It might be less expensive but most of the time the cheap systems work out costing much more than getting it done right by a UL listed company.
You can use Maglocks (no moving parts) or you can use strikes( moving parts which wear out in 3-5 years on certain brands) If you use strikes that allow free egress then often you don’t have to have a request to exit motion or buttons to get out like you would with a maglock. Often the fire marshal will require that the fire alarm release the doors even with strikes so you can not only get out but so fire and emergency workers can get in.
DSX, DMP, Honeywell, Bosch and other products are used and with electronic locks you don’t need to re-key your building after someone leaves. Request to exit motions and a tie into the fire alarm system make it so people can get out in an emergency. Maglocks require door release with a button, motion and often a connection to the fire alarm panel.
Access Control systems will allow you to set user groups and limit access to certain days and certain hours so managers can get into the building any time but normal daily workers badges will only work 9-5PM as an example.
