The Simplex 252-019 is a replacement B-key (CAT 30) used with Simplex fire alarm control panels and pull stations that require key-operated reset, test, or access functions. Maintaining a supply of replacement keys is essential for facilities management teams responsible for Simplex fire alarm systems, as these keys are required for routine testing, alarm reset, and access to key-locked components including pull stations, annunciators, and FACP doors.
The 252-019 key is the standard B-key used across a wide range of Simplex equipment. Keeping spare keys on-site prevents service delays when a key is lost or damaged. Life Safety Consultants supplies these keys individually and in multi-packs to meet the needs of facilities with large Simplex installations.
