Answer:
The Honeywell Morley MI-WSS-PR-N operates across a 15 to 29 VDC supply voltage with a standby current of 120 µA (non-isolation) or 225 µA (isolation). It generates an acoustic output up to 97 dB(A) ±3 dB at 1 metre across 32 selectable tones, with a maximum combined sounder and strobe current draw of 14.5 mA at 15V.
The Honeywell Morley-IAS MI-WSS-PR-N is an addressable wall-mounted audio-visual notification appliance engineered for loop-powered operation on compatible fire alarm systems. Key performance ratings and operational parameters include:
- Operating Voltage: 15 to 29 VDC (supported in both isolation and non-isolation configurations).
- Standby Current: 120 µA in non-isolation mode; 225 µA in isolation mode.
- Maximum Operating Current: 14.5 mA maximum for combined sounder and strobe operation (rated at High Volume, Tone 11 at 15 VDC).
- Acoustic Output: Up to 97 dB(A) ±3 dB at 1 metre (measured at High Volume, Tone 8 at 24 VDC; based on high-volume 970 Hz continuous operation).
- Tone & Volume Options: 32 selectable tone patterns with 3 volume settings (High, Medium, Low).
- Visual Indicator Flash Rate: 1 Hz beacon strobe flash rate.
- Unit Weight: 0.238 kg.
