Description

The Honeywell Morley HM-HTSE-S2I-IV is a low-profile, addressable thermal sensor engineered specifically for areas where high ambient temperatures are common or rapid temperature fluctuations occur, such as boiler rooms or commercial kitchens. Utilizing advanced thermistor tech and a localized microprocessor, the device accurately monitors environmental conditions and triggers a definitive alarm condition when temperatures reach a fixed threshold of 78°C (Class BS). Equipped with an internal short-circuit isolator, this unit safely maintains data loop continuity across the broader fire alarm network during an electrical fault, supports both Advanced and CLIP communications, and allows simple manual addressing via mechanical rotary switches.

Features

  • Circuit Protection: Integrated short-circuit loop isolator ensures a single wiring fault won’t drop the entire communication loop.
  • High-Temperature Targeting: Optimized at a fixed 78°C threshold to provide reliable fire detection in environments prone to high ambient heat without causing nuisance alarms.
  • Protocol Tuning: Fully compatible with Honeywell’s Advanced Protocol for rapid communication, digital noise filtering, and high data loop integrity.
  • Manual Addressing: Uses mechanical decadic rotary decade switches, eliminating the need for specialized electronic tools during installation.
  • Status Diagnostics: Tri-color LED indicators blink green during polling, show amber for faults, and hold red for active alarms.
  • Backward Compatibility: Offers 100% electrical and mechanical compatibility with legacy platforms and standard B500 series bases.
