Product Discontinued

This product has now been discontinued and has been replaced by VESDA-E VEP and VESDA-E VEU Aspirating Smoke Detectors.

Please note: spares for EF-FT1 Aspirating Smoke Detectors are still available and part numbers can be found below.


The EF-FT1 detector is an air-sampling system with an alarm sensitivity range from 0.001% to 20% obscuration/m. This detector is classified as a Very Early Warning Smoke Detector and can reliably detect fire at an early stage at low to high concentrations of smoke over an area of up to 2,000m2.

The detector is configurable for a variety of environments, providing an ideal fire detection solution for power stations, telecommunications and IT facilities, clean rooms, warehouses, cold storage, harsh and hazardous areas, and museums.

How it Works

The FT1 detector draws a combined air sample holes into its 4-way inlet manifold from a pipe network, then filters and analyses the sample in a laser detection chamber. Alarm states (Alert, Action, Fire 1, Fire 2) are shown on the display and communicated to a host fire alarm control panel after a pre-programmed time delay.

Product Features

Programming and Configuration

The four alarm sensitivity thresholds and delays can be individually programmed. The FT1 detector provides a simple and comprehensive display that includes an LED array to show the measured smoke level for the currently selected pipe, and an on-board programmer for local configuration.

RS485 interfaces allow connections to programming devices and remote displays, and the TCP/IP Ethernet interface can provide access to an email messaging service.

Inputs and Outputs

There are 5 relays as standard and the system can be expanded with an optional module to provide additional 4 to 20mA analogue outputs.

Aspiration and Flow Sensing

The aspirator is a 2000 Pa, high pressure and high volume fan, which provides superior detection times over long pipe lengths and reliable detection in high air-flow environments. Airflow in each pipe is monitored by a dual element thermal sensing system, with airflow faults indicated on the display and monitoring equipment.
