Our range includes 4G GSM alarm diallers, PSTN and GSM voice diallers, low-cost 433MHz and 868MHz radio transmitters and receivers, and Netzhome WiFi sensors for connected monitoring and control.

Security & Communication Technology for Professional Applications
Reliable communication is essential when an alarm, monitoring system or connected device is triggered. Keystone Electronics supplies products designed to communicate events quickly and effectively, whether that means making a voice call, sending an SMS notification, transmitting a wireless signal or sending an alert directly to a smartphone.
From a GSM auto dialler for an alarm system to wireless transmitters, receivers and smart monitoring devices, our range provides practical solutions for security, safety, automation and remote monitoring applications.
PSTN & GSM AUTO DIALERS
Our professional auto diallers provide automatic voice and text notifications when an alarm, sensor or other connected system is activated.
The AD06 is a 4G GSM alarm dialler and GSM alarm communicator capable of sending programmable voice messages, SMS alerts or both to selected telephone numbers. With six trigger inputs and four outputs, it can connect to alarm control panels, nurse call devices, flood sensors, environmental monitoring equipment and other multi-channel warning systems.
For compatible installations, we also supply the AD01 PSTN voice dialler, which uses a conventional telephone connection to automatically contact programmed numbers following an event.
Looking to Replace a PSTN or Analogue Alarm Dialler?
Changes to traditional telephone services mean some alarm and monitoring installations require an alternative method of communication.
If you need to replace a PSTN dialler or replace an analogue alarm dialler, the AD06 provides a modern 4G-based option. It can be considered where customers are searching for a 4G replacement for a PSTN dialler, GSM replacement for a PSTN dialler or a suitable PSTN alarm dialler replacement.
Our team can help you assess your application and identify the most appropriate product for your requirements.
Low-Cost 433MHz & 868MHz Transmitters and Receivers
Keystone Electronics supplies a broad range of low-power, low cost 868 MHz transmitters and receivers, alongside 433MHz radio products for wireless switching, security, monitoring and remote-control applications.
The range includes handheld remote-control transmitters, wireless receivers, motion sensors, pagers and multi-channel receivers, providing flexible options for both standalone applications and integration into larger electronic systems. The current Keystone range covers both 433MHz and 868MHz products for general switching and wireless security applications.
Netzhome WiFi Sensors & Smart Devices
Our range of Netzhome WiFi sensors provides straightforward connected monitoring for homes, businesses and specialist applications.
Available devices include WiFi motion sensors, panic buttons, shock sensors, temperature sensors, water leakage sensors, water level sensors and universal normally open/normally closed sensors. Alerts are sent directly to a smartphone or tablet through the Netzhome app, allowing users to monitor events remotely.
The range also includes Netzhome Smart WiFi Plugs for remote equipment control and scheduled operation.
Products for Security, Monitoring & Control
Keystone products are used across a wide variety of professional applications, including security and intruder alarms, nurse call and care systems, environmental monitoring, remote equipment monitoring, wireless switching and control, emergency notification and connected home or business applications.
Rather than offering an unnecessarily complicated product range, we focus on practical electronic products designed to solve specific communication, monitoring and control requirements.
Supporting Installers, Distributors, Wholesalers & OEMs
Keystone Electronics works with customers at every stage of the supply chain.
Security installers and specialist providers rely on us for alarm communication and wireless products that can be incorporated into professional systems. Distributors, wholesalers and catalogue businesses can access established products for resale, while OEM manufacturers can speak to us about product sourcing and specialist requirements.
We can support anything from individual product enquiries through to ongoing and larger-volume supply.
More Than an Electronics Distributor
Our experience extends beyond supplying products from an existing catalogue.
Where an established Keystone product meets your requirements, we can provide a straightforward supply solution. Where something more specialised is required, we can also help identify, source or develop electronic products through our established manufacturing and supply-chain relationships.
This gives customers access to specialist electronic solutions that may otherwise be difficult to source through conventional UK distribution channels.
