ZEI engineers code-compliant fire alarm and life safety systems from initial CAD design through fire marshal acceptance and ongoing inspection. Addressable panels, voice evacuation, mass notification, and 24/7 UL-listed monitoring meet NFPA 72 and local AHJ requirements while protecting lives and property.
Technology Partners
A representative environment where ZEI engineers, deploys, and supports fire alarm systems.
Where current systems fall short.
- Failed AHJ inspections delaying certificate of occupancy
- Aging conventional panels that cannot pinpoint the device in alarm
- Disconnected mass notification that cannot reach occupants quickly
- Inconsistent device testing leading to surprise failures during inspection
- Slow fire department dispatch from non-monitored or self-monitored systems
Comprehensive Fire Protection
From initial CAD design to final fire marshal inspection, we handle the entire lifecycle of your life safety system.
Code Compliance
Our NICET-certified engineers design systems that strictly adhere to NFPA 72, IBC, and local municipal fire codes.
Addressable Systems
Modern addressable panels tell first responders exactly which smoke detector or pull station was activated, saving critical time.
Voice Evacuation
Mass notification systems that provide clear, spoken instructions during an emergency, reducing panic and ensuring safe evacuation.
24/7 Fire Monitoring
Dedicated UL-listed fire monitoring centers dispatch the fire department immediately upon receiving a signal.
What gets installed.
A real deployment is more than the headline product. These are the components we typically specify and integrate.
Fire alarm control panel
Addressable FACP (Notifier, Silent Knight, FireLite, Edwards, Simplex) sized to the building's loop count and class.
Initiating devices
Smoke detectors (photoelectric / ionization / multi-criteria), heat detectors, manual pull stations, and duct detectors.
Notification appliances
Horn-strobes, speaker-strobes, and mini-horns sized for ADA-compliant audibility and visibility.
Voice evacuation
Networked amplifiers and speakers delivering pre-recorded and live voice messages by zone.
Monitoring communicator
IP + cellular dual-path communication to a UL 864 / NFPA-compliant central station.
Sprinkler & suppression interfaces
Waterflow, tamper, kitchen suppression, and pre-action interfaces wired into the FACP.
Survivable cabling
Fire-rated CI / 2-hour cable where required by NFPA 72 and local code.
Connects to what you already run.
Our fire alarm systems integrate with your existing identity, communication, and security systems for unified operations.
How it gets built.
Every project follows the same engineering-led sequence — designed, documented, and delivered with no surprises.
- 01
Code review & permit design
NICET-certified plans drawn to NFPA 72 and submitted to the AHJ for permit.
- 02
Rough-in
Backboxes, conduit, and wiring installed during construction phase ahead of finishes.
- 03
Device install & termination
Initiating and notification devices installed, addressed, and labeled per drawings.
- 04
Programming & pre-test
Panel programmed; every device walk-tested for activation, communication, and zone reporting.
- 05
AHJ acceptance test
Fire marshal witnesses the system test; punch list resolved before sign-off.
- 06
Monitoring & training
Central station programmed; building staff trained on silence, reset, and trouble response.
What our engineers look for.
- NICET-certified design submitted to and approved by the AHJ before any device is installed.
- Spacing and placement of detectors and notification appliances follow NFPA 72 Chapter 17 and 18 explicitly.
- System segregation: dedicated circuits, dedicated battery backup, and no shared raceway with non-fire wiring.
- Annual inspection, testing, and maintenance per NFPA 72 Chapter 14 — documented and submitted to the AHJ.
- Mass notification requirements (UFC 4-021-01 for federal, ECS for higher-ed) layered into the design where applicable.
After the install.
Service tiers built around what your facility actually needs — not a one-size-fits-all SLA.
NFPA 72-compliant annual inspection, testing, and maintenance with submitted documentation.
Higher-frequency ITM for high-rise, healthcare, and other AHJ-mandated environments.
Priority emergency response, parts coverage, and panel programming changes as the building evolves.

In-Building DAS: Meeting Fire Code Signal Strength Requirements
When a firefighter enters a burning building, their portable radio is their lifeline.
Firestopping Penetrations: The Requirement Nobody Gets Right
Of all the code requirements that affect low-voltage installations, firestopping is the one most consistently botched.
