VEDOGSM module SIM installation guide

Which SIM does the Comelit VEDOGSM take?

A micro SIM (3FF), voice/SMS-capable, PIN lock off. The VEDOGSM is an expansion module for Comelit's Vedo alarm panels rather than an intercom — it gives the alarm a cellular path for signalling and control, which makes it a close cousin of the gate-side GSM kit and a common sight on the same properties.

Which network?

It's a 2G module, so it needs live 2G at the panel's location — usually indoors, which cuts signal further. A multi-network SIM gives it the strongest surviving 2G locally and re-registers as the picture changes; for an alarm path, silent failure is the thing to engineer against.

Fitting the SIM

For the installing engineer, with the Vedo panel powered down per Comelit's procedure:

1. Fit the micro SIM in the module's holder.
2. Seat the module in the Vedo panel per the technical manual.
3. If signal indoors is thin, use the module's antenna options to get the antenna somewhere useful.

First power-up

Bring the panel up, let the module register, and configure the signalling numbers per the Vedo documentation. Test an actual event end to end — trigger, SMS/call arrives — not just registration.

If it won't connect

• No registration indoors: antenna placement before anything else.
• Registered, no alerts: credit and the panel's event-to-number mapping.
• Intermittent: marginal indoor signal — external antenna.

FAQ

Is this an intercom? No — alarm signalling. Same SIM logic, different job.

2G future? Limited; Comelit's newer modules are the upgrade path.

Voice or data? Voice/SMS for signalling.
