Alarm inputs and outputs certified with EN 50131-1 Grade 4

Balanced inputs and outputs

At first glance, it may not be clear how balanced inputs and outputs relate to cybersecurity, but the connection is simple. Our customers use them to limit physical access to network infrastructure. Typically, these are door contacts and PIR sensors connected to the alarm inputs of LAN-RING switches, and IPLOG outputs are connected directly to alarm panels.

Alarm inputs

Inputs IN1 and IN2 on LAN-RING switches configured to ALARM mode. In this mode,
measures input resistance from 0 to 30 kOhm.
Thus, they allow to detect PIR sensor states such as normal state, alarm, tamper, fault, etc.

Alarm outputs

The BO outputs on IPLOG controllers and BO8.1-05 modules are alarm resistive outputs with 8-bit resolution.
