Chevron Alarms can supply and install door access control systems, to secure or control access to external and internal doors within a building. There are several different systems available; stand alone system controlling one or two doors or computer based systems that can control hundreds of doors with potentially thousands of users.
This is a traditional type of system installed into Flats and Offices. The main external entrance door remains securely locked. When a visitor arrives at the building, they would push a call button on the door entry panel to operate a sounder in the flat or office. By picking up the telephone style handset in the flat or office you can have a two way conversation with the visitor and by pushing the release button on the handset the external entrance door can be electronically released, allowing the visitor to enter.
As described in the above system, but with a small camera built into the external entrance control panel and a LCD monitor incorporated within the telephone style handset. This will give a visual image of who is at the external entrance door.
Electronically locked doors can be unlocked by placing a proximity tag or card on the reader. Each tag or card can be programmed to give different access levels thus controlling the passage of people throughout the building. These systems can be linked into a computer to give a greater level of control and programming e.g. visual verification, payroll, clocking in and out etc.
As described in the above system, but using magnetic swipe cards and readers instead of proximity.
These would be installed on designated doors. By entering a secret code number, a magnetic lock is released to gain access. These can be a standalone system or several can be linked into a computer controlled system.
Chevron Alarms can design and install Intruder alarm systems to satisfy any requirement to protect either your home or business.
