3. Maximum number of devices per 2,500 feet circuit is 40.  

Note:  Each panel allows a speciÞ c number of supervised keypads.  Add additional keypads in the 
unsupervised mode.  Refer to the panel installation guide for the speciÞ 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).  

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.

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

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.

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.  

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.

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, veriÞ es its authority with the panel, and then powers its on-board Form C relay releasing a door 
strike or magnetic lock.
