Technical Specifications

Approvals/certifications Certified to EN54-5, 7 & 17 by the LPCB.
Compatibility Compatible with C-TEC's HP508 Hush-Pro Controller.
Type Multi-Sensor (Heat assisted optical 0.2dB/m + A2 heat).
Application/operation As well as operating independently, the CA414’s smoke & heat sensors combine to produce a sensitive response to freely burning fires, e.g. when a rise in heat is detected, its smoke response level reduces for improved detection and reduced false alarms.
Application temperature 25°C typical, 50°C max.
Static response temperature 54°C min, 65°C max.
Sensitivity 0.2dB/m optical; A2 heat.
Supply wiring 2-wire monitored, polarity sensitive.
Supply/operating voltage 27 to 40V DC.
Quiescent current 370uA - 5mA @ 24V.
Alarm current 6mA (LEDs illuminated).
Indicators 2 LED indicator strips emitting red light when in alarm offering 360º visibility. Optional remote LED.
Connections Via HP408 base: 1 +Ve IN (analogue swich); 2 +Ve OUT (analogue switch); 3 Remote LED +Ve; 4 0V; 5 0V; 6 Screen; 7 Screen.
Expansion connections Remote LED output available via HP408 or 408R base. Current source to the negative line, short-circuit protected. Max voltage 2.7V DC.
Product dimensions (mm) 102.2mm diameter x 37mm deep (detector in base); 102.2mm diameter x 57.5mm deep.
