Xtralis VESDA OSID-EHE — environmental housing for an OSID emitter, the transmitting half of an open-area smoke imaging detection pair.
An OSID system pairs an imager with one or more emitters across the protected volume; the emitter projects the UV and infrared beams the imager reads. OSID-EHE is the emitter enclosure. OSID-EHI, the imager enclosure, is built differently: it adds cable glands, an entry for the OSP-001 FTDI service cable and a second window so the alarm and fault LEDs stay visible from below. The glazed ABS housing passes the beams with minimal attenuation and suits both battery-powered and 24 V wired emitters.
- IP66 and NEMA 4/4X against dust and water ingress
- ABS, grey RAL 7035, IK07 external mechanical resistance
- 241 × 194 × 127 mm (9.64 × 7.76 × 5.08 in.)
- Usage temperature -25°C to +60°C (-13°F to 140°F)
- Three pre-drilled screw fixings; housed systems are 1-on-1 only
This is an empty enclosure: no emitter, no imager, no heater. Where condensation is expected Xtralis says a heater of at least 5 W can be fitted inside. Order OSID-EHI if the unit being weatherproofed is the imager — the two are not interchangeable.
