SYSTEM 238 Installation Manual

Keypad Wiring

When operated as a Super-

vised Loop, an open will be

reported as a Trouble.

Whether the system is armed

or disarmed. A short on a

Supervised Loop will be re-

ported as an alarm if the

system is armed, but will have

no effect if the system is dis-

armed.

Loop 8

Terminals C and Z8 are a standard loop that can also power 2-wire

devices. It supplies 10 - 12.5 VDC at 50 mA. Use Loop 8 to power

2-wire glass-breaks and smoke detectors.

The SYSTEM 238 is capable of addressing up to 8 Alpha keypads.

LED keypads do not require addressing. Each LED keypad uses 35

mA of current. Each LCD keypad uses 64 mA of current. See

Available Power for current limitations. See page 5 for additional

information on keypad setup.

LOOP INPUTS

Each loop is independently

configured through pro-

gramming. Loops can be

wired with an open circuit

switch, or closed circuit

switch, or with a 2.2K ohm

end-of-line (EOL) resistor.

When programmed as EOL,

either an open or a short will

be reported as an alarm if

the system is in an armed

state.

Fuse F3

The KEY+ terminal is protected by a 0.75 amp, 3 AG, fast-blow fuse

(F3).

Connect the keypad to the control panel as shown in the diagram

above. The Alpha Plus keypad also has a jumper, located near the

piezo, that must be removed when used with the System 238 control

panel.

1. Position the tamper switch inside the cabinet at the lower right

corner of the cabinet. For the wall tamper, the plunger should go

through the small hole in the back of the cabinet. For the door

tamper, the plunger should face out from the cabinet. Refer to

the drawing below.

2. Connect the tamper switches in series and wire the tamper

terminals to a dedicated zone of the control panel.

3. Program the dedicated zone as desired: NC, EOL, 24-hour, etc.

Once the tamper switches are installed, opening the cabinet door or

removing the cabinet from the wall will result in a tamper signal at the

panel.

TAMPER SWITCH INSTALLATION

C&K has designed the SYSTEM 238 cabinet to use the Ademco

Model 19 tamper switch. The cabinet is constructed in order to

accommodate two switches. One tamper for the cover and a second

switch for a wall tamper. To install the tamper switches:

TELEPHONE INTERFACE

Connect the SYSTEM 238 to the phone line using the

9.X PCF cord (not included). The cord has an 8-pin

telco plug on one end. Plug the telco end directly into

the phone companies RJ31 or RJ38X jack. Connect

the flying leads to the SYSTEM 238 PCB as shown

below and listed on the next page.
