Inputs 1 – 8 for NC contact alarm
• Usually in NC mode (NC = normally closed, i.e. the contact opens in case of alarm).
How to connect an NC contact alarm:
This sketch shows an example for connection of the alarms with NC contacts.

• Unused alarm zones remain closed with the help of the short circuit bridges.
Signal lamp output (max. 40 mA)
The following signal outputs are available:
Connection “RE”: Alarm system ready for operation
Connection “AL”: Alarm system has triggered (alarm is activated)
Connection “AR”: Alarm system is armed
Each output delivers a voltage of 12 V/DC when activated ((max. 40 mA each). Therefore,
a suitable dropping resistor must be used when connecting an LED.
Output for external operating element (REMOTE)
Connection for an optional switch installed in another location in the building to arm and deactivate the
alarm system.
Alarm outputs (NO/NC)
• Output 1: For connection of an alarm flash or automatic dialling device
• Output 2: For connection of an alarm horn (12 V/DC, max. 1 A)
• Both alarm outputs are potential-free relay contacts
• Voltage supply terminals with DC 12 V output
Voltage supply terminals with DC 12 V output
Both positive and negative terminals can be used to feed sensors, alarms, streakers and alarm sirens with
DC voltage (12 V/DC, max. 1 A).
