Steps
Decide between an electric strike and an electromagnetic lock partly based on code constraints: electric strikes can typically be configured fail-safe or fail-secure, while maglocks are only available fail-safe, with no holding force when power is removed.
On a fire-rated door assembly, specify a fail-secure electric strike so the door remains positively latched during a fire; maglocks generally aren't used on fire door assemblies for this reason.
For maglocks used for access control on a means of egress, plan for the code-required release methods: free egress via a request-to-exit sensor or push button, and automatic release on fire alarm/sprinkler activation and on loss of power.
Ensure the fire alarm/maglock interconnection is wired as a supervised circuit so a wiring fault is reported as trouble rather than failing silently.
Have the completed installation reviewed against the local AHJ's interpretation of the applicable codes before commissioning, since egress-locking requirements are enforced locally.
Known gotchas
A maglock's fail-safe behavior only protects egress if the release devices are actually wired and tested correctly; don't treat 'maglocks are fail-safe' as sufficient by itself.
Never install a fail-safe electric strike where a fail-secure one is required on a fire-rated opening; the two behave oppositely on power loss and choosing wrong compromises security or fire-latching integrity.
