Open-Area Smoke Imaging Detection (OSID)

The linear smoke detector OSID using dual wavelength detects only repeatable absolute smoke obscuration values, while rejecting the presence of dust particles or solid intruding objects. This is already provided using the simplest configuration – one imager and one emitter.
One imager can work with up to seven emitters.
An optical imaging array in the OSID detector provides a wider viewing angle to locate and capture images. Consequently, the system is easier to install and align and can compensate for drift caused by natural shifts in building structures.

In addition, OSID requires only limited space (15 - 20 cm) in ist line of view. Therefore, the solution can be deployed safely between ceilings and supporting structures, moving cranes, etc.

Each component can be mounted directly to the surface or can be secured with the supplied mounting brackets.

OSID-DE (Dual Ended)

Next to this step-in model, there is OSID-DE (Dual ended) that uses a similar CMOS sensor with wired or battery-powered emitter(s) roughly aligned on the opposite wall within the protected area. The emitter sends both infrared and ultraviolet coded light signals to the imager. The innovative use of dual light frequencies in an open-path device enables OSID-DE to discriminate between real smoke and other solid objects. It offers a high resistance to sudden and transient dust and steam clouds, thus drastically reducing false alarms.

OSID-R (Reflective)

In its simplest configuration, OSID-R (Reflective) uses an imager and a reflector. It operates on the principle of light obscuration utilizing an Infra-Red beam and smart analysis on pixel level of its reflector offering superior performance. Power and connectivity occur in the imager only and the OSID-R only requires a single standard reflector on the opposite wall (and not a larger reflector the further the distance).
