3 Must-Have Public Safety Features in a Building Connectivity System

Building owners should consider some public safety features for emergencies when installing a connection system.

Fremont  CA: Public safety communications systems are necessary for multi-dwelling apartments, stadiums, hospitals, schools, businesses, and other occupied buildings, not just for first responders. These emergency responder communication enhancement systems (ERCES) ensure that all building parts, including evacuation stairwells and passageways, elevators, and basements, are connected.

When installing a connection system, building owners should consider the following features and mandates for in-building public safety communication systems:

Multiple power options

Wattage plays an essential part in providing adequate connectivity throughout a building, depending on the size and construction of the structure. A 200,000-square-foot construction, for example, will almost certainly require a five-watt (5W) choice, although a smaller structure may only require a two-watt (2W) option. However, depending on the construction materials used, this isn't always the case. The chance of running into network design issues, pulling and rebuilding the installation, and purchasing a different product is reduced when using a dual-band product with multiple power options.

Noise figure value

The greater the RF system's performance, the lower the noise figure value. However, as more systems are installed, the noise figure is becoming a significant issue. For an average ERCES, the maximum gain is currently 95 dB with a 30 dB gain range adjustability. On the other hand, a public safety system remains dormant in the absence of an emergency until it is activated when a first responder enters the facility. More noise can interrupt radio transmission and the whole macro network, which is cause for concern. To avoid this, building owners can choose systems that produce less than 5 decibels of noise, ensuring that both commercial and public safety networks function well.

Filtering options

For ERCES deployments, either Class A or B digital filters are required, depending on the local AHJ standards. The separation of combined signals and the restoration of distorted signals are two common uses for digital filters. This is necessary to avoid excessive noise interference in the system. Building owners may not approach an AHJ first to determine whether a digital filter is necessary, resulting in the system being replaced, so it is critical to select a solution that supports both Class A and Class B to save money and time.
