Design & Manufacturing.

Electronics for Alarms & Security Systems.

Designing circuit boards for bespoke fire alarms and door entry panels.

With over 50 years of expertise, Winter & Smith have been at the forefront of electronics manufacturing, delivering reliable security solutions. From bespoke alarm systems to advanced security technology, our in-house PCB design and manufacturing ensure top-tier protection for homes and businesses alike.

Secure, keyless security access for empty properties

Managing access to empty buildings can be challenging, especially when dealing with multiple contractors or security personnel. Our Door Entry System eliminates the need for multiple keys, providing a hassle-free and secure entry solution.

Key features include:

  • Battery-powered operation – Runs for up to 18 months without requiring mains power.

  • Standalone entry (version 1): Uses one-time, self-destructing PIN codes for added security.

  • Internet-enabled entry (version 2): Allows remote PIN code changes and access monitoring.

  • Internet-enabled with alarm (version 3): Includes PIR motion detection and a siren, providing an all-in-one security system.

This system is ideal for properties with steel security doors, allowing authorised personnel to enter securely and efficiently while maintaining complete control over access.

 

Security systems for vacant sites

Vacant properties are easy targets for trespassers, vandalism, and unauthorised access. Our Void Property Alarm System is a powerful, battery-powered solution designed to keep these spaces secure for up to 18 months without mains power.

This system offers:

  • Wireless PIR sensors for motion detection

  • Wireless smoke alarms for fire safety

  • Gas leak detection for added protection

  • Lone worker safety with an integrated panic button system

  • Remote monitoring of building access and contractor working hours

  • An integrated speech system for easy operator use

Whether it’s a single vacant site or a portfolio of properties, this system ensures security and oversight with minimal maintenance.

Bespoke security & fire solutions

Beyond alarms and entry systems, we provide a range of advanced security solutions tailored to different industries and environments:

  • Vandal-resistant alarm activation panels – Installed at every UK branch of Nationwide Building Society for high-traffic security.

  • Micro internet alarm system – A battery-powered, compact alarm system designed for small empty flats and apartments, offering cost-effective remote monitoring.

  • Wireless mesh network keypads – Allow secure access to hidden alarm panels, ensuring ease of use without compromising security.

  • Stainless steel door entry panels – Designed for tough environments like Sainsbury’s food warehouses.

  • Bespoke fire alarm monitoring systems – Custom solutions installed at major sites including Telehouse Docklands, the Museum of London, and the Conoco Fuel Depot in Cliffe, Kent.

In-house security PCB development

Unlike other companies that outsource their PCB manufacturing, Winter & Smith designs and builds PCBs in-house.

  • Tailored to you – We can create custom PCBs specifically for your needs, ensuring that all components and connections are optimised for integration and long-term performance.

  • Higher quality – By controlling the entire production process, we ensure that every board meets high-quality standards

  • Faster problem solving – If an issue arises, we can quickly modify and produce updated PCBs without waiting for external suppliers, getting your systems back up and running
