Radio Fire Alarms
A&B (Fire Prevention) Limited was a distributor, with over 10 years experience, in Radio Fire Alarms. Systems Installed Include:
Optical Smoke Detector EDA-R300
The detector operates by detecting the scatter of a pulse of infra-red light in the presence of smoke. The use of pulse techniques and sophisticated electronic circuitry provides a sensitive detector with low current consumption and ensures freedom from false alarms.
Ionisation Smoke Detector EDA-J300
Using a dual ionisation chamber incorporating less than 0.7m Ci Americium 241this detector operates by measuring the change in ionisation current caused by smoke entering the chamber. This kind of detector detects both visible and invisible smoke and is particularly suitable for protection of areas where volatile material is present.
Heat Detectors (Rate of Rise EDA-D300 & Fixed Temperature EDA-S300)
The rate of rise heat detector is a sensitive device capable of detecting small but rapid changes in temperature. The fixed temperature heat detector sense a rise in ambient temperature and operate at a pre-set value ( available at 65° C and 75° C)
Transmitter Unit EDA-T200
The unit is provided to interface other types of trigger devices such as beam detectors , air conditioning duct probes or gas extinguishing systems into the Millennium 2000 System. The interconnect wiring is monitored.
The Millennium EDA fire system is suited for all types of proposed installation, however it is most commonly specified where one or more of the following constraints occur.
Environments where the disruption caused by hard wiring is unacceptable
New buildings where the architectural requirements dictate that all cables must be hidden
Temporary installations where the system needs to be installed and removed at a moments notice.
