"I am planning to design a alarm control panel for my house."

Is this just a "private" hobby project, or are you trying to develop a product?

For a commercial product, you not only have to comply with all the normal PSTN attachment requirements (which still apply to a hobby project), but there may also be specific national and/or regional requirements imposed by legislators, insurers, police, etc, etc,...
eg, see http://www.redcare.bt.com/security/...s/acpo.htm for some implications of recent British Police policy in the UK market.
