Holt Alarms

Access Control

Holt Alarms Access Control Systems can be integrated into many existing systems that work to control the flow of traffic to and from specific areas around or within a building.

Access Control Systems can include card swipe, keypads and proximity readers, finger print recognition and biometrics. All Holt Alarms access control systems can be combined to provide different levels of security and personnel authentication including ID cards and PIN entry.

We install a range of access control systems to suit all requirements from stand-alone systems through to the latest most sophisticated IP Networked integrated security systems. Many businesses utilise PC-based systems as a method of restricting movement around a site including the entry of persons into secure areas, or the control of traffic into car parks. A Holt Alarms access control system is a most cost effective way to secure ingress and egress to and from your site.

Benefits of Access Control Systems

  • Access control is very versitile, it can be used on Doors, Gates, Barriers, Lifts. Basically anywhere where there is a physical barrier between two areas.
  • Reduces the need for multiple keys, 1 card or code can be used to access multiple areas
  • Users can be individually setup to have access to specific doors between certain hours
  • Fully time stamped event list showing user movements within the building
  • Networked systems can be setup to generate time sheets for employees
  • Can be integrated into alarm systems so that access will not be granted unless the user has the ability to turn off the alarm system if the alarm system is armed
  • Networked systems can be controlled remotely by a Laptop or even a mobile telephone with the use of software such as TeamViewer

Intercom Systems

Audio or Visual intercom systems work as a doorbell type of system with a call unit and handset. The system allows communication between the call unit and handset without physically having to go to the door. If access is granted electronic locks can release the door momentarily to allow access.

Standalone Systems

This is the simplest type of access control. This consits of eith a keypad or proximity reader that is used to restrict access. Standalone units are controlled locally at the keypad or reader which will hold all the access codes or proximity card details within the unit. Standalone systems must be physically programmed at the unit and generally this type of system cannot be interrogated for previous events.


A networked system is managed from a control unit that communicates to a server running the access control software. All controllers can be programmed and interrogated from a central location, this gives you a much greater level of control to manage the system.
