FIRE DETECTION

Fire Detection Systems Design

We develop detector, siren, and panel electronics for conventional and addressable fire detection systems. We provide end-to-end engineering support from concept to production-ready hardware architecture.

Fire detection systems are critical safety products requiring reliability, fault tolerance, and low power consumption. HEFA Teknoloji provides R&D partnership to manufacturers throughout the fire detection device development process.

Safety-Focused Engineering Approach in Fire Detection Systems

Fire detection systems are safety-critical systems where the detector, panel, and field wiring must work together. For this reason, the design process considers not only sensor performance but also system topology and line behaviour.

Our approach in every project is based on the following principles:

  • Measurement reliability and stable alarm algorithm design on the detector side
  • Multi-zone architecture, fault monitoring, and event management infrastructure on the panel side
  • System-level analysis of conventional and addressable line topology
  • Scenario-based validation of detector–panel interaction
  • Safe management of open circuits, short circuits, and device failures
  • Fail-safe alarm and fault behaviour design
  • Low standby current and long-term field stability
  • Sustainable hardware architecture suitable for series production

In fire detection products, the goal is not just a working detector or panel — but an integrated system that behaves predictably, consistently, and safely under field conditions.

Frequently Asked Questions

Do you develop both conventional and addressable fire detection systems?
Yes. We develop detector, siren, and panel electronics for both conventional (zone-based) and addressable fire detection systems. This includes 1–8 zone conventional panels and addressable panel communication infrastructure.
What types of fire detectors do you design?
We design optical scatter-based smoke detectors (IR and dual-wavelength architectures), fixed temperature and rate-of-rise heat detectors, and combined smoke + heat detectors. We cover analog measurement board development, TIA circuit design, and signal processing architecture.
How do you approach fail-safe design in fire detection systems?
Fail-safe design is a core requirement in fire detection. We perform fault scenario analysis including open circuit, short circuit, and sensor failure conditions. Power consumption is optimised and long-term field stability is considered in every design.
Can you develop PC software for fire panel service and maintenance?
Yes. We develop PC software for fire panel service and maintenance interfaces, including RS485 and USB service connections. This allows field engineers to configure, test, and maintain panels from a connected computer.
Do you support the full development cycle from concept to production?
Yes. We provide end-to-end engineering support — from concept, sensor selection, and circuit design through to prototype production, validation, and production-ready design transfer.
