Detection & Alarm System

Types of Fire Alarm Systems –

Analogue Addressable - Wired, Wireless and Hybrid Systems

For some time now, fire alarm technology has been advancing towards the analogue addressable system. This meets project requirements in which intelligence, flexibility and reliability are a pre-requisite. Analogue addressable fire detection systems provide economical installation, fire-source pinpointing, menu driven user facilities, simple plant and ancillary signalling, remote interrogation and many other facilities.

Conventional Systems

In smaller project applications, we will not 'over engineer' the solution. Where applicable, we will still employ conventional systems. A conventional fire alarm system will provide manual and fully automatic fire detection, together with the facility to raise the alarm utilising conventional fire alarm Aspirating Smoke Detection.

Aspirating Detection Systems

Providing the earliest possible warning of fire for applications of high intrinsic value, the speed and efficiency of these solutions can show an improvement in excess of 30 times that of conventional detection devices. The aspirating system's extraordinary high level of sensitivity detects microscopic evidence of fire at the pre-combustion stage, long before visible evidence of any smoke or flames is evident.

Refuge Systems

Current building regulations dictate that all new non-domestic buildings with more than one storey provide ‘refuge’ areas – relatively safe places where people who cannot easily use fire escapes and evacuation lifts can call for assistance and wait until help arrives. Simple, effective two-way communication in these areas is essential; firstly to assist rescue teams in determining where assistance is required and secondly to reassure people that help is on the way. C-TEC’s SigTEL Emergency Voice Communication (EVC) System has been specifically designed to meet the rising demand for fully compliant BS 5839 Part 9 disabled refuge systems.
