The OSI-RIE-34 is an analogue addressable reflected beam smoke detector. The detector transmits a beam of infra-red light toward a reflector up to 100 metres from the transmitter-receiver. The beam is reflected back to the transmitter-receiver where the in-coming signal is analysed. If the beam is obscured by smoke, the detector initiates a fire alarm.

The OSI-RIE-34 transmitter-receiver connects to an analogue addressable circuit on a Pertronic F220 or F100A fire panel. The reflector requires no cabling unless it is fitted with the optional anti-condensation heater.

Alignment

The infrared transmitter and imager (receiver) are mounted in a lens assembly (“eyeball”) that can move 20° vertically and 50° horizontally. The transmitter-receiver has four coloured arrows which are visible when the cover is removed. These arrows light up during the alignment process, guiding the user to manually align the lense assembly.

Features

• Combined transmitter-receiver unit with 12° field of view
• Operates over a distance of 5 to 100 metres between transmitter-receiver and reflector
• Analogue addressable communication
• Compatible with Pertronic F220 and F100A fire panel AA circuits
• Rotary address switches
• Simple and intuitive beam alignment procedure
• Automatically sets the alarm threshold
• Tolerates up to ± 1° movement of mounting locations
• Resistant to strong light sources; does not alarm when saturated by sunlight
• Complete blockage of the beam initiates a fault signal
• Beam adjustment range: ± 50° horizontal and ± 20° vertical
• Transmitter-receiver has a built-in anti-condensation lense heater
• Remote test station available for simulated smoke test from ground level
• Standby, fault and alarm LED indicators visible from the front and bottom
• Automatic drift compensation
• Colour: White
• Paintable cover (see note)
• Plug-in terminal blocks, 2 mm²
• Optional anti-condensation heater kit available for the reflector
• Powered from the analogue addressable loop
• Independently tested and SAI Global StandardsMark certified to AS 7240.12:2018

NOTES: DO NOT paint the main housing or eyeball. Only the removable cover is paintable.

The transmitter-receiver's integral lens heater cannot be powered from the analogue addressable circuit. The heater requires an external 24 V dc (nominal) power supply capable of supplying at least 0.5 amp.
