Daily Discussion question submitted from a member:
It seems that I must have missed something in the 23 years I've been in Code Enforcement. Since when has it been required for a smoke detector to be in the pit of the elevator? This is absolutely insane. We've had more nuisance alarms recently in new buildings. One is a 4 story nursing home, that the alarm has gone off 4 times. The alarm company changed the detector and it been good now. However there is still dirt, moisture, humidity, etc. All the things that smoke detectors don’t like.
I've looked and Googled it and have only come up with a heat detector within 24" of the sprinkler head, which I understand. I know smoke rises so why isn't the top of the shaft sufficient? I feel we are going backwards.
