Why use expansion modules in the alarm system?

The expansion modules (expanders) allow to increase the capability of the control panel – they allow to add new inputs (sensors) and outputs (e.g. siren control, lighting, automation). This makes the system more flexible and can grow with the user's needs.

Most popular types of expansion modules

• Input expanders: Add additional detector lines – e.g. 8 inputs into the INT-E module. {index=0}
• Entrance and exit expanders: Modules such as INT-PP allow to add both inputs and outputs. {index=1}
• Output expanders: Expand the system with additional OC or relay outputs. {index=2}
• DIN modules (rails): Expanders designed for mounting on DIN rail, ideal in switchgears – e.g. INT-IORS. {index=3}
• Addressable expanders: Modules that support addressable inputs – e.g. INT–ADR allows you to add up to 48 inputs. {index=4}

What to pay attention to when selecting a module?

• Compliance with the control panel: Make sure the expander works with the control unit you use (e.g. INTEGRA, VERSA). {index=5}
• Input Configuration: Check which input types the module supports: NO, NC, EOL, 2EOL, etc. :contentReference[oaicite:6]{index=6}
• Outputs: Select an expander depending on your control needs – how many outputs do you need? OC? :contentReference[oaicite:7]{index=7}
• Installation: Do you need a wall mount module, or a rail mount module (DIN)? :contentReference[oaicite:8]{index=8}
• Power supply: Modules typically require 12 V DC – take this into account when designing the installation. {index=9}
• Securities: Check if the module has a tamper input to detect manipulation attempts. :contentReference[oaicite:10]{index=10}

Examples of expansion modules

• **:contentReference[oaicite:11]{index=11}** – Expands DSC control panel by 8 additional entrance zones. **:contentReference[oaicite:12]{index=12}** – Module adding 8 low current outputs to control alarm signals. **:contentReference[oaicite:13]{index=13}** – Expander 8 ROPAM inputs, easy to integrate with alarm systems. **:contentReference[oaicite:14]{index=14}** – 8 input inputs to detectors, ideal for increasing detectors. **:contentReference[oaicite:15]{index=15}** – The automation module with 8 inputs and 8 outputs allows to integrate alarm system with building automation. **:contentReference[oaicite:16]{index=16)** – Module I/O 4 channels from RAD allows additional inputs and outputs in alarm systems.

• Professional advice: We will help you match the module to your control panel and design an extended alarm system.

Frequently asked questions (FAQ)

Can I plug in more than one expansion?

Yes – many systems allow you to cascading the entrance and exit expansions, but you have to check the limitations of your control panel.

How to configure an input type (EOL / NO / NC)?

In the expansion module (e.g. INT‐E, INT-PP) you can set the input type in the control panel software – adjust the configuration to the type of detectors used. :contentReference[oaicite:17]{index=17}

Do I need an extra power supply for expansion modules?

This depends on the load – if you add multiple modules, consider a power supply with more efficiency to ensure stable operation.
