AT&T Model SW-ATT-TF, Temperature/Flood Sensor

Description

The AT&T model number SW-ATT-TF Sensor is a fully supervised, tamper

protected sensor that will monitor ambient temperature detect a flood/no flood

condition. It reports these conditions to the Digital Life Controller. The sensor

can be configured to detect temperature only

Flood Conditions—once the sensor detects the presence of water, the integral

transmitter will send a flood alarm transmission to the Digital Life Controller.

The sensor will also send a restore (no flood) report when the presence of

water is no longer detected by the flood sensor. For flood reporting the sensor

requires the installation of the supplied external flood probe.

Temperature Conditions—the temperature sensor will check the ambient

temperature approximately once per minute. If the temperature has changed

by three (3) degrees F or more since the sensor’s last 3 degree report, the

integral transmitter will send a temperature report to the Digital Life Controller.

(Check the installation section for required wiring for the sensor if it is used in

temperature only configuration.) The temperature sensor does not send a

restore message, but does send ambient temperature approximately once

every 70 minutes as part of the supervisory transmission.

Low Battery—if the battery voltage falls below a prescribed voltage level, the

integral transmitter will a low battery report to the Digital Life Controller

whenever transmitting. (See the ―Changing the Battery‖ section of these

instructions for information about changing the battery.)

Flood Probe Fault- if at any time the sensor detects that the wiring between

the sensor and the flood probe is either open circuit (wire cut or missing) or

short circuit (e.g. installation staple cutting into wires), the sensor will transmit

―sensor trouble‖ multiple times or until the fault is corrected.

Installing the Battery

When the system indicates the sensor battery is low, replace it immediately.

Use the recommended replacement batteries (See specification) or contact

AT&T technical support for more information.

To install the battery, do the following: 1. Carefully remove the top cover from the base by pressing on the end release button (see Figure 1) and then remove the cover. 2. Remove the depleted battery and dispose of the battery as required by local laws. (Disregard this step for new system installation.) 3. Insert the replacement battery with the + sign facing towards the middle of the sensor. (The side with the spring is the – side of the battery.) 4. Replace the top cover. 5.

For Temperature Only Operation 1. Install the supplied 2.2 Megaohm resistor between the Flood Probe screw terminals on the sensor circuit board. (See Figure 3) 2. The sensor is configured for Temperature only operation. FIGURE 3 For Temperature/Flood Operation The flood probe is supplied with a four-foot wire. Connect the flood probe to the screw terminals located on the sensor circuit board. Observe the polarity of the wires shown in Figure 4.

WHITE WIRE BLACK WIRE For Flood Only Operation The sensor is designed to automatically detect the ambient temperature of the area where it is located. For flood only applications, the Digital Life Controller will require programming to ignore the temperature reports. The flood probe is supplied with a four-foot wire lead. Connect the flood probe wires to the screw terminals located on the sensor circuit board. Observe polarity, Black wire connects to the terminal next to the tamper switch.

(Per AT&T requirements) Verifying the programming and RF communications (Per AT&T requirements) Case Tamper Detection Removing the cover of the SW-ATT-TF will cause the integral transmitter to send a case tamper report to the Digital Life Controller. This tamper condition will remain on the system until the case cover is reinstalled and the integral transmitter sends a tamper restore to the Digital Life Controller.
