For installations where running additional cable isn't practical, our PT Series 433MHz transmitters and receivers offer a useful alternative for suitable switching and signalling applications.

Our range includes single-channel transmitters and receivers, with a choice of open collector or relay outputs. Up to 20 transmitters can be learned by one receiver, and there's a typical operating range of up to 100 metres, depending on the environment.

You can also choose between momentary and latching outputs, giving installers flexibility depending on what the connected equipment needs to do.

They're compact, straightforward products, but there are plenty of applications where a wireless signal can make an installation much easier.

If you're working on something that could benefit from a wireless connection, have a look at the PT Series or speak to us about your requirements.

“Do I need to replace the whole system?” is something customers often ask us.

We speak to installers and customers with existing security or monitoring systems that are still doing their job perfectly well, but one part of the setup needs updating or they want to add something new.

It might be a change to how alerts are communicated, adding wireless functionality where running new cable isn't practical, or introducing remote monitoring to an existing system.
Rather than starting again, it often makes more sense to look at what's already there and find a product that works with it.

That's why we always like to understand the application first. When you contact us, we'll likely ask lots of questions as we'd rather get to the bottom of the real problem rather than recommending technology for the sake of it.

If you're not sure what you need, tell us what you already have and what you're trying to achieve, and we'll help you look at the options.

An auto dialler doesn't have to be limited to one type of alarm system. That's one of the useful things about the Keystone AD06 4G GSM Auto Dialler.

Its six trigger inputs allow it to connect to equipment including alarm control panels, nurse call devices, flood sensors and environmental monitoring systems. Each trigger can have up to nine programmed phone numbers, with the option to send a recorded voice message, SMS notification, or both.

There are also four programmable outputs, which can be operated locally or remotely, including through the free Android and iOS app. Built-in listen-in, programmable test messages and battery backup options provide further flexibility depending on the installation.

So whether you're specifying a new system or looking for a 4G replacement for a PSTN dialler or older GSM equipment, the AD06 provides a practical way to keep important notifications connected.

If you have an application in mind and want to know whether the AD06 will work for it, speak to the Keystone team.

Is your GSM auto dialler ready for the 2G switch-off?

If you look after alarm or monitoring systems, now is a good time to check what’s actually keeping them connected.

The UK’s older mobile networks are being retired. 3G has already been switched off by the four major UK operators, while 2G will follow over the coming years. For older GSM auto diallers, that raises an important question: what network does your existing equipment rely on?

It isn’t necessarily as simple as changing the SIM either. If the hardware itself only supports 2G or 3G, an upgrade will need to be considered.

Our latest article explains what the changes mean, what installers and system owners should be checking now, and how moving to a 4G GSM auto dialler can help keep existing alarm and monitoring systems connected.

If you have older GSM equipment out in the field, it’s worth a read.

What does an auto dialler actually do?

In simple terms, it makes sure the right person knows when something has happened.

Connected to a compatible alarm or monitoring system, an auto dialler can automatically contact programmed users when it's triggered.

That could be an intruder alarm, a safety system, monitoring equipment or another suitable application where somebody needs to be alerted.

Our 4G GSM Auto Dialler can send SMS notifications and make voice calls, giving installers a practical option for new systems or when looking for a 4G replacement for a PSTN dialler.

When making a decision on the right product, there's lots to think about.

Price and features obviously matter, but there are other questions worth asking before making a decision – from the environment it will operate in and compatibility with existing equipment, to reliability, ongoing support and availability.

We’ve put together a few of the things we think are worth considering before choosing an electronic product.

Have a swipe through – and if there’s anything you’d add to the list, let us know in the comments.

And, of course, if you’re trying to find the right product for a particular application, you’re always welcome to ask us.
