D205 Keypad Installation
Instructions
Installing the Keypad
Select a Mounting Location - Do not locate the D205
in an area of extreme cold (example: a non insulated
building, refrigerated room, outdoors, or where the
temperature can drop below 32F
°
). Do not mount in a
location exposed to direct sunlight, as the display will
become less visible and inner components may
become damaged.
Route the Keypad Wire - Route the wire to the
mounting location. See the panel's installation manual
for information about maximum wire lengths and wire
resistance. Route wires away from electrical, tele-
phone, and other data wiring.
Wire the Connector - The three-wire connector
attaches to the keypad wire. Use solder to splice the
wires together. Be sure to insulate all exposed splices
with tape to eliminate shorts.
Remove the Front Cover - Remove the front cover
from the enclosure base. Use a small flat-bladed
screwdriver to gently push the two bottom cover-tabs
back. As you push back the tabs, lift the bottom of the
cover away from the base, then remove the cover.
To use the D205 with the D2112: Cut and remove the
R30 resistor. See Figure 2.
If disabling sounder, do so before connecting the
keypad to the wire: To disable the sounder, cut and
remove the R7 resistor. See Figure 2.
Description
The D205 Keypad is a low-profile, surface-mount,
three-wire unit designed for use with the Radionics
D2000 series Control/Communicators. The D205
features an illuminated keypad, an LED display, three
programmable emergency keys, and a built-in sounder
that emits several distinct tones.
The control/communicator supplies all power and data
requirements for the D205 using a simple three-wire
connection.
The Display
LEDs are used to display system status. When events
occur that affect points, the D205 illuminates the LED
that corresponds with the point number.
The Keys
The D205 Keypad has a CLEAR key,
three program-
mable emergency keys, and number keys from 0 to 9.
These keys are used to enter functions and personal
passcodes into the panel. The * key is not used.
Response Tones
The D205 Keypad uses a sounder to annunciate
system conditions. You can disable the sounder if you
choose.
