- Chamber monitoring and Drift Compensation, Dual LED with 360° viewable design
- 5 Modes in 1 detector
- Self check facility
- 360° viewable design
- Common mounting base
This new conventional detector can be configured to operate as either an optical detector, opto/heat multi-sensor or 1 of 3 heat detector modes (A1R, BS, CS) using the four position switch located at the back of the detector.
The detector, having self check facilities, has a dual LED indicator.
The red LED is continuous to indicate alarm condition, the yellow LED is lit continuously to indicate a smoke sensing chamber fault or that the detector has reached the limit of its contamination compensating ability.
This LED can also be pulsed from the panel to locate wiring faults thereby saving time and cost by facilitating the fault finding process.
Can be used instead of CHT390 which is now obsolete
