As part of the improvements to the System Sensor range of detectors the System Sensor 1151EIS Intrinsically Safe Ionisation Smoke Detector has been superseded by the System Sensor 1151EISE Intrinsically Safe Ionisation Smoke Detector.
The System Sensor 1151EISE features enhanced aesthetics and is compatible with the same bases utilised with the System Sensor 1151EIS detectors.
