Function

3.1

Detector group inputs

- The 2 detector groups operate with a stabilized voltage of 3.3 V DC.
- End of line resistor programmable: fixed value 12k1 or 10k, freely programmable 4k to 14k
(depending on monitoring area)
- Monitoring area programmable: ±20%, ±30% or ±40%
The states of the 2 detector groups are transmitted separately in the bus protocol via
Triggering of a cover contact
protocol.
3.2

Relay outputs

The module provides 2 relay outputs each with a potential-free changeover contact.
The function depends on programming and operating mode.
Limit values:
4.

Operating modes

The type of module is selected via a solder bridge (see Chapter 5.2).
The set type of module is automatically identified when establishing the connected BUS-2 users.
4.1

Operation as 2-Relay 2-Input Module BUS-2

MB-Secure (from V02)
Conditions:
- The function of the relay outputs and the detector groups is defined via control panel program-
ming.
- Firmware update via BUS-2.
4.2

Operation as 5 Output Module BUS-2

Operation mode MB12/24/48/100/256
Detector group inputs are not supported
Relays are always activated from the control panel via the BUS-2:
- Output 1
- Output 2
- Output 3 – 5
- Tamper monitoring
The cover contact is automatically allocated to the main zone to which the module was allocated.
If the cover contact is triggered, a tamper alarm is signalized in the corresponding zone.
If the module was not allocated to a zone, there is
gered.
