9a. Connecting Alarm Inputs for Voltage-Free
Make/Break
1. Connect twisted-pairs to alarm inputs that are to
be used: J07 for inputs 1–4 and J08 for 5–8.
2. Connect supply voltage to J09.
This can be taken from J03-3 and -4.
However, for galvanic isolation an external power
supply must be connected to J09 (always used in
CTS 900).

Supply voltage
3. Check that jumpers S06–S13 are inserted for the
corresponding alarm inputs (1–8) that are used
(see dwg below).
• For voltage-free make/break of an alarm
input with common external power supply
both left and right jumper must be inserted
(i.e. in position 1-2 and 3-4).
• For voltage-free make/break of an alarm
input with individual external power supply
(e.g. nurse call) the corresponding jumper
must be in position 2-3.
• Alarm detection requires a current of at
least 0,4 mA.
• Max voltage on make/break alarm inputs
is 48 V.

Jumpers S06-S13:
S08-S13 with jumpers inserted for voltage-free
make/break with common power supply.
S07 with jumper inserted for voltage-free make/
break with individual external power supply.
S06 with jumpers removed for ring signals.
9b. Connecting Alarm Inputs for Ring Signals
1. Connect twisted-pairs to alarm inputs that are to
be used: J07 for inputs 1–4 and J08 for 5–8.
2. Check that jumpers S06–S13 are not inserted for
the corresponding alarm inputs (1–8) that are
used (see dwg. above).
• For an alarm input used for ring signals both
left and right jumpers must be removed.
10. Acknowledgement Input Connection
(Not used in CTS 900.)
1. Connect twisted-pair to ACKN, screw 1 and 2 on
connector J05, (unpolarized).
2. Connect supply voltage to J09. (See dwg at left
above). This can be taken from J03-3 and -4.
However, for galvanic isolation an external power
supply must be connected to J09.
