Building Access System - Complete Entry Access Control

The Building Access Control System gives network alarm managers the ability to control and regulate door entry access. With a built-in fault tolerance system this security system can effectively control your sites. You will have complete visibility of all your sites simultaneously, as well as have some record of who was in your building. This provides valuable security to your remote sites and deters theft, break-ins, and vandalism. These are unfortunate realities for remote sites and you cannot afford to leave your site vulnerable. Protect your site and your gear with a Building Access Control System.

Building Access System
Example of an electronic Building Access Control System.

The Building Access System (BAS) is a comprehensive building management system that integrates into an existing alarm management platform. With the system in place, a log of all site access, including the time of day and location that access was granted, is maintained. In addition, alarms such as intrusions and excessive access attempts are reported in real time to T/Mon on a per-door basis.

"BAS is a no-brainer if you already have a T/Mon and a NetGuardian."

The DPS Building Access Control System consists of T/Mon, the NetGuardian 832A, the Entry Control Unit, and a Proxy Reader.

With a Build Access Control System, you will:

  • Centralized entry access control and management.
  • Controls and regulates up to 16 door entry points (*8 per RS485 port).
  • Support up to 1,300 users.
  • Users can be granted access by day of the week, time of day, and location.
  • New! Now available - Electromagnetic door locks.
  • Support up to 16 doors per site.
  • Access Control Remote Units function independent of master.
  • System can withstand connectivity losses to the local NetGuardians and T/Mon.

BAS Software Module

The BAS functions as a software module in T/MonXM software. It is a profile-based remote access control system. It assigns each user with a unique user profile containing information. Which sites are allowed to be accessed, the door numbers, days of the week access is allowed, a start/stop time, and a beginning and ending date (primarily for contractors, new employees, or short term employees).


Integrate a Building Access Control System into your T/Mon LNX alarm master management platform. The BAS can work with T/Mon Master to give you a single centralized physical access control of remote site access. You will have visibility of all your sites, no matter how far, all from your central office. With the BAS and the T/Mon working together, your sites will always be monitored, saving you time, money and customers. Additionally, you can support over 1,300 user assigned profiles, and the T/MON can mediate over 25 proprietary protocols. This ensures your whole system and all your existing gear in your Building Access Control System can integrate seamlessly. You will not have to replace legacy or other existing equipment.

NetGuardian 216F

The NetGuardian 216F controls local access at your remote sites. The unit maintains a list of personnel who are authorized to access the facility. It records all valid entries, attempts, and the time of each action in non-volatile RAM. It can also receive a control from T/Mon to remotely open an external access door. However, should the NetGuardian lose connection with the T/Mon , the unit is still able to make local entry decisions. The NetGuardian contains a mirror user database from T/Mon and will continue to function if the link is broken.

The NetGuardian 216F indicates conditions such as valid entry, invalid access attempt, and system lockout. The unit supports up to 1,300 user profiles for distribution between door entry points.

Building Access 32

The Building Access 32 interfaces to your door access controller, proxy key key card readers, and T/Mon Alarm Master. While a variety of NetGuardian RTUs can also handle this function, the Building Access 32 is ideal for high-density scenarios where you have a lot of doors to control and monitor. The Building Access 32 does not require external Entry Control Units (ECUs) to be placed near each door. It communicates directly with your proximity readers. Also, because the Building Access 32 does not include the network alarm monitoring functions of a traditional RTU. It is more cost-effective at sites where you don't have telecom gear to monitor, such as your main office or storage facilities.

Entry Control Unit

The Entry Control Unit, or ECU, acts as an interface between the NetGuardian and the proxy reader. Any access code that is entered is accepted by the ECU and passed on to the NetGuardian for validation. If the access code is valid, the ECU receives a command from the NetGuardian to operate the local relay to energize the door. In the event of communication failure with the NetGuardian, the ECU will verify entered access codes against a small fallback set. The fallback set consists of valid access profiles that were downloaded from the NetGuardian.

The ECU is powered by -48VDC and is wall mountable on the interior of the building. The unit has LEDs for power, communication, fuse alarm, and an LED that that echoes the door status.

The Proxy Reader

A proximity key card reader is now available for the BAS. This eliminates the chance of forgotten keycodes and increases your level of access control. An employee can easily share a keycode with others, but not proximity cards. In the event that a key card is lost or stolen, it can be deactivated in seconds and a new key card may be issued in its place.

Building Access Proxy & Keypad (BAPKP)

A Building Access Proxy & Keypad (BAPKP) is now available for the BAS. Supporting both proximity keys and key cards at a remote site increases your flexibility. Regular employees can quickly wave their proximity key, while other authorized visitors can enter a temporary code to gain access. The BAPKP is a compact entry device that houses both a weather-resistant keypad and a proximity key card reader.

New BAS Features

"Extended Propped Door" Mode When activated, Extended Propped Door Mode allows the specified exterior access door to remain propped open without triggering a propped door alarm. This is useful during gear installations that require frequent entries. When the door is closed, it will lock until you deactivate Extended Propped Door Mode.

"Stay Open" Mode

Stay Open Mode allows a door to remain unlocked. One typical application is for a front lobby. In the morning, your receptionist can scan a special key card. The door will then remain unlocked for business. At night, when the same key card is swiped again, the door will lock.

Door control systems are just one component of a physical security system. Learn more about managing physical network security systems with remote monitoring systems.
