Archivo General de la Nación

Complete Building Management Control - Early Detection, Environmental Visibility & Energy Management

AT A GLANCE

Archivo General de la Nación (AGN), translated to the General Archive of the Nation, is a decentralized body of the Mexican Ministry of the Interior responsible for safeguarding and archiving national documents fundamental to Mexican history.

In 1982, the AGN was moved to an old prison bunker complete with armored concrete walls, ceilings and floors. The 4-floor facility, located in the heart of Mexico City, houses one Archive Storage Room per floor in each of its 20 expansive blocks. The fortress-like aura justly represents its importance as a source of genealogical and historical  information and records related to Mexican history, culture, and people. Protecting  the  integrity of these collections is a priority for AGN officials, and Mircom was chosen to provide a comprehensive analysis of their building management system.

CHALLANGE

Given the complexity of heritage document preservation, AGN officials knew it was necessary to have early fire detection and complete monitoring and control of the environmental conditions within each of the archive storage rooms. They issued a three-part challenge:
DETECT fire in its early stages to prevent irrecoverable damage
AGN official knew that the biggest threat they, and all cultural institutions, face is from fire and the ensuing harm done by water and chemicals used to put it out. No institution is immune to fire, and its damage is usually permanent and irreparable. Once reduced to ash, historical buildings or contents can never be restored, so early detection was a priority.
MONITOR the environmental conditions in each room
Given the sensitivity and age of the archived documents in the building, it was extremely important for archive officials to implement a system that would monitor the environment, protecting their national documents from damaging factors such as temperature and humidity.
Create a SELF-SUSTAINING integrated building
Given the limited resources throughout the facility, AGN officials were seeking a building automation system that could be managed without constant human presence or interaction. Their goals were to increase overall efficiency while reducing energy costs and CO2 emissions.

MIRCOM SOLUTION

After evaluating the electromechanical installations and conducting a risk analysis, a tailored proposal was created for the AGN, which included designing the systems based on a critical infrastructure concept.

Early Detection and Warning: PRO-2000 Fire Alarm Panel

The Mircom PRO-2000 Fire Alarm Panel provides superior performance and reliability by isolating each of the Aspirating Smoke Detectors (ASD) to prevent complete system loss in the event of a short circuit in the communication loops.
Mircom partnered with Xtralis, a provider of life safety and security solutions, to develop a new interface that allows AGN officials to visualize all operational conditions and quickly determine the location of a fire in its early stages. This solution ensures business continuity with minimal disruptions while providing the necessary warning to mitigate potential disaster.

Monitoring Environmental Conditions: Building Management System with Temperature and Humidity SensorsOPENBAS-HV-WLSTH Wireless Temperature and Humidity Transmitter front

Mircom’s complete Building Management System provides integrated monitoring of the environmental conditions in each of the 72 Archive Rooms. The wireless features of the OpenBAS-HV-WLSTH and OpenBAS-HV-VAVFC allowed for a cost-effective solution to the difficult installation environment. The OpenBAS-HV-VAVFC field controllers, OpenBAS-LC-NX12R lighting controller, and OpenBAS-PM-ME11 power meter all transmit their data to the OpenBAS-HV-NX10P, which is configured as the master controller.
Mircom’s Ethernet Gateway then sends all information via multiple protocols (BACnet/IP and Modbus TCP) over IP to the 3rd party head-end software where the building management system can be monitored and controlled via a graphical user interface.
Self-Sustaining Building: Open Protocol Integrates and Future-Proofs
Mircom’s OpenBAS solution provides AGN with a self-sustaining approach to building management, automating the management of heating, ventilation, air conditioning, lighting, power metering and more. Additionally, the open protocol design gives AGN officials the flexibility to use controllers not limited to the Mircom brand. Third party solutions can be seamlessly integrated with Mircom to work in tandem by utilizing different industry standard protocols.

“Mircom’s OpenBAS solution provides AGN with a self-sustaining approach to building management, automating the management of heating, ventilation, air conditioning, lighting, power metering & more.”
