4. MULTI-SENSOR FIRE ALARM FEATURES
The state of the art Ei2110e 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 Alarm,
enhances the fire sensing performance such that the Alarm detects all the 7 different Test
Fires (TF) specified in the standard BS ISO 7240-15: 2014. These Test Fires are designed
to produce different levels of smoke/heat and as such are a good test of the Alarm's
performance to the different fires that could possibly occur in the home.
2. Reduced Nuisance Alarms -
The Ei2110e 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 Ei2110e 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 Alarms
which monitors the contamination in the smoke sensing chamber and adjusts the
alarm trigger point accordingly. *DUST –

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.
4. Alarm Memory -
After an alarm activation, the red alarm light will flash twice (1
second apart) every 48 seconds to indicate that the Alarm has sounded in the previous
24 hours. Additionally, pressing the test button on this Alarm will cause it to emit short,
rapid beeps instead of the normal alarm sound. Both these features allow easy
identification, for example, of the source of nuisance alarms during the night.
