Change is the Only Constant in Life Safety

Technology advancements make our lives easier, but bring about significant changes to regulatory standards as new tech catches up to the wish lists of jurisdictions. Long standing code standards also get increased scrutiny when economic times are good and inspectors are more numerous.
This newsletter highlights both the established NFPA guidelines on emergency & exit lighting as well as developments in distributed antenna systems (DAS). With a persistently healthy economy, regulatory agencies have filled vacant positions to respond to the higher-than-average rate of building in the Portland market. This means more scrutiny of existing systems and higher standards that include technologies like DAS to aid emergency responders, but require significant capital outlay by the building developer or owner.


Most building owners and operators know inspections are required for exit and emergency lighting. However, most are unaware of how stringent those requirements are. Fewer still understand the reasoning behind those requirements.
Exit and emergency lights are required for two populations: building occupants/visitors and emergency responders, which is why they are required to work continuously for 90 minutes at full strength.
It will only take a few minutes to evacuate a building, but that lighting needs to keep working when the emergency workers are running INTO the building once they arrive.
The required testing is as follows:
  1. Monthly: 30 minute battery-only discharge
  2. Annually: 90 minute battery-only discharge
We recommend wrapping 90 minute discharge and battery load testing into your annual fire system inspections and testing as the most cost-effective solution.
As part of that process, we will provide the required documentation to have on-hand at all times per NFPA 101.

DAS Communication

We have all experienced the problem of losing wireless communication within large buildings. Emergency service communications suffer from the same difficulties. Various factors attenuate signals within buildings, resulting in communication channel losses across every bandwidth within public and private networks (concrete, low-E glass, foil-backed insulation, etc).
The FCC regulates all available spectrum in the United States and an entire industry serving "Distributed Antenna Systems (DAS)", or "Emergency Responder Radio Systems (ERRS)", has grown in recent years to address this technically challenging issue.
Essentially, these systems are a network of antennas, typically ceiling-mounted on multiple floors, connected to a common signal source that provides wireless service within a structure or geographic area.
We provide DAS design, installation, and commissioning to supply signal boosts to all bands of emergency response frequencies.
We strive to provide the best service in our industry by pricing our services fairly, delivering the highest attention to detail, and making customers for life.
