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.
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:
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.

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 outlined in the next column:
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 sys-
tem is armed, but will have no
effect if the system is dis-
armed.

9.X PCF
The 9.X PCF has eight flying leads. Wire them to the PCB terminals
as follows:

GREEN = tip
GRAY = ring seized

SYSTEM START-UP

Five minutes after the panel is powered up, it will dynamically test the
standby battery by interrupting AC power for two minutes and monitor-
ing the battery under load.

If you replace the battery after a SYSTEM TROUBLE - LOW BATTERY
message, you must test the battery under load conditions. Press [*] [6]
[4] [#] to start the Dynamic Battery Test.
NOTE: Some keypads may use [SHIFT] and [ENTER] in
place of the [*] and [#] keys, respectively.
Voltage Variations
Output voltages at terminals 5, 7, and 8 may vary between 9.0 and
14.4 VDC (worst case), depending on the load, battery condition, and
AC line voltage.

KEYPAD SETUP

ALPHA KEYPAD INFORMATION
The Alpha keypad uses a top viewing display. This means the display
reads most clearly when viewed from a top angle rather than straight
on or from below. Mounting the keypad at the light switch level and
adjusting the viewing angle gives the best viewing results.
