3. Maximum number of devices per 2,500 feet circuit is 40.
Note:
Each panel allows a speci
Þ
c number of supervised keypads. Add additional keypads in the
unsupervised mode. Refer to the panel installation guide for the speci
Þ
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 710 Module Installation Sheet (LT-0310) for more information. Also see the LX-Bus/Keypad Bus Wiring
Application Note (LT-2031).
Voltage Protection Diode
Each keypad includes a separate clamping diode. This diode may be installed across an electromagnetic lock power
inputs to shunt excessive voltages away from the keypad. Install diode as shown in Figure 2.
Note: The diode banded end
must be connected to the
supply voltage positive side.

2-Button Panic Keys
The Panic key function of the 693, 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
•
39
=
Fire
You must program the Panic key function in order to use the Panic keys. See Programming Instructions later in this
document. 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, XR2400F, or XR500XR500N Command Processor Panels, the speaker also provides distinct burglary,
Þ
re, zone monitor, and prewarn tones. The Easy Entry keypads provide an alternate entry delay audible prewarn
cadence that occurs when a zone alarm displays 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 on-site staff. The Red backlighting turns 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 693, 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, veri
Þ
es its authority with the panel, and then powers its on-board Form C relay releasing a door
strike or magnetic lock.
