I’m at the hotel with my mom because we’re visiting Phillidelphia for Memorial Day Weekend. According to the maintenance guy (that fixed a switch in our room went haywire), the hotel is a little less than five years old. Could the hotel get in trouble for this, or would it be the alarm company’s fault?
The code and strobe application guides reference non-sleeping areas and sleeping areas. The sleeping area strobe intensity is based on what it takes to wake a person up. The illustrations below are from this application guide.
Difficult to say. If it’s a non-ADA room, the strobe isn’t required. So if it isn’t required but it is there, is it required to be up to the standard?
One scenario could be that the AHJ wanted strobes in every room. Hotels have a lot of rooms! And when you figure on one of those EG4’s the current load is 4X greater on 110Cd vs 15Cd, there could have been a trade off where the candela was allowed to be lowered in the non-ADA rooms to save on putting in multiple booster panels. In other words, you would have to know what the system was designed for to determine if there is a violation. All designs are approved by the AHJ.
As far as the 1/4 watt setting on the speaker… The city of Philadelphia requires 75dba in sleeping rooms at the pillow for systems installed after Jan 2010 - 70dba for systems installed prior. So as long as it was tested at 75dba, the speaker can be tapped at whatever wattage it needs.
Off topic but another thing to look out for when your traveling around the city of brotherly love - all manual pull stations have to have a sign installed above them that says “In case of fire - sound alarm and call 911 or fire department”. See how many you can find missing!
I’ve done some work in philly in the past year or so, they generally know exactly what they want.
non-hearing impaired rooms don’t require any strobes and the ones that have them only need 110cd in the sleeping areas and 15cd in all other areas. I’d be surprised if the strobes even went off when the alarm was activated unless the smoke in that specific room set it off.
