6 | Audible tones
The keypad has a built-in speaker that produces several distinct
warning tones. The keypad backlight illuminates when it emits
an audible tone.
Tone Description
Fire alarm When an area is in fire alarm, the keypad
emits a pulsed, high-pitched bell tone.
Gas alarm When a gas point activates, the keypad
emits a unique high pitched tone.
User alarm When a user alarm (such as panic and
medical alarms) occurs, the tone sounds
for the programmed amount of time.
Burglary alarm When an area is in alarm, the keypad
emits a steady, high pitched bell tone.
Entry delay The keypad emits an intermittent beep
tone during entry delay periods to remind
the user to disarm the area.
Exit delay The keypad emits an intermittent beep
tone during exit delay.
Invalid button When an invalid button, or sequence of
buzz buttons, is pressed, the keypad emits a
flat buzz tone.
Keypress The keypad emits a muted beep tone as
each button is pressed to indicate that
the entry was accepted.
Trouble When a trouble event occurs, such as a
service alert, the keypad emits a two-tone
warble until you enter a programmed
passcode with the appropriate authority.
Watch point A single clean tweedle tone alerts the
fault user anytime a watch point is faulted.

7 | Supervision
The control panel supervises all keypads on the SDI2 bus.
If a supervised keypad fails to respond to the control panel,
the control panel declares a Missing Keypad Trouble. When
the control panel can again communicate with the keypad,
it restores the Missing Keypad Trouble. During a Missing
Keypad Trouble, any connected keypad that maintained
contact with the control panel shows the Missing Keypad
Trouble as its idle text, and shows the missing keypad's
address. The communicating keypads also sound a trouble
tone. Users can silence the trouble tone. If no other troubles
exist, the tone silences when the missing keypad restores.
8 | Show the firmware version
Showing the keypad firmware version:
1. Remove the keypad from the base to remove power to the
keypad. Refer to Figures 2.1 and 2.2.
2. Return the keypad to the base to restore power.
The keypad shows the model number, keypad address, and
firmware version for 10 seconds.
NOTICE!
You can also view a keypad's firmware version in RPS.
9 | Cleaning the keypad
Use a soft cloth and non-abrasive cleaning solution to clean your
keypad (for example, microfiber cloth and eyeglass cleaner).
Spray the cleaner onto the cloth. Do not spray cleaners directly
onto the keypad.
