must be familiar with these

requirements, with local codes, and any special

requirements of the authority having jurisdiction..

NOTICE: This manual should be left with the

owner/user of this equipment.

IMPORTANT: The detector must be tested and

maintained regularly following NFPA 72 requirements.

The detector should be cleaned at least once a year.


INSTALLATION

NOTE: All wiring must conform to applicable local

codes, ordinances, and regulations.

NOTE: Verify that all detector bases are installed, that

the initiating-device circuits have been tested, and that the

wiring is correct.

Remove power from initiating-device circuits before

installing detectors.

1. Wire the sensor base per the wiring diagram, Figure 1.

2. Install the sensor into the sensor base. Push the sensor

into the base while turning it clockwise to secure it in

place.

3. After all sensors have been installed, apply power to

the control unit.

4. Test the sensor(s) as described in the TESTING section

of this manual.

5. Notify the proper authorities that the system is in

operation.
