yes most RTU's have duct detectors installed, and some UL location require global shut down on all units in alarm condition.

Silence won’t kill horns or speakers

Strobes don’t make sound

@@FireAlarmFriday-shorts uh, yes it does, dependent on how it’s programmed and what the AHJ required at the time. Pressing “silence” can silence the horns/speakers but still strobe or silence horns/speakers and strobes. Again, all depends on how it’s programmed. S.O.P is to Acknowledge the alarm condition, investigate area, if no fire or false alarm, silence condition then reset. If that doesn’t work, call your service provider to extensively troubleshoot. What I’m asking here is why silence a “trouble” or “supervisory” condition since they don’t actually “alarm” the building or put the building in “alarm”. “Supervisory” and “Trouble” conditions will annunciate locally at the FACP to let certain personnel know what’s going. People will always put in service calls, regular or after hours “emergency”, and said the alarm is going off…..sure, it’s the FACP beeping or the building is actually in alarm sounding throughout? 95% of the time is the “panel is beeping”. The difference could determine whether it’s an actual emergency or some dumb jughead doesn’t understand how their equipment works that could wait for a regular service call during normal business hours.

@@FireAlarmFriday-shorts You don’t say? aren’t you a Sherlock Holmes? You sure are the piece of chalk that is needed for a dry erase board. 🤣😂

@@bjkjr1087 Strobes are silenceable in the sense that they DO or DO NOT follow the silence function on the panel. You can also send the signal to your smartwatch. kzfaq.info/get/bejne/oclgfMmG1Na-nYU.html
