Addressable multi-criteria smoke and heat detector is a loop-connected fire detection device. Integrating both an infrared photoelectric chamber and a thermistor sensor, it monitors both smoke and heat for fire warning.
Available size
| Operating voltage | Standby current | Smoke sensitivity level | Heat detection type | Ref. No. |
|---|---|---|---|---|
| 24 VDC | ≤ 0.4 mA | 3 | FT 135°F | A1301 (UL) |
| 24 VDC | ≤ 0.16 mA | 4 | FT 135°F / ROR | A1311 (UL/FM) |
Note: For heat detection type, it is fixed temperature (FT), or combination fixed temperature and rate-of-rise (FT/ROR).
