NOTICE!
Use the strip gauge on the plate to reduce wires to 7 mm.
Attach one wire per terminal.
1. Put the keypad on a smooth surface.
2. Use a ballpoint pen to press the button on the terminal release.
3. Put the wire into the terminal. When you remove the pen, the
terminal release locks the wire.
4. To remove wires, press the terminal release.
5. Gently pull the wire out.
3.1 | Attach to the control panel
Use the control panel terminals labeled R, Y, G, B (PWR, A, B, COM).
Connect them to the keypad terminals labeled R, Y, G, B.
You can connect keypads to the SDI2 data bus by parallel wire run from
the control panel to each keypad, wire from keypad to keypad, or a
combination of the two techniques. Refer to the following illustrations
in this section.

3.2 | Attach the inputs
Wire resistance on each sensor input must be less than
100 Ω with the detection devices connected. The terminal block
supports 18 to 22 AWG (1.02 to 0.65 mm) wires.
The keypad identifies open, short, normal, and ground fault circuit
conditions on its sensor loops and transmits the conditions to the
control panel. Each sensor loop has a point number and transmits to
the control panel individually. Run wires away from any telephone
and AC wiring.

3.3 | Attach the output
The keypad provides one NO (normally open) output. It includes NO
and C (COMMON) terminals. When the output is active (energized),
the NO has continuity with the C terminal.
NOTICE!
Do not exceed relay contact ratings of 1.0 A, 24 VDC,
resistive load.
3.4 | Install the keypad
1. Align the mounting hook opennings over the hooks.
2. Push the keypad down.
4 | Set the address
Each SDI2 keypad must have a unique address. For single-digit
addresses 1 through 9, set the tens switch to 0. The following
illustration shows the address switch setting for address 1.
NOTICE!
Only use your finger or a touch screen stylus on the
keypad.
1. To show the start up screen, apply power to the keypad or push
Time/Date for 5 seconds. You can also push anywhere on Call for
Service screen.
2. Hold the countdown icon for 5 seconds to show the addressing page.
3. Use the up and down arrows to change the ones and tens digits.
4. Push (Escape) to save the setting and return to the power up
