NFPA 731, Section 5.1.6 is all about the proper function of entry and exit delay features in a security system to reduce the likelihood of false alarms. Annex A, Section A.5.1.6.2 in the back of NFPA 731 states the following:

“A.5.1.6.2 The mechanism, such as a keypad or other human/ machine interface (HMI), is to be located no farther than a normal 15-second walk from the point of entry. Depending on the size of the premises, the mechanism can be opposite the point of entry, in the next room, or even the same room. This provision is in this standard so that compliance with ANSI/SIA CP-01, Control Panel Standard — Features for False Alarm Reduction, can be achieved”.
