Question: Electromagnetic locks on exit doors released by the fire alarm system must release:

Answer options:

  • Within 60 seconds of signal detection
  • Exclusively during the second stage of a two-stage system
  • Only after a manual bypass is reset ✅ Immediately upon an alarm signal being initiated

Correct answer: Immediately upon an alarm signal being initiated

Explanation: Usually 90-120 seconds. NBCC 3.2.4.15(1) specifies that electromagnetic locks must release immediately when fire alarm goes off or if power fails. Time delays are strictly regulated (max 15s in most 'delayed egress' cases, but for standard fire alarm, it is immediate). 15 seconds is the common 'delay' permitted ONLY in specific settings. S524 for door release states the release must occur within 10s of the alarm. 3.2.4.15(1)(e) says 15s max. Wait, the question asks for the standard ancillary release time. S524 13.3 states they shall release 'upon an alarm'. Generally accepted limit is <10s. Distractor 15s is for delayed egress hardware. Correct is 'Immediately'. Meaning within system processing time.
