The ACC-EN(SCI) is a multi-sensor detector featuring an integrated short-circuit isolator (SCI). It is fully compatible with Hochiki’s ESP Analogue Addressable Protocol and combines a thermal sensing element with a high-performance photoelectric smoke chamber for reliable fire detection.
The ACC-EN(SCI) offers three selectable operating modes, configured via the control panel¹, enabling detection using the optical element, the thermal element, or a combination of both to determine a fire condition.
Sensor polling LEDs may be configured from the control panel to operate in either pulsing or non-pulsing mode¹.
For ease of maintenance, the ACC-EN(SCI) smoke chamber is fully removable and replaceable.
To ensure full SCI functionality, the detector must be installed with the YBV-R/4 mounting base.
¹ Control panel compatibility should be verified.
