DMP Electronics 791 Easy Entry, 793 Easy Entry Installation Sheet

INSTALLATION SHEET

791 and 793 Easy Entry™ Keypads

Description

The DMP 791 and 793 Easy Entry™ LCD Keypads are the industry’s first burglary/fire keypads with integrated access
control capability.

Each keypad provides three 2-button Panic keys, an AC power LED, an Armed LED, 32-character display, backlit
keyboard with easy-to-read lettering and an internal speaker. The 791 and 793 also provide four fully programmable
Class B protection zones you can program for a variety of burglary, fire, and access control 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
while pulling the halves apart. Repeat with the other opening.

Installing the Keypad

The Easy Entry keypads each
use the same plastic housing.
They both 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
keypad base.

Harness Wiring

The 791 and 793 keypads are
each supplied with one 12-wire
data bus/zone harness and one
5-wire output/reader harness.
The harness connections and
color codes are shown in
Figure 1.

Wiring Specifications

When planning an installation,
keep in mind the following four

Surface and Backbox

Mounting Holes

Figure 1: Back of Keypad with Wire Harness

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.

Refer to the 710 Module Installation Sheet (LT-0310) for more information. Also see the LX-Bus/Keypad Bus Wiring
Application Note (LT-2031).

A separate clamping diode is included with each keypad in the
shipping package. This diode may be installed across the power inputs
of an electromagnetic lock to shunt excessive voltages away from the
keypad. Install diode as shown in Figure 2.

2-Button Panic Keys

The Panic key function of the 791 and 793 keypads allows users to send Panic, Emergency, or Fire reports to the
central station. The user must press and hold the two Select keys 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.

The Panic key function must be programmed if the Panic keys are to be used. See page 4 for programming
instructions. Install the supplied icon label below the top row of Select keys.

Internal Speaker Operation

The Easy Entry keypads emit standard tones for key presses, entry delay, and system alerts. When used with the
XR200, XR200-485, or XR2400F Command Processor Panels, the speaker also provides distinct burglary, fire, zone
monitor, and prewarn tones.The Easy Entry keypads provide an alternate entry delay audible prewarn cadence that
occurs when a zone alarm is displayed in the status list.

Keyboard Backlighting

The Easy Entry keyboards light any time a key is pressed or the speaker sounds. During an alarm condition, the
keyboard turns Red to visually alert people on-site. The Red backlighting is turned off when all areas in the system
are disarmed or when the Sensor Reset function is used. The keypad backlighting dims to medium brightness
whenever the speaker is on.

How the Easy Entry Keypads Work

The 791 and 793 keypads allow users to present a proximity credential to an access control reader that in turn sends
their user code to the keypad. Users can also manually enter their user code into the keypad. The keypad reads the
user code, verifies its authority with the panel, and then powers its on-board Form C relay releasing a door strike or
magnetic lock.

Door Contact Zone with Soft-Shunt™

If the door being released by the keypad is protected, you can provide a 40-second shunt by connecting its contact to
zone 2 (White/Red pair) on the keypad and enabling the Soft-Shunt feature. See ACTIVA TE ZONE 2 SHUNT on page 4
and Door Strike Relay Operation on page 5. Once the door strike relay is activated, the user has 5 seconds to open
the door connected to zone 2. The zone is then shunted for 40 seconds. Door contacts may be N/C or N/O.

Zone 3 Request-to-Exit

You can also connect a normally open PIR (or other motion sensing device) or a mechanical switch to zone 3 (White/
Orange pair) on the keypad to provide a request to exit capability to the system. See ACTIV ATE ZONE 3 EXIT on
page 4. When zone 3 is shorted, the keypad relay activates for 3 seconds. During this time, the user can open the
protected door to start the 40-second Soft-Shunt entry/exit timer. If the door is not opened within 3 seconds, the
relay restores the door to its locked state.

Note: A zone 3 Request-to-Exit is inhibited for 3 seconds after the keypad reads a card and a door strike occurs. This
is to allow entry to area and pass under a Request-to-Exit PIR.

12 VDC Access Control Readers

To use 12 VDC readers with the keypad,
connect the Red and Black power wires from
the reader to the power wires from the panel.
These connect in parallel with the keypad
power wires. Connect the White data wire
from the reader (Data 1) to the White wire on
the 5-wire keypad harness. Connect the Green
data wire from the reader (Data 0) to the
Green/White wire on the 5-wire keypad
