Integrated Systems (With Access Control and Phone Systems)

Croma Fire and Security provides integrated systems that connect intercom technology with access control platforms and internal phone systems. These solutions support coordinated communication and entry management across commercial premises. Integrated systems allow organisations to manage visitor access, staff communication, and building security through connected technologies.

Our engineers design integrated systems that link intercom units, door access equipment, and telephone infrastructure into a single operational framework. This approach allows calls from entry points to be directed to internal phones or access control stations, enabling staff to speak with visitors and manage door entry from their existing communication devices.

Integrated System Installations

Croma Fire and Security installs integrated systems following a detailed assessment of the building layout, communication infrastructure, and access requirements. The system design ensures entry points, communication devices, and security equipment operate together. Once implemented, our integrated systems support structured communication between visitors, staff, and building access points.

Features

Access Control Integration

Integrated systems can connect intercom equipment with access control technologies. This allows authorised users to manage door entry while communicating with visitors through the same connected platform.

Phone System Connectivity

Integrated systems can link entry panels directly with internal telephone systems. When a visitor activates the intercom, the call can be routed to designated phones or extensions within the building.

Centralised Communication

Integrated systems allow communication from entry points to be managed through connected devices across the premises. Staff can respond to visitor calls from configured phones, intercom stations, or access control interfaces.

Remote Door Release

Integrated systems support door release functionality that allows authorised users to unlock entrances through connected phones or access control units after verifying the visitor.

Multi Entry Management

Integrated systems can support multiple entrances across larger buildings or sites. Each entry point can be connected to the communication and access infrastructure used within the premises.

System Coordination

Integrated systems allow intercom, access control, and communication technologies to operate together. This coordinated structure supports organised management of entry requests and visitor communication.

Scalable Infrastructure

Integrated systems can be designed to support expanding premises or additional access points. Additional devices and entry panels can be connected as operational requirements change.

Maintenance and Servicing

Routine servicing supports the continued operation of integrated systems. Engineers can inspect communication links, access equipment, and intercom units during scheduled maintenance visits.

Giles Brand — Bursar, St Mary’s School Ascot

I see tangible payroll savings in the order of 2-3%. Our sites are usually about 35 workers; we are saving £400-£500 a week and are in much better control

Luke Sanders – Project Manager, LTS Refurbishment

We have been delighted with the Fastvein system and the care given to us by Croma. From design meetings to commission, the staff were knowledgeable, helpful and courteous.

Integrated Systems (With Access Control and Phone Systems) FAQs

Can integrated systems work with existing infrastructure?

Yes, integrated access control and phone systems can often be tailored to work with your current security setup and telephony network. This helps reduce installation costs and ensures smoother adoption of enhanced security features without replacing existing systems entirely.

How can integrated systems improve my building’s security?

By combining access control with phone systems, you can authenticate users, monitor entry points, and communicate instantly with staff or visitors. This reduces security gaps, enhances response times, and provides centralised management of both access and communication.

What are integrated access control and phone systems?

Integrated access control and phone systems combine physical security (such as door entry and access control) with communication tools like telephony. This allows seamless management of visitor access, staff communication, and site security through a unified platform.
