Fire Detection

We design and install fire protection systems for use in residential, commercial and industrial applications, based on a detailed fire risk assessment. Our systems comply with current fire regulations and legislation, and we offer a scheduled testing, servicing and maintenance service. 

Our systems are tailored to the category and type of alarm system required for your premises and combine carbon monoxide, ionisation, optical smoke, flame and heat detectors as well as rate of rise or fixed temperature sensors. For larger buildings, we can also supply beam smoke detectors.

Sprinkler Systems

Correctly installed fire suppression or sprinkler systems are a vital safety measure which can save lives as well as protect property and mitigate damage in the event of an emergency — and maintaining an up-to-date system is an important factor in minimising insurance costs.  

Our certified engineers can design, supply and install wet pipe, dry pipe, deluge, and pre-action systems, using third-party tested and approved hardware and components. We have experience in both domestic and commercial implementations, including high-volume and specialist industrial systems. 


CCTV and video surveillance systems are a vital part of any building or site’s security provision. As well as intrusion detection and recording criminal activity, they can play an important role in detecting emergency situations, monitoring crowd flow and behaviour, as well as providing footfall analysis.  

JLM offers a comprehensive video security service combining system design, supply of equipment, installation, testing and maintenance. Our systems incorporate fixed, PTZ and specialist cameras, such as thermal imaging or IR, offsite or cloud-based video storage and advanced management and analysis platforms.

Intruder Alarms

Commercial intruder detection and alarm systems are a valuable tool for businesses — not only to protect their property and prevent loss but also to meet insurance, supply chain and regulatory obligations, and ensure employee and customer safety in and around the premises. 

We’ll design, install, and configure an intruder detection system tailored to the specific characteristics of your property, including motion and shock detectors, keypads, panic buttons, smokescreens and deterrent signage — all seamlessly integrated with CCTV/video surveillance and access control systems.

Access Control

Implementing smart access control systems can reduce management, administration and manned security costs while offering greater flexibility to residents, employees, contractors or visitors — and as well as crime and loss prevention, smart access systems can reduce insurance premiums.  

JLM provides fully-customised access solutions which can incorporate smartcard, mobile phone app or keyfob entry, biometrics including fingerprint or face detection, as well as zonal and time-based controls, all managed from a centralised web portal which can be accessed remotely. 

Automated Gates

Implementing automated gates to restrict access to your property gives greater flexibility and incurs lower costs than relying solely on manned security checkpoints or key sharing. Automated security gates allow 24/7 access while controlling the inward and outward movement of people or vehicles.

We provide custom-designed automatic gating solutions, tailored to the exact requirements of your business. Options include swing or sliding vehicle gates as well as pedestrian-only options, with additional features including alarms or beacons, force testing, integrated access control systems and anti-climbing measures. 

AOV/Smoke Vents & Clearing

Automatic opening vent (AOV) control systems are used in the event of a fire to control the ventilation of smoke and clear internal spaces more effectively, reducing the risk of harm to people or property. AOV systems are required in many new builds and may also be retrofitted to existing premises. 

We provide fully integrated AOV systems, including detectors, triggers, call points and actuators in single or multi-zone configurations, depending on the exact characteristics and requirements of the space, as well as extensive testing and ongoing maintenance.

Nurse Call/Disability Alarms

Disability or nurse call alarms offer greater personal security for disabled or vulnerable people using commercial or residential facilities, by allowing easy access to summon assistance in the event it is required — either via fixed-button or cord-pull alarms or via wearable call buttons or wrist monitors. 

We’ll work with you to design the best system for your unique circumstances, taking into account the risk profile of residents or visitors to your premises. We can integrate alarm systems with call centres or security offices to provide fast-response cover, and we provide full testing and maintenance of the systems.  

Solution Design

Our designers will work closely with your team to capture requirements, assess risks and agree on budgets and time constraints. Working from your existing plans or conducting on-site visits we’ll then deliver a comprehensive project design for your approval. 

We don’t have exclusive partnerships with any one manufacturer or distributor, so you can be sure our designers are focused solely on delivering the most efficient and cost-effective solution for your needs.

Project Management

As a full-service engineering firm, we’re experienced in managing infrastructure projects across a wide range of industries and at any scale. We offer a comprehensive project management service to alleviate the pressure on our clients' in-house teams during project delivery.

From the initial briefing, through the design stage and on to installation and ongoing support, you’ll be assisted by a dedicated project manager who will coordinate suppliers, inspections, testing, compliance, health and safety and more — leaving you to focus on running your business. 

Servicing & Maintenance

Regularly scheduled testing, servicing and maintenance are crucial to prolonging the life of your infrastructure and equipment — and protecting your investment. We offer comprehensive preventative maintenance packages that fit around your workflows to minimise downtime or interruptions. 

For emergency or short-notice scenarios, JLM has engineers on standby to attend callouts across the UK on a 24-hour basis, fully qualified to address any electrical or mechanical issues and get you back up and running as quickly as possible.
