Don’t forget all the NEC code around cat 3-5, cable TV, FCC required prewire telephone for new construction, HVAC control systems, and other low voltage items like home entertainment and alarm systems.
Smoke alarms that are hardwired have some standards that a just plain fun. In our town they must have battery backup.
If you don’t have it you do not meet the min housing standards! – Now if it was only enforced. Like an HI is going to call city hall but if we put it in our report that this house does not meet min. housing standards it does wake people up.
Yes, I understand that NEC code for low voltage is outside our scope but perhaps we should revise this part. The NEC has for many years – at one time it was outside of their scope - Anyone remember when this change?
