Auto dialler systems

Plenty of protected premises are empty at the time they most need looking after. A shop after closing, a warehouse over a weekend, a pump house, a telecom room, a small plant, a farm, a second home — the fire panel or the intruder panel does exactly what it should, the sounder operates, and nobody is there for it. An auto dialler closes that gap by turning the panel’s output contact into a call.

A useful one does three things. It escalates: if the first number does not answer, it tries the next, and the next, until somebody acknowledges. It says something specific — a recorded message or an SMS that names the site and the condition, so the person woken up knows whether to drive there or to call the brigade. And it supervises itself, reporting mains failure, low battery and loss of network, because a dialler that has quietly lost signal is worse than no dialler at all.

We take the contacts from the fire, intruder, leak or plant panel, wire the dialler in, program the escalation list and the messages with the client, and test it by putting each panel into alarm and confirming the call arrives on the phone it was meant to reach. That test is repeated on the maintenance visit, because contact lists go stale faster than anything else on a site.
