Our security systems make use of the most up to date technology and provide a way for you to communicate with users who do not have access to your protected area. The most common system to provide this kind of security is the intercom system.

The systems generally comprise of a connection from the point of entry to the protected area and is controlled from inside the area by a user. At CID Fire & Security, we are proud to offer installation in both the public and domestic sectors

The setup is usually wired from the door to a point inside the protected are where there is generally a telephone unit to complete the intercom circuit. When a button is pressed on the intercom for entry to the protected area, the phone will ring notifying the inner area that there is someone seeking entry. The phone end of the system has an allow access button, that, while depressed enables the user at the intercom access to the area.


We can provide small systems, or single point systems to help protect any area. We offer a robust vandal-resistant door entry that is quick to install and provides a complete solution for student accommodation and has various applications in the private sector.


Many features have developed over the years to improve the traditional intercom system that CID Fire & Security offer to you.

Video entry systems are becoming more common as an added layer of security. This allows you to have a visual confirmation of anyone trying to gain access to the secured area.

Wireless intercom systems are very similar to the traditional phone and intercom system. The main feature of a wireless system is that it allows for the central security station to be mobile and allows greater flexibility in the working environment in the protected area. We can add additional internal handsets for allowing access to the secured area. This sort of system is very beneficial for areas where cabling from the entrance and the property is more difficult.

GSM intercom systems are quite similar to the wireless intercom systems; however, they require a sim card that will call up to four mobile or landline numbers. The access is granted by inputting a hash and number code after answering the call. The sim card should be either pay-as-you-go or a contract sim.
