5 1 INTRODUCTION These instructions cover mounting and wiring of replacement or additional Series 1650 or 1660 Gas Detector sensors, and replacement of a gas sensor element. Affected sensors are BM-5409 (chlorine) and BM-5410 (sulfur dioxide). See Instruction Manual for further information about Series' 1650 or 1660 Gas Detectors. 1.1 Mounting (See to Figure 1) Locate sensor module approximately 12" to 36" (305 mm to 915 mm) from the floor. NOTE : The sensor module may need to be raised if there is constant gas present Position the module with sensor element and cable fitting(s) pointed downward to prevent water entering the enclosure through the fitting(s), resulting in erratic operation Secure the module to the wall with two (2) #8 screws. NOTE: The inside of the module enclosure is sprayed with a copper conductive coating for protection against radio frequency interference (RFI). 1.2 Electrical Connections Refer to Series 1650/1660 Instruction Manual for interconnection diagrams and figures showing location of wiring terminals. WARNING: TURN OFF ALL POWER BEFORE WIRING SENSORS CAUTION: MAXIMUM ALLOWABLE CABLE LENGTH IS 1,000 FEET (305 METERS) NOTE: FOR OUTDOOR LOCATIONS, APPLY SILICON SEALANT TO CABLE CLAMP(S) Figure 1 - Sensor Mounting Dimensions Series 1650/1660 Gas Detector

CAUTION: INCOMPLETE TIGHTENING OF CABLE CLAMP OR COVER SCREWS CAN ALLOW WATER TO ENTER SENSOR RESULTING IN ERRATIC OPERATION l. Test gas detector operation using Capital Controls Gas Sensor Test Kit, BM-4709 or a convenient source of gas Series 1660 Multipoint Gas Detector Sensor Wiring-Series Connection (See Figure 2) NOTE: Any combination of gas sensor types may be wired in series, and in any order a. Wire sensor using shielded, 3-conductor cable not smaller than 18 gauge. b. If replacing or adding a sensor within a string of sensors, loosen four (4) captive screws and remove covers of two adjoining sensors and additional or replacement sensor to access wiring terminals. c. Remove sensor hole plug and install second cable clamp. d. Use existing cables if replacing a sensor, or add cables when adding an additional sensor. Insert cables from adjoining sensor though cable clamp of new/replacement sensor and strip ends of each of the three (3) wires at the end of each cable. If replacing or adding a sensor to the end of a string of sensors, continue to Step j or k. NOTE: Field wiring terminals are located on smaller of two circuit boards. Use both terminal blocks provided to wire sensor Series 1650/1660 Gas Detector

7 e. Connect terminal + of each existing sensor to separate field wiring terminal + of new/replacement sensor. f. Connect terminal G of each existing sensor to separate field wiring terminal G of new/replacement sensor. g.

Test gas detector operation using Capital Controls Gas Sensor Test Kit, BM-4709 or a convenient source of gas. 1.3 Sensor Element Replacement (See Figure 3) WARNING: USE ONLY CAPITAL CONTROLS SENSOR ELEMENT OR THE WRRANTY IS VOID. INCORRECT OPERATION WILL RESULT IF ANOTHER SENSOR IS USED. WARNING: SENSOR ELEMENTS CONTAIN ACID. DO NOT DISASSEMBLE. DO NOT INCINERATE SINCE SENSOR IS SEALED AND COULD EXPLODE. NOTE : If any moisture appears on the sensor element, protect your hands with gloves and wipe away the moisture with a clean, dry cloth. If any acid contacts your hands or other parts of your body, wash with soap and water. If acid has come in contact with any printed circuit boards, replace the printed circuit boards Turn OFF power at the receiver Loosen the four (4) screws and remove the cover on the sensor module Remove the three (3) screws holding the snesor element assembly and the printed circuit board in the sensor module.
