2. Remove the divider separating the battery from the contacts on the battery

holder. When you apply power and the Tamper switch is open, the DS831

enters Test mode during which a transmission is sent every few seconds. You

can terminate Test mode by closing the Tamper switch.

Note: Due to the occurrence of voltage delay in lithium batteries that

have been in storage, the batteries may initially appear to be dead. In

this case, leave the unit in Test mode for a few minutes until the battery

voltage level is stabilized.

When handling the PCB, do not apply pressure on the antenna.

3. From the Programming menu, select Devices, Zones [911].

4. Select the zone to which you

want to register the

transmitter; the system

initiates Registration mode.

When Save? appears on the

panel’s LCD display, press 9.

5. After registration, press the DS831’s tamper switch to terminate Test mode.

6. Before permanently mounting the unit, test the transmitter from the

exact mounting position.

7. To remove the PCB, press the PCB release tab and carefully

lift the board and slide the board away from the back cover.

8. The DS831 is able to operate in three modes: Magnetic

Switch, Universal Transmitter or a combination of the two. If

connecting a wired contact loop (N.C.), connect the terminal

block as follows: 1 - Alarm; 2 - GND. For this purpose, a wiring

knockout is provided in the back cover.

9. Mount the back cover using two screws and replace the

PCB. Use ISO 7050 (ST3.5 x 22) or similar countersunk

screws so that the screw head will not touch the PCB – see

Figure B.4.

10. To open the magnet’s housing, insert a small screwdriver into one of the pry-

off slots located at either end of the magnet’s back cover and lift to separate

from the front cover.

11. Mount the back cover of the magnet using two screws. Make sure that the

guideline on the magnet is correctly aligned with the guideline on the

transmitter.

Do not install the magnet further than 1cm from the transmitter.

12. Test the transmitter, making certain that the LED is lit when opening the

door/window and again when closing.

13. Close the front covers of the transmitter and the magnet.
