Siemens OOHC740 fire and CO detector for very early and reliable detection of emerging fire, due to analysis of the three criteria smoke, heat and gas.
Fast response to all carbon monoxide (CO) generating fires and very early and reliable alarming in environments with deceptive phenomena. Works according to the scattered-light principle with two sensors, optical forward and backward scattering. Opto-electronic sampling chamber blocks disturbing extraneous light but optimally detects both dark and light smoke particles.
Two additional heat sensors and an additional CO sensor increase the fire detector’s immunity to deceptive phenomena and the response characteristics of the fire detector.
Selectable detection behaviour by application-specific ASA parameter sets. The additional CO analysis makes it exceptionally fast and ideal for applications where the occupants make speed of detection critical (e.g. nursing homes, hospitals, sheltered accommodations, etc.). Additional detection channels for CO life safety detection and CO or thermal ambient condition monitoring.
The base must be ordered separately.
| Key Features |
|---|
| > Multi-sensor fire detector consisting of: > Point detector > Detector dust cap to protect the point detector during the construction phase > Functions according to the scattered light principle with two sensors, optical forward and backward scattering > Opto-electronic measuring chamber that obstructs disruptive extraneous light but provides excellent detection of both light and dark smoke particles > Two additional heat sensors and an additional CO sensor increase the point detector's response behaviour and immunity to deceptive phenomena > Technical message, ambient supervision: Technical message if the temperature or CO concentration exceeds/falls below the preset limits > Functions using an electro-chemical CO cell > CO concentration alarm is transmitted to an independent technical CO alarm channel > Independent processing of the CO signal for the CO alarm channel and CO signal for fire detection > Selectable detection behaviour of the CO alarm channel, regardless of ASA parameter sets for fire detection > Selectable detection behaviour thanks to application-specific ASA parameter sets > For early detection of smouldering fires that generate CO (e.g., mattress fires in homes) > Areas with increased CO exposure, e.g., heating rooms, combustion plants, fermentation plants, garages, automotive workshops, animal stalls, chemical laboratories, or production sites > For reliable fire detection in an environment with deceptive phenomena > Can be used addressed |
