Semiconductor outputs

Two "open collector" outputs, LOW active, short circuit protected, current limited (50 mA).
- Output 1: Activation of an external buzzer
- Output 2: Activation of the block lock coil (block release)

Data transmission

Data transmission BUS-1
The states of the 4 detector groups are transmitted via 3 addresses from the module to the panel.
The function of the control signals are transmitted via the first two addresses from the panel to the
module.

Data transmission BUS-2
The states of the 4 detector groups and the control signals are transmitted separately in the bus
protocol via one address
Triggering of a tamper by the
protocol.

Programming

Overview

The DIP switches are only queried during initialization with a reset (when the operating
voltage is applied). Therefore, set the switch in de-energized state. The setting of this
switch is then only effective
