Senator 25

The Senator 25 is designed to provide very high sensitivity smoke detection in a small package.

ClassiFire Perceptive Artificial Intelligence ensures that the detector operates at optimum sensitivity for the protected environment, without the need for complex setup. This means the product will configure itself to provide high sensitivity in a computer room or reduced sensitivity in a smoky area.

The detector is designed to fit into a Docking Station. All sampling pipes and cables are connected to the Docking Station as a first fix operation leaving the detector to be fitted during the final commissioning phase if required. This ensures that detectors are less likely to be damaged during the installation.

Upgradable volt-free Fire and Fault relay outputs are available for remote monitoring by local fire detection or BMS systems.

Ultra small low cost aspirating smoke detector for easy and discreet installation
High sensitivity provided by laser based forward light scatter for reliable early warning
Single sampling pipe up to 50m in length (still air)
Unique ClassiFire^® Perceptive Artificial Intelligence system that dynamically adjusts the detector’s operating parameters, allowing for day to day changes in the protected environment and dust separation system contamination
Unwanted alarms from dust are avoided using patented Dual Technology LDD 3D3 Laser Dust Discrimination and elimination system
RS485 communications built in as standard for networking and remote communications
