Keypad Entry Delay

All Systems

Once the entry delay starts, the keypad sounds an entry tone and displays ENTER CODE: - . Present your card to

the reader. Once validated, the system disarms all areas accessible by you and activates the 7073 Door Strike relay.

Area systems provide a delay to allow selected areas only to be disarmed. See Keypad Arming and Disarming.

Entry delay starts.

The System disarms the area and activates the Door Strike Relay.

Wiring Specications

When planning a keypad bus installation, keep in mind the following specications:

1. DMP recommends using 18 or 22-gauge unshielded wire for all keypad and LX-Bus circuits. Do Not use

twisted pair or shielded wire for LX-Bus and keypad bus data circuits. To maintain auxiliary power integrity

when using 22-gauge wire do not exceed 500 feet. When using 18-gauge wire do not exceed 1,000 feet.

Install an additional power supply to increase the wire length or add devices.

2. Maximum distance for any one circuit (length of wire) is 2,500 feet regardless of the wire gauge. This

distance can be in the form of one long wire run or multiple branches with all wiring totaling no more than

2,500 feet. As wire distance from the panel increases, DC voltage on the wire decreases.

3. Maximum number of devices per 2,500 feet circuit is 40. On XR500 Series and XR2500F panels, the maximum

number of LX-Bus devices per 2,500 feed circuit is 25.

Note: Each panel allows a specic number of supervised keypads. Add additional keypads in the

unsupervised mode. Refer to the panel installation guide for the specic number of supervised keypads

allowed.

4. Maximum voltage drop between the panel (or auxiliary power supply) and any device is 2.0 VDC. If the

voltage at any device is less than the required level, add an auxiliary power supply at the end of the circuit.

When voltage is too low, the devices cannot operate properly.

Refer to the LX-Bus/Keypad Bus Wiring Application Note (LT-2031) for more information. Also see the 710/710F

Module Installation Sheet (LT-0310).
