10.2EXT-Set (Operation with potential free alarm contacts)
10.2.1 Safety notes

Function switch must be shifted to OFF and telephone-cord must be disconnected before any wiring
work is done on the AC-adapter or connecting cable.

All contacts of the EXT port are on telephone circuit potential => therefore any applied alarm
contact must be potential free (relays or opto-coupler) and must have a isolation of lease 3.75kV
according to regulation EN60950.

All contacts have to be protected against any body contact
10.2.2 Wiring plan
Connect the open ends of the sensor-cord to the potential free alarm contacts as shown below and plug the
sensor cord into one of the EXT-ports of the alarm unit.
Connect the open ends of the sensor-cord to the potential free alarm contacts as shown below:
FCC8/6
Plug
Open ends of sensor-cord
PIN 2: White wire (Output)
PIN 3: Black wire (Sensor-2 input)
CAN BE USED AS EMEGENCY MODE!
PIN 4: Red wire (+12V)
PIN 5: Green wire (Sensor-1 input)
PLUG&PROTECT-sensor
PIN 6: Yellow wire (GND)
PIN 7: Blue wire (Sensor-3 input)
CANNOT BE DISARMED!
10.2.2.1 Operation with only one alarm contact (Sensor-1)
If you only need one alarm contact you should use sensor-1-input.
EasyAlarm
®
will auto-detect the contact-
type (

Plug&Protect-Contact) and starts monitoring sensor-1 according to the state of the sensor-2-input at
the time of power-up (details according to section 10.1):
Connect Sensor-2-input to GND => Sensor-1 is a normally closed contact
Let Sensor-2-input open => Sensor-1 is a normally open contact
Select the appropriate contact to fit the monitoring!
10.2.2.2 Operation with up to three alarm contacts (NO or NC)
Select the appropriate contact to fit the monitoring!
Notes:

Sensor-1 monitoring can be disarmed (disable) or sensor-1 can be used for presence verification (

programming according to section 10.2.3.1)

Sensor-2 monitoring can be disarmed (disable) or sensor-2 can be used as a emergency contact (

programming according to section 10.2.3.2)

Sensor-3 monitoring CANNOT be disarmed (

programming according to section 10.2.3.3)
10.2.3 Configuration of the alarm behaviour
10.2.3.1 Sensor-1 monitoring
10.2.3.1.1
Sensor-1 as alarm contact
EasyAlarm
®
auto-detects a Plug&Protect-sensor and starts its monitoring if the system is armed. You can
define the behaviour for sensor-1 as following:
Example: A normally closed contact shall trigger an un-delayed alarm with a hands-free-connection
independent from position of the selection switch.
1. Slide function switch to PROG
2. Enter sequence
* . 9 . 3 . 1 . 7 5 6 # . # .
. .

Current register (bit 7 -> bit 0) will be announced followed by “to modify press * . , to stop press # . “
3. If you want to keep current value proceed with step 6. Otherwise start modifying register by pressing
* .
.
4. Enter sequence 0 . 0 . 1 . 0 0 0 . 1 . 1 . .
Factory default for sensor-1 monitoring
00 0 000 10, => un-delayed alarm in listening-in
connection only on all positions I/II/III
=> connector type: auto-type (plug&protect)
