Access Control
PES Southern designs and installs access control systems to manage building security. These systems monitor personnel movement, restrict unauthorised access, and integrate with fire safety protocols. Clients benefit from custom solutions including swipe cards, keypads, and video intercoms.
Intruder Alarms
We supply and install intruder alarm systems ranging from basic bell-only units to police-monitored systems. Our solutions include detectors, sounders, and remote monitoring integration. Insurance-compliant installations ensure rapid response to confirmed break-ins.
Registered Key System
This patented system prevents lockouts and unauthorised key duplication. Replacement keys arrive within four hours, with no need to change locks between tenants. The system offers enhanced security against picking, drilling, and bumping techniques.
Grilles & Gates
Custom-designed grilles, gates, and railings combine security with aesthetic appeal. Our installations meet police and insurance standards while maintaining ease of operation. Bespoke fabrication ensures compatibility with existing architecture.
Planned Maintenance
Regular maintenance contracts cover mechanical and electronic security systems. Our engineers inspect locks, door mechanisms, and electronic components to prevent failures. Scheduled visits ensure compliance with health and safety regulations.
