Address Programming
Each 781 keypad must be programmed with its own device address. This
addressing is done through the use of slide switches located on the left side
of the keypad's printed circuit board. To set the switches, use a small slotted
screwdriver and gently slide the switch to either the up or down position
according to the address table to the right.
Programming Access Cards into the System
Once the 781 keypad is installed and operational, you can begin programming user information into the panel. To do
this, access the USER MENU and select USER CODES?. Then choose ADD. When the keypad displays ENTER
CODE: - , present the user's card to the reader. The 781 works by reading the 4 or 5 digit user code from the data sent
by the access control reader. For more information, refer to the Security Command User's Guide section on adding,
deleting, and changing user codes.
Panic Signal
The 781 keypad can also provide users with a panic feature by programming loop 1 as a panic loop and installing a
1k ý resistor across the White and Brown wires. Afterwards, pressing the 7 and 0 keys simultaneously shorts loop 1
and sends a panic report to the panel. The loop returns to normal when you release the keys. This feature can be
disabled by cutting the jumper J3 on the lower right corner of the keypad circuit board.
Electrical Specifications
The 781 keypad operates on 6 to 16 VDC at 100mA maximum with an unlit display. Current increases to 125mA with
the display lit. You can install the 781 on individual wire runs of up to 500' using 22 gauge wire or up to 1,000' using
18 gauge wire. Below are specifications for individual readers:

35mA at 5.5 VDC
644 Pass-Through Mag Stripe Reader -
35mA at 5.5 VDC
Additional Power Supply
If current draw for all keypads connected to the panel exceeds the panel's output, you can provide additional current
by adding an auxiliary power supply. Connect all keypad common wires to the negative terminal of the power supply.
Run a jumper wire from the power supply's negative terminal to terminal 10 of the panel. Connect all keypad power
(+12 VDC) wires to the positive terminal of the power supply. Do NOT connect the positive terminal of the power supply
to any terminal of the panel.
AC LED
The 781 keypad also contains a green AC power LED. This LED is off when AC power to the panel has been interrupted
or while the panel is resetting.
Door Strike Relay Specifications
The 781 keypad provides one Form C (SPDT) relay for controlling door strikes or magnetic locks. Three wires, violet,
gray, and orange, provide for connection to the N/C, Common, and N/O contacts of the relay. The contacts are rated
for 1 Amp at 24 VDC or 0.5 Amp at 120 VAC.
