9825 Keypad Addressing

Before connecting the keypad(s) to the system, the engineer must set the

address of each keypad. Each keypad in a system must have a different

address number to ensure that the control unit can correctly identify them.

To set the address:

1. Ensure the system is powered down.

2. Open the keypad and identify the four position DIP switch on the keypad

pcb, see Figure 1 below. Note that each switch is numbered 1 to 4. The

numbers correspond to the keypad address.

3. Select one switch and move it to the ON position (up). Make sure all the

other switches are OFF (down). The keypad now has the address given

by the switch that is ON.

Adjusting Keypad Sounder Volume

You can alter the volume of the keypad sounder by adjusting the potentio-

meter located next to the sounder. See Figure 1. When first installing the

keypad set the potentiometer midway using a small screwdriver.
