Answer:
The HM-PTSE-AP integrates dual-criteria sensing—a photoelectric optical smoke chamber and a 58°C Class A1R fixed and rate-of-rise thermal thermistor—managed by embedded software algorithms. It supports programmable day/night modes to operate in heat-only mode during busy work hours, automatically reverting to combined photo-thermal protection when unoccupied.
The HM-PTSE-AP multi-criteria detector combines two distinct physical sensing elements within a single plug-in ceiling assembly:
- Optical Photoelectric Chamber: Employs an internal chamber with an optical smoothing algorithm and washable filter designed to screen out nuisance dust and particulate contamination.
- Class A1R Thermal Sensor: Provides thermal assistance including a 58°C fixed activation threshold and rate-of-rise thermal detection complying with EN 54-5.
- Multi-Criteria Processing: Embedded software continuously correlates optical smoke chamber inputs and thermal activity, delivering early warning to smoldering and flaming fires while rejecting false alarms.
- Day/Night Programmability: When configured through compatible control panels, the detector can be set to heat-only mode during operational hours where work activities generate airborne dust or steam, automatically reverting to complete multi-sensor photo-thermal surveillance during off-hours.
- Visual Status: Features dual integrated red LEDs providing 360-degree visibility for polling and alarm status.
