2026-09-17Last updated

Understand how Bosch input circuit states are mapped and displayed in Security Center SaaS for normally open and normally closed contact types.

Bosch input state mappings

The following tables map Bosch panel input states to the corresponding state shown in Security Center SaaS.
Table 1. Input state mapping for normally open contacts
Bosch panel Single End-of-Line (EOL) resistor - Security Center SaaS Dual EOL resistor - Security Center SaaS
Normal Normal Not applicable
Open Trouble (Open) Not applicable
Short Active Not applicable
RX2 Not applicable Not applicable
Note:
Bosch 5.1.0 intrusion panels don’t support the Normally open contact type for input circuits configured with a Dual EOL (End Of Line) resistor. When this configuration is used, the panel reports the same return states as a Normally closed contact type.
