670, 770, and 771 Security Command® Keypads
INSTALLATION
Description
The DMP 670, 770, and 771 Security Command keypads
provide an attractive, user friendly control with optional 2button Panic keys for use with DMP Command Processor™
panels. Each keypad provides supervised or unsupervised
operation, an easy to read 16 character fluorescent blue
display, AC LED, backlit keyboard, low profile styling, and
choice of designer colors to compliment a variety of room
decors.
The 770 and 771 keypads also provide four programmable
expansion zones to which you can connect a variety of
burglary and non-powered fire devices. The 771 additionally
provides an internal Form C door strike relay for controlling
magnetic locks or electric door strikes on protected
entrances.
Unsupervised Operation
The 670, 770, and 771 Security Command keypads also
allow unsupervised operation for connecting multiple
keypads to one of the panel's available keypad addresses.
See Address Programming below. This feature greatly
expands the number of keypads you can install to give
users the maximum flexibility in operating their system.
Unsupervised keypads respond to the panel only when
keys are pressed by the user and work on all DMP panels
and 1912XR panels with firmware version 111 or higher.
Address Programming
Use the slide switches numbered 1, 2, and 3 on the left side
of the circuit board to set the keypad to one of the panel's
eight available addresses. See Figure 2.

To disable the 2-Button Panic keys, cut the jumper labeled
"J8" on the bottom left side of the keypad circuit board.
7/0 Panic Keys
The Security Command keypads also allow the user to
initiate a Panic alarm by pressing the 7 and 0 (zero) keys
simutaneously when zone one on the assigned keypad
address is programmed as a Panic type zone.
For the Model 770 and 771 keypads, place a 1k ý End of
Line resistor across the White/Brown pair of zone wires
(zone one).
To disable the 7/0 Panic key feature, cut the jumper labeled
"J7" on the bottom left side of the keypad circuit board.

Figure 2: Supervised keypad addresses
At the beep, the panel sends the following zone alarm
reports to the central station: Panic (left two Select keys) Zone 19, non-medical Emergency (center Select keys) Zone 29, and Fire (right two Select keys) - Zone 39. For
1912XR panels, version 111 or higher firmware is required
for this feature.
The Panic key function is active as soon as you apply power
to the keypad. No additional zone programming is necessary.
If the system owner intends to use the Panic keys, install the
supplied icon label below the top row of Select keys.

The 670, 770, and 771 keypads also provide an optional
Panic key function that lets users easily send a Panic,
Emergency, or Fire report to the central station. The user
just presses and holds two top row Select keys for two
seconds until a beep from the keypad is heard.

Dimming the Keypad Display
Pressing and holding the Command and back arrow keys
for two or more seconds turns off the vacuum fluorescent
display, keyboard backlighting, and Power LED as an
added customer convenience. These indicators are restored
whenever the keypad speaker is turned on or any key on
the keyboard is pressed.
The keyboard backlighting turns off automatically after 30
seconds if no keys are pressed and the trouble buzzer is not
active.

Self-Test Diagnostics
Additional Power Supply
The 670, 770, and 771 keypads allow you to test all
system keypad functions. To test the keypads:
• Disconnect the red (+12 VDC), yellow, and green
keypad wires from the panel.
• Twist the yellow and green keypad wires together.
Reconnect the red wire to the panel.
TEST 1 DISPLAY TEST
This test begins immediately and scrolls a series of
characters across the display allowing you to visually
inspect each display segment.
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 Ground (common) wires to the negative terminal of
the power supply.
To go to the next test, press the COMMAND key. To repeat
a test, press the ARROW key.
TEST 2 KEY TEST
This allows you to check each key for proper operation. The
display shows: PRESS KEY— . As you press and hold each
key, its name is displayed.
TEST 3 ZONE TEST (Not available on the 670 keypad)
This allows you to check each keypad zone for proper
operation. The display shows: L1 L2 L3 L4.
Following each zone number is the status of the zone. (O)
= Open, (–) = OKAY, and (S) = Short.
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 keypads contain an AC LED that's off when AC power
to the panel is off or while the panel is resetting.
771 Door Strike Relay
The 771 provides one Form C (dry contact) relay output for
controlling magnetic locks or electric door strikes on
protected doors. These devices connect to the Violet (N/C),
Gray (Common), and Orange (N/O) conductors on the
harness supplied with the 771 keypad. The relay contacts
are rated for 1 Amp at 24 VDC.
TEST 4 FUNCTION TEST
This allows you to check the AC LED and keypad tone for
proper operation. The display reads: LED RLY TONE. To
test each function, press the select key beneath its name.
The keyboard backlight turns off during this test. The RLY
(relay) function is only available on 771 keypads.
Electrical Specifications
TEST 5 ADDRESS TEST
This test displays the address selection of the keypad. The
display ADDRESS 3 U indicates the keypad being tested
is set to address 3 and is also unsupervised. Supervised
keypads show only the address number. To end the Address
Test, press COMMAND.
You can install individual keypads on wire runs of up to 500'
using 22 gauge wire or up to 1,000' using 18 gauge wire.
Reconnecting the keypad wiring
Disconnect the red wire from the panel. Separate the yellow
and green keypad wires and reconnect them to the panel.
Connect the red wire to the panel. Press COMMAND to
start the keypad's normal operation.
Additional Diagnostics
If a key is pressed and the keypad has not been polled by
the panel within the past 5 seconds, the keypad displays
SYSTEM BUSY.
Also, if at any time during normal operation a supervised
keypad cannot detect polling from the panel for 90 seconds,
the display shows: SYSTEM TROUBLE. This could indicate
a broken green wire, reset jumper installed, or a problem
with the keypad.
The keypads operate on 8 to 16 VDC at 100mA when idle
with the display lit, 110mA with the keyboard and display lit,
and up to 120mA with the buzzer on steady and all lighting
on. The 771 keypad's internal relay can draw an additional
25mA when a door strike is activated.
Mounting Options
For mounting the keypads on solid or uneven walls, you can
use the DMP Model 776 Metal Keypad Backbox. The 776
is 1/2" deep with a baked enamel finish and provides 1/4"
wire entry holes on the back and sides for convenient
wiring.
For applications where conduit is required to the keypad,
use the DMP Model 775 Metal Keypad Backbox. The 775
is 1-1/2" deep with three 1/2" x 3/4" knockouts for connecting
conduit.
To provide additional protection for the keypad against
tampering or unauthorized use, you can install the DMP
Model 777 Plastic Keypad Cover that provides a wallmounted clear 1/8" thick polycarbonate housing with lifting
cover and integral locking mechanism.
If a supervised keypad detects polling, but its particular
address is not being polled, the display shows: NONPOLLED ADDR. To clear this display, check the address
selection on the keypad or the number of keypad addresses
you've assigned during system programming.
