690/790 Security Command LCD Keypads

Description

The 690 and 790 Security Command LCD Keypads provide three 2-button Panic keys, an AC power LED, an Armed LED,

32-character display, backlit keyboard with easy-to-read lettering, and a built-in speaker. The 790 additionally

provides four fully programmable Class B protection zones you can program for a variety of burglary and fire

applications.

The 690F and 790F Security Command LCD keypads do not provide an Armed LED. These keypads may be installed in

fire only applications.

Removing the Base

The keypad housing is made up of two parts: the front, which contains the circuit

board and other components, and the base. To remove the base, insert a flat

screwdriver into one of the openings on the bottom and gently twist it while pulling

the halves apart. Repeat with the other opening.

Installing the keypad

The 690/790 keypads use the same plastic housing and are designed to easily install on

any 4 square box, 3-gang switch box, 695 and

696 backbox, or flat surface. Figure 1 shows

the mounting hole locations on the base of the

keypad housing and the 790 wiring harness.

Harness Wiring

The 790 keypad is supplied with a single 12-

wire harness. Four of the wires allow you to

connect the keypad to the panel's keypad data

bus wiring and the remaining eight are the

four zone inputs. The harness wire colors are

shown in Figure 1. Use 1k Ohm EOL resistors

on zones 1 through 4.

The 690 keypad is supplied with a single 4-

wire harness for connection to the panel's

keypad data bus wiring. The 690 Harness

consists of only the bottom four wires shown

in Figure 1: Black, Green, Yellow, and Red.

Wiring Specifications

When planning a keypad bus installation, keep

in mind the following four specifications:

1. You can install individual keypads on wire runs of up to 500 feet using 22 gauge wire or up to 1,000 feet using

18 gauge wire. To increase the wire length or add additional devices, a power supply is required.

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

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.

3. Maximum number of devices per 2,500 feet circuit is 40. (Note: Each panel allows a specific number of

supervised keypads. Additional keypads can be added in the unsupervised mode. Refer to the panel’s

installation guide for the specific number of supervised keypads that are 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, an auxiliary power supply should be added at the end of the

circuit. The 2.0 VDC drop minimum has not been verified by UL.

Refer to the 710 Module Installation Sheet (LT-0310) for more information. Also see the LX-Bus/Keypad Bus Wiring

Application Note (LT-2031).

-Button Panic Keys The Panic key function of the keypads allows users to send Panic, Emergency, or Fire reports to the central station. The user must press and hold the two Select keys for two seconds until a beep from the keypad is heard. At the beep, the panel sends an alarm report to the central station with the following zone numbers: 19 = Panic, 29 = non-medical Emergency, and 39 = Fire.
PAGE 3
Installer Options The 690 and 790 keypads also contain an Options and Diagnostic program that allows you to configure and test the keypad operation. How to get in You can only access the Installer Options function through the User Options function. After holding down the Back Arrow and COMMAND keys for two seconds and getting the SET BRIGHTNESS display, enter the code 3577 (INST) and press COMMAND. The display now changes to KPD OPT (keypad options) KPD DIAG (keypad diagnostics) and STOP.
