Description
ISO 7240 is a family of international standards for fire detection and alarm systems. It specifies general requirements for the design, installation, commissioning, operation and maintenance of life-safety fire alarms, aiming for reliability and interoperability across manufacturers and countries. The series covers system architecture, detectors and sensors, manual initiating devices, control/indicating equipment, notification devices, power supplies, wiring, interfaces with other systems, and performance/testing criteria.
In practice, ISO 7240 guides how to select, design, and verify fire-alarm solutions, often harmonizing with regional standards (e.g., EN 54). It supports consistent safety, performance, and maintenance across products and installers.
ISO7240CFQDWRQ1 looks like a vendor-specific part number rather than a published ISO standard. If you’re dealing with a device labeled that way, consult the supplier’s datasheet and map the product to the relevant ISO 7240 parts to confirm compliance and interoperability.

Equivalent
Equivalent parts (1-channel digital isolators with similar 3.3/5 V operation and ~5 kV isolation) include:
- Analog Devices ADuM1250 / ADuM1251
- Silicon Labs Si86xx family (single-channel digital isolators)
Note: exact cross-reference depends on voltage, isolation, and package; check TI’s cross-ref for ISO7240C (FQDWRQ1) and match specs (channel count, voltage, isolation).
