Detection & Alarm

Conventional fire alarm systems

A conventional fire alarm system organizes detection and alarm devices into defined zones. When an alarm condition is indicated, the control panel identifies the affected zone rather than the individual initiating device.

Zone-Based Indication

The zone reports. Responders locate.

A facility is divided into defined zones, each containing its detection devices and call points. An alarm condition tells the panel which zone is affected; the response arrangement then locates the initiating device within that zone.

Zone layout, device counts and wiring arrangements are defined per project by the selected equipment and system design.

Detect

A device in a zone identifies a fire indicator.
Signal

The zone circuit signals the panel.
Control

The panel indicates the affected zone.
Alert

Warning devices alert occupants.

System architecture varies by equipment and project design.

System Components

What a conventional system is built from.

01

Control Panel

Monitors the system's zones and indicates the affected zone during an alarm condition.
02

Detection Devices

Smoke and heat detectors positioned within each defined zone.
03

Manual Call Points

Let occupants raise the alarm manually from within a zone.
04

Sounders & Visual Alarm Devices

Communicate audible and visual warning through the facility.

Application Considerations

An architecture with its own fit.

Facilities where zone-based indication supports the response arrangement
Smaller and mid-sized buildings with clearly defined areas
Institutional and commercial premises with straightforward layouts

System Types

Conventional and addressable, side by side.

Conventional

Indication: Zone-level indication: the panel identifies the affected zone.
System Organization: Detection and alarm devices are organized into defined zones.
Application Consideration: May suit facilities where zone-based indication aligns with the required system architecture.

Addressable

Indication: Individual device or programmed location indication.
System Organization: Individually identified devices communicate with the control system.
Application Consideration: May suit facilities where more specific device identification and system information are required.

Our Approach

Assess. Specify. Install. Support.

01

Assess

We begin by understanding the facility, the requirement and the protection need.
02

Specify

We identify the equipment or system appropriate to the application.
03

Install

We supply and implement the agreed solution.
04

Support

We provide servicing, maintenance and technical support where required.

Installed systems need maintenance.

Conventional systems require ongoing inspection, testing and fault support to remain service-ready. Maintenance requirements depend on the installed system, equipment and facility context — see fire system maintenance.

Conventional system questions.

What is a conventional fire alarm system?

A system that organizes detection and alarm devices into defined zones. When an alarm condition is indicated, the control panel identifies the affected zone rather than the individual initiating device.

How does a conventional fire alarm identify an alarm location?

By zone. The panel indicates which zone the alarm condition occurred in, and responders locate the initiating device within that zone.

What is the difference between conventional and addressable fire alarms?

A conventional system indicates alarms at zone level; an addressable system identifies the individual device or programmed location. Which architecture suits a facility depends on its size, layout and operational requirements.

Is zone-based indication right for your facility?

A site survey establishes the detection requirement before a system type is specified.
