2. MULTI-SENSOR FIRE ALARM FEATURES
The state of the art EI2110 Multi-Sensor Fire Alarm, with its Heat enhanced Optical
Smoke Sensor, has a significantly improved performance as described below.
1. Faster Response to a wider range of fires.
The combination of the ultra fast temperature sensing thermistor and the high
performance optical sensor within the unit, enhances the fire sensing performance
such that the unit detects all the 7 different Test Fires (TF) specified in the standard
BS ISO 7240-15: 2004. These Test Fires are designed to produce different levels of
smoke/heat and as such are a good test of the units performance to the different fires
that could possibly occur in the home.
2. Reduced Nuisance Alarms.
The unit can tolerate up to 50% higher levels of cooking fumes and steam when
compared with normal optical sensor alarms.
3. Increased Longevity and Ruggedness.
The unit can tolerate up to 100% more dust and contamination build-up when
compared with normal optical sensor alarms. This is due to the unique automatic
DUST* compensation built into the unit which monitors the contamination in the smoke
sensing chamber and adjusts the alarm trigger point accordingly.

Additionally, the optical sensor chamber features a fine mesh insect screen that is
bonded to the plastic of the chamber. This significantly improves immunity to insect
contamination.
