ALOA ICRL study guide
ALOA ICRL · Work through your exam, one topic at a time.
The ICRL is an institutional locksmithing and security-hardware credential. It is intended for technicians and facility security staff who install, service and administer locking hardware in institutional settings - schools, hospitals, government buildings, campuses and multi-tenant facilities - rather than in purely residential or automotive work. The exam blueprint is organized into four equally weighted domains: institutional door hardware and locking devices; master keying and key control systems; electrified hardware, access control and the life-safety interface; and codes, standards, specifications and facility security administration. Questions are multiple choice. The ALOA ICRL study guide has 4 sections and about 1,211 words.
01Institutional Door Hardware and Locking Devices
An institutional door is a system: frame, hinge, lock or latch, closer, exit device, coordinator, stops, and seals must work together. Candidates should know ANSI/BHMA A156 grade levels (Grade 1 heavy commercial, Grade 2 standard commercial, Grade 3 light commercial) and that grade is a durability test rating, not a fire rating or a security rating.

Master keying is both a mathematical system and an administrative program. A change key operates one lock; a master key operates a group; a grand master operates several masters; a great grand master operates all.

Electrified hardware is designed around what happens when power fails. Fail safe means unlocked on power loss (typical of maglocks and some egress configurations); fail secure means locked on power loss (typical of most electric strikes and electrified locks).
