Answer:
The MI-WSS-PR-N communicates via the Morley-IAS protocol and installs directly onto the standard Honeywell Morley-IAS B501AP mounting base. It connects using terminal wire gauges from 1.5 mm² to 2.5 mm² and utilizes two rotary decimal switches for loop addressing.
The Honeywell Morley MI-WSS-PR-N is built for seamless field integration across addressable Morley-IAS fire detection infrastructures:
- Mounting Base Compatibility: Mounts onto the universal B501AP base, sharing a common footprint and mounting method with Morley-IAS addressable detectors.
- Pre-Commissioning Testing: The B501AP base integrates a shorting spring that permits circuit continuity testing across loop wiring before the active MI-WSS-PR-N head is locked into place.
- Cable Terminations: Features large cable entry access accommodating both surface and rear cable feeds, with terminal blocks supporting 1.5 mm² to 2.5 mm² solid or stranded conductors.
- Addressing: Loop address selection is set directly on the device using rotary decimal switches.
- Loop Synchronisation: Automatically synchronises sounder tone cadence and visual strobe flash rates across loop circuits when managed by Morley-IAS control panels.
