Product Information Product Information The AXC-TEMP Temperature Control card (FIG. 1) provides control and power for the RTS1 Room Temperature Sensor (FIG. 2). The RTS1 provides precision temperature sensing for the AXT-TEMP. FIG. 1 AXC-TEMP FIG. 2 RTS1 Features The AXC-TEMP features include: ! Standard Axcess CardFrame slot size ! Settings for Fahrenheit or Celsius operation ! Control and power for up to four independent RTS1 units ! Measurement accuracy of +/- 2°F (+/- 1.

Specifications AXC-TEMP Input voltage +12 to 18 VDC Current Draw 40 mA (using four RTS1s = 75 mA) Temperature range 0.0 ° F to +250 ° F (0.0 ° C to +106.9 ° C) Accuracy +/-2 ° F (+/-1.1 ° C) Resolution 10-bit (1024 steps over range) RTS1 2 Weight 3.2 oz. (91 grams) Dimensions 4.5" x 2.
Pre-Installation Pre-Installation Before installing the AXT-TEMP and RTS1, you must properly set jumpers and potentiometers (POTs). Setting Fahrenheit or Celsius Set the Fahrenheit or Celsius feature by manually selecting each jumper (JP1- JP4) or by manually selecting the RAW A/D OUTPUT jumper on the card. FIG. 3 shows the location of the jumpers and POTs. The RAW A/D OUTPUT jumper overrides jumpers JP1 - JP4. Jumpers JP5 - JP8 Channels 1 - 4 Jumpers JP1 - JP4 and JP13 (RAW) Jumpers JP9 - JP12 FIG.
Pre-Installation 4. Hold the card by the tab end and slide the card into the frame. Make sure the card is correctly positioned in the guide slot. 5. Gently push the card in until it is firmly seated in the card connector slot. It is not necessary to disconnect the power to the CardFrame when installing the card. Calibrating POTs Use the four calibration potentiometers (POTs), marked CH 1 - CH 4, to adjust the respective RTS1 units 1 - 4. The default setting for each POT pointer is 0°.
Pre-Installation RTS1 Preparation To install the RTS1 units: 1. Wire RTS1 units 1 - 4. Refer to Wiring the RTS1 for additional information. 2. Check the temperature. ! If the panel has a display, check the temperature readings on the system Wiring control panel. The temperature readings will change when the room temperature changes by a half degree. ! If the panel does not have a display, check the variables in Axcess. Wiring the RTS1 Use Belden 8723 or equivalent cable.

Pre-Installation Testing the RTS1 Touch the sensor at the bottom each RTS1 unit for a few seconds. The temperature on the display panel should change. If the temperature does not change: 1. Check the wiring to each RTS1 unit that did not display a temperature change. 2. Verify the AXC-TEMP card is properly seated in the CardFrame. Repeat the steps provided in the RTS1 Calibration section on page 6, if required.

Programming Programming This section provides the Axcess programming commands for the AXC-TEMP and RTS1. ! The TEMP_LEVEL variable receives data from the TEMP card (Device 16), inputs 1 - 4. ! The data is in three-digit numbers (986 = 98.6 degrees). The SEND_STRING command to the Mini-LCD Panel converts the number to print with a decimal point. ! The 12 clears the LCD screen.
