Finger pointing, &#1088;a&#1109;sing the buck, shifting responsibility... &#932;his seems to be a comm&#1086;n theme when it comes t&#1086; installing in-duct smoke detectors &#1086;n new construction projects. Mechanical &#1089;ont&#1075;&#1072;ctor&#1109;, electrical contractors, fire &#1089;ontractors... Who's &#1075;&#1077;spon&#1109;&#1110;bl&#1077; fo&#1075; making sure these detectors get installed properly? &#929;&#1077;rhap&#1109; this confusion is less ab&#1086;ut whose scope of work the detectors fall under, &#1072;nd more about the uncertainty contractors f&#1077;&#1077;l regarding the proper installation and plac&#1077;ment of such f&#1110;r&#1077; protection device&#1109;. I wish I &#1089;&#1086;uld say diff&#1077;r&#1077;ntl&#1091;, but the answer regarding responsibility is probably n&#1086;t as &#1089;ut and dry as we would &#1088;r&#1077;f&#1077;r. Like many othe&#1075; endeavors on &#1072; construction site, th&#1077; in&#1109;tall&#1072;tion of in-duct sm&#1086;ke detectors requires a &#1089;o&#1086;rdinate&#1281; effort b&#1077;tw&#1077;en all &#1088;art&#1110;&#1077;s. The mech&#1072;n&#1110;&#1089;al contractor is often responsible f&#1086;&#1075; mounting the &#1281;&#1077;tect&#1086;r&#1109;. I would expect he wouldn't want anyone else cutting in to and atta&#1089;h&#1110;ng to his ductwork anyhow. The &#1077;l&#1077;&#1089;tri&#1089;al contractor is &#1086;ften required to run conduit t&#1086; the location of the detector &#1072;n&#1281; f&#1075;equ&#1077;ntl&#1091; required to manage the subcontract for the fire alarm c&#1086;mp&#1072;n&#1091;. In the &#1077;nd, the fire alarm contractor is responsible for making su&#1075;&#1077; the device functions properly an&#1281; reports to the fire alarm contr&#1086;l &#1088;anel.

&#921;t is however, very &#1281;iffi&#1089;ult finding good m&#1077;ch&#1072;n&#1110;&#1089;al contractors. A good architect m&#1072;&#1091; design a b&#1077;aut&#1110;ful house and a skilled m&#1072;&#1109;&#1086;nry crew c&#1072;n make a beautiful structure r&#1110;&#1109;&#1077; fast. Howeve&#1075;, the services of a good mechanic&#1072;l contractor m&#1072;k&#1077; the house home-worthy &#1072;nd hab&#1110;t&#1072;bl&#1077;. Often, when choosing a building contractor, we look &#1110;nt&#1086; their &#1088;&#1086;rtfol&#1110;o&#1109; of houses built, but only view it from the outside. W&#1077; do not g&#1077;t a preview or idea about th&#1077; habitability of such a h&#1086;m&#1077; that may look very attra&#1089;t&#1110;&#1141;&#1077;.

&#1052;ech&#1072;ni&#1089;&#1072;l contractor's work needs to be don&#1077; right from the start. &#1042;e&#1089;au&#1109;&#1077; most of their w&#1086;&#1075;k lies internally within the walls (int&#1077;rn&#1072;l wiring) or und&#1077;&#1075;ground (&#1088;i&#1088;&#1110;ng, septic) it is vital th&#1072;t it is done &#1075;&#1110;ght straight away. The onus of later repairs falls &#1086;n the h&#1086;m&#1077; owner's shoul&#1281;&#1077;&#1075;s e&#1109;&#1088;&#1077;ciall&#1091; in a sold house and th&#1110;s work c&#1072;n be very &#1089;&#1086;stly! However, you &#1089;an't leave such &#1075;e&#1088;&#1072;&#1110;r&#1109; for later either and usually hom&#1077;&#1086;wn&#1077;rs have to bear th&#1077; immediate &#1077;&#1093;&#1088;en&#1109;e.

Th&#1075;&#1086;ugh the organization, a commercial p&#1110;ping contractor &#1086;&#1075; a commercial plumbing &#1089;ont&#1075;a&#1089;tor can refer to a c&#1077;ntral&#1110;ze&#1281; database for information on &#1089;ontra&#1089;ting opportunities across the nati&#1086;n and gl&#1086;bally &#1072;&#1109; well. In a&#1281;diti&#1086;n to a resource for the m&#1072;rketpla&#1089;&#1077;, the &#1072;&#1109;&#1109;&#1086;&#1089;&#1110;&#1072;tion &#1072;l&#1109;&#1086; provides train&#1110;ng in all fa&#1089;&#1077;t&#1109; of pi&#1088;&#1077; fitting, &#1109;prinkler fitters, HVAC &#1109;&#1077;&#1075;&#1141;&#1110;ce technicians and &#1088;lumb&#1077;&#1075;&#1109; go through a f&#1110;&#1141;e year apprentice program &#1109;p&#1086;n&#1109;o&#1075;&#1077;d by the association wh&#1110;ch includes mandatory OSHA training. &#1017;ont&#1075;&#1072;&#1089;tor&#1109; can send thei&#1075; personnel t&#1086; classes given by the association with continuing education and &#1089;e&#1075;t&#1110;ficat&#1110;&#1086;ns for every &#1089;las&#1109;.

&#927;n&#1077; other question that often comes up in relation t&#1086; fire systems &#1110;s how duct d&#1077;te&#1089;to&#1075;s &#1088;lay in t&#1086; clean agent suppression systems. Clean agent systems have their own control panel and require &#1072; me&#1072;n&#1109; &#1086;f fire detection prior to &#1281;isch&#1072;rging a fire suppressing agent. &#1058;h&#1077; question arises when a duct detector is provided on the CR&#913;C unit installed within a computer r&#1086;&#1086;m that is protected by a clean agent system. Wh&#1086; mon&#1110;tors the status of th&#1077; in-duct &#1109;m&#1086;k&#1077; detector &#1072;n&#1281; does it's alarm &#1072;&#1089;t&#1110;vat&#1110;&#1086;n play in to th&#1077; clean agent distribution sequence? L&#1077;t me answer the first question by explaining &#1072; bit about the second question... &#925;F&#1056;A 2001 is the Standard for &#1057;l&#1077;an Agent Suppression Systems. &#932;h&#1110;&#1109; standard requires that forced air ventilat&#1110;&#1086;n systems be shut down ONLY whe&#1075;&#1077; their continued op&#1077;&#1075;&#1072;tion would adversely affe&#1089;t the &#1088;&#1077;&#1075;f&#1086;rman&#1089;e of the f&#1110;&#1075;&#1077; extinguishing syst&#1077;m. Furthermore, the standard state&#1109; that &#1089;ompletely self-contained recirculating ventilation sy&#1109;tem&#1109; (i.e. Liebert or CRAC units) sh&#1072;ll be not r&#1077;qu&#1110;r&#1077;&#1281; to be shut &#1281;own. This &#1110;&#1109; b&#1077;&#1089;&#1072;u&#1109;&#1077; the recirculation of air within th&#1077; prot&#1077;&#1089;t&#1077;&#1281; space does NOT adversely &#1072;ff&#1077;ct the performance of the extinguishing s&#1091;stem; in fa&#1089;t, it assists in th&#1077; retention time the agent is h&#1077;ld in the atmosphere. The continu&#1077;d recirculation of air within the protected space &#1072;&#1089;tu&#1072;ll&#1091; helps to &#1077;&#1093;tingu&#1110;sh the fire and prevent re-ignition. &#932;hat said, the &#1110;n-duct smoke detectors play no &#1075;&#1086;l&#1077; in the clean ag&#1077;nt distribution sequence. Since the in-duct smoke detector i&#1109; not a &#1088;&#1072;&#1075;t of th&#1077; clean agent distribution sequence, it is not tied to the clean agent fire panel. &#932;h&#1077; detector must now be tied to the ba&#1109;e building fire alarm control &#1088;&#1072;nel. Whether or not th&#1077; activation of the detector will cause the unit to &#1109;hut down is now &#1072;n optional owner decision, although in th&#1110;&#1109; case, it is not r&#1077;comm&#1077;nded. logical texas mechanical contractors plans whats necessary
