TX-3AS Analog/Temperature Two-in-One Sensor

INTRODUCTION

The TX-3AS is a battery operated wireless Analog/Temperature sensor specially

designed for the LS-30 Security System. Any Analog external sensor with 0-20mA

(or 0-2V*) output can be connected to the terminals and TX-3AS will translate it

into 0-200 readings and transmit the result to the Base Unit by RF signal.

With built-in temperature sensor and wireless operation, the sensor can be put

anywhere to monitor/record the data from an Analog external sensor and the

temperature in a room, a chamber or even a freezer and the reading will be remotely

shown/store in the Base Unit.

(* 0-2V actually is 0-1.952V, please refer to the Specifications.)

INSTALLATION A. Enrolling Code 1. Loosen the screw of the TX-3AS, open the upper case and connect the Analog external sensor output to the terminals (make sure the output of the Analog external sensor is in the operation range of 0-20mA or 0-2V, if the output is over this range please see the Appendix to adjust the output level before connecting to the terminals). Insert two AAA alkaline batteries then put back the cover..

B. Mounting It is recommended to attach the sensor on a flat surface by the Velcro supplied. Note: Do not mount the sensor on a metal surface, the RF transmission range will be shrunk due to radio signal attenuation. If the sensor is put in a closed freezer, there maybe a large reduction in radio range. The user should move the Base Unit closer to the sensor or using a repeater to relay the RF signal. C.

Control Device: The reading from this device will not issue any alarm but control the operation of the switches those have been assigned by this device. High Limit Operation: Turn on at high limit reading and turn off at low limit reading. Low Limit Operation: Turn on at low limit reading and turn off at high limit reading.
