Assisted living fire alarms control panel

[hhsting]

I have residential home converted to assisted living for 10 people. It has basement and first floor. First floor has kitchen bedrooms, living room and basement has bedrooms.

The designer is placing fire alarms control panel. He is wiring carbon monoxide sensors, smoke detectors fire alarm control panel.

However power to the sensors are shared with light circuits. So he is extending light circuit fed from AC panelboard to the sensors.


Questions:

1. Should the carbon monoxide sensors, smoke detector sensors be dedicated circuits fed from dedicated AC panelboard per NEC 2014 Section 760 or can they be shared with light circuits?

2. Am I correct to say if shared is allowed then lights circuits AC panelboard should Not have AFCI however if it’s dedicated to sensors then those dedicated circuits for the sensors in AC panelboards should Not have AFCI?

Ok to be clear post #1 I have 4 wires smoke detectors, carbon monoxide detectors. These are detectors NOT alarms.

2 wires are for power go to the light circuit which fed thru branch circuit breaker and the other 2 wires are for communication go to fire alarm control panel.

So the above post #1 two questions can someone please have any opinion. I really appreciate your input and apologize for ignorance.

This appears to be a duplicate of another post. If you have detectors, they are not running on 120VAC. Well, you can plug them in once, but then you'll need to replace them after they burn up. There is a miscommunication between you and the designer, or he shouldn't be designing this fire alarm system.

It does appear to be a duplicate.
