when we do annuals we usually have an alarm guy to disable everything and he does his inspection. if we’re doing a quarterly inspection we’ll be by ourselves so we just disable the panel ourselves, we do not want the customer to be upset.
I never liked the fact that the ITV is on the riser manifold. Although its accepted means of testing some jurisdictions still want them on end of the line for a proper flush. If the system is ever drained and recharged you will also have trapped air. During an inspection it may also be possible to disable the alarms and still have the panel annunciate properly. If there are multiple risers, each flow switch should have its own zone as well as each tamper switch. If they don't, that's usually known as the cheap bid. If there is an adequate jockey pump, some occasions you can perform n inspection with the pump off. However if there is only an annual inspection the fire pump get flow capacity tested by actually flowing water out hoses and checking that it meets its design capacity under peak loads. Additionally the fire pump (electric) shall be churn tested for 10 Min on a monthly basis, Diesel Pumps- Weekly- 30 min. Sorry for rambling on but in this business you have to CYA because most building owners don't want to spend money on something they cant see.
After slowly/carefully recharging a drained system, why would the flow switch and mechanical bell continue to sound the alarm with a steady stream of water continuing to flow from that alarm drain line? Could the alarm valve flapper have failed to seat again?
Hi Jim, do you always have to ring the panel during annual inspections? I'm new so I need to learn this. An inspector is trying to initiate an annual inspection at our property but we have tenants and the date he scheduled is near Christmas 😬
