Answer:
The MI-WSO-PR-N features a red round ABS housing, mechanical rotary decade address switches, and a non-isolated circuit design designated by the '-N' suffix. It draws 120 µA in standby, offering an efficient notification solution on addressable loops.
The Honeywell Morley-IAS MI-WSO-PR-N carries specific design and configuration characteristics distinguishing it from isolated sibling models:
- Non-Isolated Configuration ('-N'): Designed without an integrated short-circuit isolator, drawing 120 µA in standby compared to the 225 µA standby consumption found on isolated variants.
- Addressing Mechanism: Uses traditional mechanical rotary decade switches on the rear plate, allowing direct decimal address setting without requiring external electronic programming tools.
- Enclosure & Build: Molded from flame-retardant red ABS plastic in a round form factor with an IP24 ingress rating when used with the standard B501AP base (up to IP44 or IP65 when used with dedicated deep backboxes).
