The ACC-EN(BLK) is a multi-sensor device fully compatible with Hochiki’s ESP Analogue Addressable protocol, combining a thermal detection element with a high-performance photoelectric smoke chamber.
The detector offers three operating modes, controlled from the control panel, allowing the optical element, the thermal element, or both simultaneously to contribute to the fire detection decision. The sensor polling LEDs are also panel-controlled, with selectable pulsing or non-pulsing operation. For ease of maintenance, the smoke chamber can be easily removed or replaced.
