2.
Connect the D279A to the panel and protective zones or points as shown in Figure 2.
•
Install a 1 k
W
EOL beyond the last sensor of both the
Delayed
and
Instant
loops to provide a
reference for supervision.
•
No terminating resistor is needed on the
Burglary
or
Panic outputs
to the panel.
•
If the
Panic
and
Burglary
outputs are connected to the same zone or point, place the J4 jumper on the
bottom two pins (see Figure 3).
•
If the
Panic
outputs from several Independent Zone Controls are connected to the same zone or point,
place the J4 jumper on the bottom two pins (see Figure 3) on all but one D279A.
•
Burglary and panic outputs
: You cannot connect D279A Burglary and Panic outputs to the D6112 or
D4112 powered loop inputs. Powered loop inputs are D6112 Terminals 16, 17, 18, and 19; D4112
Terminals 16 and 17; and D7112 Terminals 23 and 24.
3.
Route the 10-wire color-coded cable through the opening in the back of the enclosure base. Rotate the
conductor so that the red wire (PIN 1) is pointing toward the bottom of the keypad and the orange wire (PIN 10)
is pointing toward the top. Plug the connector into the back of the enclosure.
4.
Place the enclosure base on the wall in the desired location, and mark the locations of the mounting holes.
(The base can be mounted to a single-gang wall box. The two mounting screw holes in the base of the D279A
are positioned for standard single-gang compatibility.) Secure the enclosure base to the wall or gang box.
5.
Push each key on the keypad towards the top of the enclosure to ensure proper mating with the openings in
the top cover.
6.
Align the top two tabs of the enclosure cover with the top two tab slots in the enclosure base. Slide the top of the
cover into the base. Gently push the bottom of the cover down on the base until it snaps into place.
7.
Program the passcode (see section 5.1
User Passcode).
3.2
Connecting the D279A to the D55 Desk Stand
The wiring cable (with modular plug) that is included with the Desk Stand is not compatible with the D279A. To
install a D279A onto a D55 Desk Stand:
1.
Remove the cover as described previously.
2.
Plug the 10-wire cable into the D279A.
3.
Route the cable through the hole in the desk stand.
4.
Screw the base to the Desk Stand, and replace the cover.
To disconnect the D279A, reverse this procedure. The D279A cable plug cannot be removed through the Desk
Stand hole.
