1. Sentek INTRODUCTION sentek s Carbon Monoxide Detector is effective for detecting any buildup of carbon monoxide also known as CO gas in your home or office The features of your CO gas detector includes 1 Easy to install It allows connecting to fire control panel or security monitoring system 2 Monitoring for carbon monoxide in a continuous manner 3 Giving a loud alarm 85 dB when it detects a buildup of carbon monoxide 4 Self testing its operative functions continuously 5 Offering a 5 year warranty for the carbon monoxide sensing unit YOU SHOULD KNOW ABOUT CARBON MONOXIDE Carbon monoxide also known as CO by the chemical form is considered to be a highly dangerous poisonous gas because it is colorless odorless or tasteless and very toxic In general biochemistry phenomena have shown that the presence of CO gas inhibits the blood s capacity to transport oxygen throughout the body which can eventually lead to brain damage In any enclosed space home office recreational vehicle or boat even a small accumulation of CO gas can be quite dangerous Although many products of combustion can cause discomfort and adverse health effects it is CO gas which presents the greatest threat to life Carbon monoxide is produced by the incomplete combustion of fuels such as natural gas propane heating oil kerosene coal charcoal gasoline or wood The incomplete combustion of fuel can occur in any device whic2. arranty is expired Sentek Sentek Electronics Co Ltd

6. ossible situations please refer to the list of sources of carbon monoxide in page 1 CAUTION This detector will only indicate the presence of CO gas at the sensor However you have to be aware that the CO gas may be present in other areas in the premises ACTIONS TO TAKE AFTER THE PROBLEM BEING CORRECTED Once the problem about the CO gas presence in the premises has been corrected the alarm of the detector should be off After waiting for 10 minutes push the Test button to test the detector so that you can make sure that the detector is working properly again SPECIFICATION Operating Voltage 12Vdc or24Vdc 100ppm within 90 minutes Sensitivity 200ppm within 35 minutes 400ppm within 15 minutes Alarm Sounds 85dB Operating Temp C 0 C 40 C Output Voltage With Relay Output Dry connection output WARNING AND LIMITATION Note that GD 530 series gas detector is not supposed to be used as smoke detector or fire alarm In addition this detector should not be installed in a danger area as defined by National Electrical Code A gas detector will operate normally under regular power supply therefore it will not perform at any situation when power outage occurs WARRANTY INFORMATION Under the normal operation conditions the manufacturer provides five year warranty for the sensor head of gas detector and one year warranty for other parts for repairing without charge Part and labor charge will be required after the w
7. sible to sleeping areas of the home The human body is most vulnerable to the effects of CO gas during sleeping hours For maximum protection a CO detector should be located outside primary sleeping areas or on each level of your home In the figure below are suggested locations in the home The electronic sensor detects carbon monoxide measures the concentration and sounds a loud alarm before a potentially harmful level is reached a BEDROOM GROUND FLOOR Zz ive leg J Ge Q O z CARBON MONOXIDE DETECTOR Do not place the detector in the following areas a Where the temperature may drop below 40 F 4 49C or exceed 1000F 37 8 C b Near paint thinner fumes Within 5 feet 1 5 meter of open flame appliances such as furnaces stoves and fireplaces In exhaust streams from gas engines vents flues or chimneys Do not place in close proximity to an automobile exhaust pipe this will damage the detector WIRING DIAGRAM FOR NB 983 SERIES CARBON MONOXIDE DETECTORS Figure 2 shows the wiring diagram for NB 983 series carbon monoxide detectors ee oF LAST DETECTOR BASE FIRST DETECTOR BASE ADIAAG AO GNA INSTALLING THE BASE OF DETECTOR 1 All the wires in the base compartment should be flattened and are not touched to any connectors to ensure that the detector head be smoothly fastened to the base 2 When using the jump wires to check the connectivity for each gas detector in the circ
