TM 10-6665-297-13&P2-7WARNINGANDALARMMODIFICATIONS (continued)and circuitry for the manual resetting of warning and alarm circuit relays that have been energized inresponse to emergency gas conditions or tests. Further, WARN or ALARM light circuits operate to turnon the lights in response to emergency conditions whether the relay will operate or not. These modesof operation assure that attention will be directed to the exact location of an emergency condition andthat a visual indication of an emergency will appear on the module front panel even if a warning oralarm delay should fail.For installations where other modes of operation have special advantages, on-site modification ofcontrol module circuitry can provide the following optional modes:-Manual resetting of warning and alarm relays by means of one switch common to several modules.-Automatic resetting for both warning and alarm relays.-Automatic resetting for either warning or alarm relays.-Warning and alarm relays not energized during TEST (to prevent activation of external devices such assprinkler systems, process control mechanisms, etc.Instructions for each of the above modifications appear in the following paragraphs. (Refer to Figures2-26, 2-27, and 2-28.)2-7.1MODIFICATIONFORCOMMONPOINTRESETTINGOFCD830MODULES :To modify warning andalarm circuits of two or more CD830 modules for manual resetting from a common point:1.Remove each module from enclosure or housing. CD80OOW and CD802W: unlatch and swingfront panel to open position.2.Using small wire cutters, cut white/gray wire connected to pin 1 of CD800/830 alarm light socket orwhite/black wire at pin 2 of CD802/832 alarm light socket. Tape cut end of wire to avoid shortcircuits.3.Grasp red ALARM/RESET lens with fingers and pull to extract from module front panel.23-96175/15/782-39
