Oxygen Depletion Monitors for Manifold Rooms SPECIFICATION Oxygen Depletion Monitor Carbon Dioxide and Oxygen Depletion Monitor The oxygen depletion monitor is an easily installed, mains powered monitoring device. Constructed in two parts, the monitoring unit is mounted in the manifold room, and the repeater alarm is mounted outside the room to provide warning prior to entering. (Because Carbon Dioxide has specific respiratory effects in addition to oxygen depletion, a carbon dioxide accumulation monitor is required by OSHA when carbon dioxide is present and may be the cause of or contribute to oxygen depletion.) The oxygen depletion monitor provides a warning alarm at 19.5% oxygen and a danger alarm at 18% oxygen. A continuous flashing indicator assures the user the monitor is active and normal. Oxygen Depletion The Combination monitor is an easily installed, mains powered monitoring device. It is constructed in two parts: the main monitoring unit, which is mounted in the manifold room, and a repeater alarm which is mounted outside the room to provide warning prior to entering. The monitor provides for connection of up to three repeaters if the enclosure has multiple entrances. Two non-latching relays are included, set in a failsafe configuration. Calibration should be performed when first installed and then at no greater than 18 month intervals. Typical Applications • Manifold Rooms containing gases other than Oxygen and/or Air but not including CO2 or mixtures with CO2. Cryogenic and cylinder storage of gases not including CO2 or mixtures with CO2. MRI Rooms (note that the monitor may not be suitable in the MRI room itself - consult with MRI supplier). Technical Specification • Expected sensor life: 10 years Measurement techniques: Electrochemical cell Warranty: Sensor - 2 years, Electronics - 2 years Response time: 60 Seconds Alarms: Two alarm set points at 19.5% and 18% will initiate LED’s and sound on unit and at remote. The monitor provides facility for connection of up to three repeaters if the enclosure has multiple entrances. A single non-latching relay is included, set in a failsafe configuration. Calibration should be performed annually but can be performed by simple pushbutton. Typical Applications • Manifold Rooms containing gases other than Oxygen and/or Air, including CO2 or mixtures with CO2. Cryogenic and cylinder storage of gases including CO2 or mixtures with CO2. Anaerobic cabinet rooms The Combination monitor provides a CO2 alarm at 0.5 and 1.5% and an O2 alarm at 19.5%. A continuous flashing indicator assures the user the monitor is active and normal. Relays: Two alarm relays, contacts are non-latching fail-safe. Dimensions main sensor unit: 175mm wide, 110mm high and 75mm deep Technical Specification • • Sensor life: CO2 15 years; O2 2 years Sensor Type CO2: Infra Red Detector Sensor Type O2: Galvanic Electrochemical Cell Warranty: CO2 sensor 15 years; Electronics 2 years; O2 Sensor 1 year Alarms: Two alarm setpoints at 0.5 and 1.5% CO2, 19.5% O2 (other alarm setpoints available on request) will initiate LED’s and sounder on unit and at remote. Dimensions (main sensor unit): 175mm wide, 110mm High and 75mm deep Housing: IP65 rated ABS enclosure Housing: IP65 rated ABS enclosure O2 Depletion Monitor Part Number 10-yr Oxygen with 2 relays CO2/O2 Combination Depletion Monitors Part Number Carbon Dioxide and Oxygen with (1) relay (relay set for alarming CO2 level) BeaconMedæs • 1800 Overview Drive, Rock Hill, SC
