Model 121 Smoke Detector
high accuracy & stability maintained over
long periodsdesigned to withstand the harshest environments
modular construction ensures simple installation& low cable requirementsrugged units, fully sealed to IP68, designed forvery high availability with minimal maintenance
requirements In confined public areas where the risk of fire isever-present, the need for adequate smoke detection is
becoming increasingly important if unnecessary loss of
life is to be avoided. Early warning of the presence of
smoke allows the maximum possible time to instigate
fire-fighting and evacuation procedures.The CODEL Model 121 measures the absorption of lighttransmitted across a fixed measurement distance, a
priciple used in CODEL’s well-proven industrial opacity
monitors. The Model 121 has been extensively tested
to withstand the unique conditions associated with
rolling stock and the high levels of vibration and shock
likely to be encountered particularly when carriages are
being shunted. These ceiling-mounted smoke
detectors are easilyinstalled and maintenance is limited to periodic cleaning
of the lenses - as little as once per year depending on
the application.CODEL smoke
detectors, together with UV flamedetectors (Models 602 and 611), have been in
successful operation in the ‘roll-on-roll-off’ trains
operated by Eurotunnel for over 15 years.
