1.0 Description

The D720 Series is compatible with the following control panels:

The D720 Series Keypads (D720, D720W, and D720B) are low profile surface mount, four–wire units which can annunciate up to eight protective points on its LED display. They have a [COMMAND] bar, an [ENT] (ENTER) key, and number keys from [0] to [9]. The keys are used to enter personal passcodes and command functions. When a key is pressed, the keypad is backlit and the keypad emits a short beep to indicate that the buffer has stored the entry.

When a passcode is completed, the [ENT] key must be pressed to enter the passcode. If the [ENT] key is not pressed, the passcode is ignored by the control panel. The [ENT] key is not required to enter [COMMAND] bar functions.

The keypad has a time window for accepting key entries. After one key is pressed, the next key in the passcode must be pressed within five seconds. After five seconds have expired from the last key entry, the entire entry is cleared and the passcode must be restarted.

2.0 Function Keys

The D720 Series Keypad has three programmable function keys labeled [A], [B], and [C]. Each key can be programmed to perform many command functions of the control panel. This enables the user to press one button to perform command functions instead of memorizing the command combination. For complete details concerning the programming of the function keys, refer to Section 7.3 Custom Functions on page 6.

3.0 Response Tones

The keypad contains a sounder used to annunciate several system conditions and area conditions. The response tones are as follows:

Table 2: D720 Series Response tones

Tone Description

Entry/Exit Delay The keypad beeps during the entry/exit delay period to remind the user to disarm the security system. This

is a programmable function.

Keystroke Entry As each key is touched the keypad emits a short beep to indicate that the entry has been stored in the

keypad buffer. This feature can be disabled using the dip switch on the D720 Series.

Faulted Point Protest

Watch Tone The keypad sounder emits a short beep when a watch point is faulted during watch mode. System Trouble

Protective points may be programmed to sound the area keypad buzzer after an arming command is entered, to indicate that a point is faulted.

Some points may be programmed to sound a service tone when they are faulted. To silence the sounder enter an arm/disarm passcode for that area, or enter [COMMAND][4].

Some points, such as fire points, may be programmed so the sounder cannot be silenced until the point fault is corrected. For additional programming information, refer to the appropriate program entry guide (refer to Table 5 on page 5).

perimeter points are armed. During exit delay time, this indicator flashes slowly.

4.2 Point status indicators

The keypad contains eight numbered indicator lights, which are used to annunciate the condition of the area’s protective points (Item 4 in Figure 1).

• Point Fault – While a point is faulted, its indicator

lights steadily. When the point is restored to normal, the indicator goes “off.”

• Point Alarm Memory – A point alarm memory

condition causes the indicator light to flash “on” and “off” rapidly. The indicator continues to flash rapidly until the system is next armed or [COMMAND][4] is entered.

• Bypassed Point – When a point is bypassed, the

point’s indicator flashes “on” and “off” slowly. The indicator continues to flash slowly until the system is disarmed, or with some systems, the point may be unbypassed.
