That’s good! Just make sure you can hear it from the house.
I put up my BRK 79DCRI in the SA76RS’ case. It fits perfectly in the housing, and is a nice upgrade from the original 76RS board, because its coffin sensor is just that- Very insensitive!
The new one has the silver round sensor and the fast 5/6 BRK piezo horn of the early 80’s. When they switched to the piezo horn, it seems like the alarms got much more sensitive.
I could have put my SA76RD up, which is newer, but it sometimes falses because it is a used alarm. No way am I putting up an alarm that has seen a full life of service!
The alarm I put up was new old stock from it’s original box. Complete with a brand new battery. I might film it.
A funny bit of info: I have 2 cats that sleep in the garage at night. I had to get up on some shelves behind their bed to install the smoke alarm on a drywall encased ceiling joist, right above the frequently used outlets. There was no real perfect place to put it, but since smoke alarms are supposed to be installed on the bottom of joists in this type of construction, I did just that.
Anyways, they were pretty undisturbed while I was installing the alarm. I drove the screws in the drywall without much trouble, and secured the housing. Then I put the battery in. The alarm did not sound because it wasn’t designed to. When I was putting the cover on, the alarm beeped because the test button got caught. My cats shot out of bed and to the outside door. I laughed so hard I almost fell off the shelving. They were reluctant to get back in their beds near the smoke alarm. They kept looking up at it with wide eyes. So I gave them some cuddles and hopefully that calmed them down to where they could go to sleep. I may have just made my cats afraid of smoke alarms!
