Struggling with Signal When the Alarm Panel’s Under the Stairs? Here’s the Fix
Poor intruder alarm communication caused by where the control panel is installed – such as under the stairs, in a cupboard, or behind metalwork – is a common problem for installers. The good news? There’s now a simple, installer-friendly solution.
The RISCO Cellular On-Bus (COB) Module delivers reliable mobile network connectivity, without relying on the end user’s broadband. Because it connects directly to the BUS line and can be positioned up to 30 metres away from the panel, it eliminates common signal issues caused by panel placement. That means stronger communication, fewer call-backs, and smoother commissioning.
Why Reliable Alarm Connectivity Matters More Than Ever
Today’s intruder alarm systems aren’t just deterrents — they’re smart, connected devices that support app control, push notifications, and ARC (Alarm Receiving Centre) reporting. But all of these features rely on one thing: a stable communication path.
As an installer, you’re under pressure to deliver systems that stay online even when:
- the router fails,
- broadband is cut or unplugged, or
- there’s no fixed-line internet available on-site.
This is where mobile connectivity for alarm systems has become essential. Whether as a backup path or the primary means of communication, 4G-based signalling helps ensure uninterrupted performance – and meets the expectations of both end users and ARCs.
What Sets the Cellular On-Bus Module Apart?
Unlike traditional GSM or plug-in modules that require additional power or sit close to the panel, RISCO’s COB Module connects directly to the panel’s communication BUS. There’s no need for an external power supply or extra cabling.
Even more importantly, the COB can be installed away from the panel – up to 30 metres in fact – which means you can position it in a spot with a better mobile signal. That flexibility gives you a huge advantage when working in homes or small businesses where the control panel is hidden under the stairs, behind metal appliances, or in a comms cabinet.
The module supports both Cloud connectivity and Direct IP ARC communication, giving you total freedom to configure the system as needed.
How the RISCO COB Module Helps You On-Site
For installers who regularly work with hybrid intruder systems like RISCO’s LightSYS+, the Cellular On-Bus Module provides a practical way to overcome tricky installation scenarios. Here’s how it makes a difference:
- It cuts installation time with a true plug-and-play BUS connection.
- It ensures alarm signalling remains online, even if broadband fails.
- It acts as a robust backup or standalone path using 4G mobile data.
- It solves real-world problems like poor signal due to panel location.
- And it’s been tested and praised by UK installers in the field.
“As far as I am aware, there isn’t another bit of kit in the market that is as flexible as this is, and I have heard a few installers say that it’s got them out of a difficult situation.”

Who Should Use the Cellular On-Bus Module?
This module is ideal for a wide range of UK intruder alarm installations – whether residential, commercial, or retrofit. It’s especially valuable if:
- You’re fitting alarms in properties with hidden or poorly located routers
- You’re working in rural areas or small retail units with unreliable broadband
- You’re upgrading an older system and need a modern, mobile-ready path
- You want to simplify dual-path configurations with less cabling and setup
Fitting the COB Module – What You Need to Know
If you already work with RISCO hybrid panels, adding the COB Module is straightforward:
- Connect the module directly to the panel’s BUS
- Attach a RISCO-compatible GSM module and insert your SIM
- Configure your communication paths for ARC and app signalling
- Test the system and confirm network stability
That’s it. No extra power, no ethernet runs, and no router reliance.
What SIM Should You Use?
For best performance and easy configuration, we recommend using the RISCO SIM with the Cellular On-Bus Module. It’s pre-configured for RISCO systems, supports roaming across major UK mobile networks, and ensures seamless connectivity for both cloud and ARC communication paths.
Conclusion: Mobile Alarm Communication, Without the Headaches
Mobile communication is no longer just a backup for intruder alarms – it’s quickly becoming the standard. With RISCO’s Cellular On-Bus Module, installers can deliver strong, stable mobile connectivity from the start, even when the panel is tucked away somewhere awkward.
And best of all? It’s simple to install, built for tough real-world conditions, and ready to help you meet customer expectations – without overcomplicating your work.
