In applications where immediate egress during a power failure is a safety requirement, mechanical-lock models are highly preferred because they stay physically locked unless overridden by the mechanical override key. This contrasts with solenoid-lock models (such as the D4BL-2GRA) which unlock immediately upon power loss, a behavior that may be dangerous in processes with long run-down times.\u003c\/p\u003e\n\n\u003ch4\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eDuring system integration, ensure that the solenoid coil is not continuously energized for prolonged periods exceeding the design parameters, as continuous excitation will cause thermal stress.
