Firesens wireless fire alarm family: control panel with map display, siren, gateway, smoke/heat detector and two call points

Overview

The problem in the field. In operating factories, heritage buildings, large warehouses and open sites, running a wired fire detection loop halts production, damages the structure and is expensive. Standard conventional/addressable panels raise the alarm, but site-specific actions (lock a door, shut off ventilation, trigger a specific extinguisher) require an extra PLC and more cabling. In solvent, paint and dusty environments, a single type of detector produces false alarms or reacts too late.

The solution. Firesens connects battery-powered or 24 V wireless end devices (smoke/heat sensors, buttons, sirens, relay output units) to the gateway and panel over LoRa 433 MHz. The panel, PC application and map HMI show every device with its location, battery, temperature and signal strength; on alarm, siren, door and extinguisher outputs are triggered according to the scenario. Thanks to two-way communication, the panel sends commands and each device acknowledges them. Installation is carried out in the running plant without stopping production.

For sites with special requirements. Firesens is not a replacement for a legally mandated fire detection system; it is positioned as an additional, special-purpose protection layer for industrial sites and sites with special requirements, and is evaluated project by project. The smoke/heat sensor is EN 54-7 self-declared; EN 54-25 (wireless components) certification is planned. The roadmap covers early warning based on threshold and trend analysis across several sensor types (optical smoke, temperature, rate-of-rise, gas), BMS/SCADA integration over Modbus TCP, and a new version of mobile notifications.

Features

  • Linked door control: locks/unlocks doors and monitors door status according to the alarm scenario (relay unit + magnetic contact).
  • Extinguisher triggering: triggers the site's own extinguishing unit (gas, foam, sprinkler pre-control) based on sensor data, with double confirmation and a delay.
  • Map-based HMI: device status on the site plan on a 7-inch display; the same view in the PC application.
  • Device health reports: battery, temperature and RSSI from every device.
  • Two-way communication with acknowledgment: each device acknowledges panel commands (ACK).
  • Dry-contact integration: the relay unit connects to a zone input of an existing panel.
  • Multilingual panel: Turkish / English interface.
  • TargetMulti-sensor fusion and early warning: cross-checking data from different sensor types, trend analysis (rate of temperature rise, smoke density), a pre-alarm level.
  • TargetExtinguishing control logic: double-confirmation and delay logic modeled on the EN 12094-1 approach; certification is not in scope.
  • TargetBMS/SCADA integration: Modbus TCP.
  • TargetMobile app / notifications: a new version of alarm and fault notifications.
  • TargetOptional modules: gas sensor node, outdoor siren, 4G backup link, cloud monitoring (Telemetry & Process Intelligence), portable notification unit (WR-001 LoRa Wireless Alarm / Call Remote), repeater.

Applications

  • Paint, solvent and chemical plants
  • Wood and textile production
  • Logistics warehouses
  • Heritage buildings and museums
  • Hospital, dormitory and hotel annexes
  • Energy and infrastructure sites
  • Temporary and construction-site installations

Positioning. Firesens does not replace a legally mandated fire detection system; it is evaluated project by project as an additional, special-purpose protection layer. It can be connected to an existing wired panel through a dry contact on the relay unit.

Ex zones. Firesens is not ATEX/Ex rated. In solvent and paint facilities, Ex zone assessment is the customer's responsibility.

Installation and service. Battery replacement and system expansion are carried out by Elmes or an authorized installer; manufacturing and service are based in Ankara.

Compliance & documentation

The smoke/heat sensor carries a manufacturer's self-declaration for EN 54-7; there is no accredited test report or EN 54-25 certificate yet. Firesens is offered as an additional, special-purpose protection layer, not as a replacement for legally mandated fire detection. EN 54-25 requirements (link supervision, backup channel, battery monitoring) are being built into the new series design.

Frequently asked questions

Is it a certified fire alarm system?

The smoke/heat sensor is EN 54-7 self-declared; there is no EN 54-25 (wireless components) certificate yet, and it is planned. Firesens is positioned as an additional, special-purpose protection layer rather than a legally mandated fire detection system, and is evaluated project by project.

Will it interfere with another system in the same plant or a neighboring site?

Every network has its own ID; packets with a different ID are ignored. The new series targets at least 8 independent networks through channel and network-ID combinations.

What happens when an end device's battery runs low?

The device reports a low-battery flag and the panel raises a warning; the device keeps detecting. If its reports stop, the panel raises a “missing device” fault.

Can it be integrated with an existing wired panel?

Yes: the relay unit connects to a zone input of the existing panel through a dry contact. BMS/SCADA integration over Modbus TCP is planned.

How can the range be extended?

Mount the gateway antenna high and outdoors, and use more than one gateway on large sites. An extra hop through repeaters is planned.

How are doors or extinguishers controlled?

The relay output unit is assigned to a scenario; once the alarm is confirmed, the panel sends the command and the unit acknowledges it.

Are mobile notifications and a site map available?

A map-based HMI is available (7-inch display and PC application). A new version of mobile notifications is planned.

Can it be used in ATEX/Ex zones?

No, Firesens is not ATEX/Ex rated. In solvent and paint facilities, Ex zone assessment is the customer's responsibility.

What about warranty and service?

2-year warranty; manufacturing and service in Ankara. Battery replacement and expansion are carried out by Elmes or an authorized installer.
