Property Safety measures?.

[Abou C.]

Hello

in a 2-4 unit property what are some safety measures have you taken?. I remember somebody telling me two years ago about fire alarms being very important, and how that safe him from legal trouble when one of this tenants kids were stuck in a fire. 

1. How do one go about acquiring fire alarms into the property?, or is that for 30+ units?.

2. What other measures besides fire alarm do you add besides insurence.
