Ei146RC Optical Smoke Alarm
The Ei146RC Optical Smoke Alarm is a mains powered alarm with a 9V Alkaline battery back-up and contains a large, proven optical smoke chamber.
Different alarms sensors work best at detecting different types of fire and so should be sited in appropriate rooms throughout a property. Optical alarms are best at detecting slow, smouldering fire which are commonly caused by sofas or electrical fires.
Fit in: Hallways, Landing, Livings Room, Dining Room
By fitting an Optical alarm in these areas you are less likely to get nuisance alarms, especially if the alarm is located close to the Kitchen.
The alarm is supplied with an easi-fit base to make it as quick and simple to install. As with the rest of the 140RC Series alarm the Ei146RC Optical alarm can be interconnected with other alarms and accessories through hard wire connection or, for less mess and disruption, by RadioLINK wireless interconnection.
As this alarm contains a 9V Alkaline battery back up, this battery will need changing over the course of it’s ten year life.

How do I change the battery?
There are two different types of batteries used as battery back ups in our mains powered smoke and heat alarms. Many of these are sealed in Lithium cells, that last the 10 year life of the alarms. Our 140RC range contains a 9V Alkaline battery as it’s back up power supply and this will need changing across the life span of the alarm.
You will know when you need to change the battery, as you will hear a single regular beep (low battery warning) coming from the alarm, however it is recommended that you change the battery every year.
How to change the battery in 140RC Series Alarms
Turn off the mains power to the alarm. The green light on the alarm should go out
Insert a flat headed screwdriver into the removal slot of the alarm. This is marked with an arrow. Make sure you keep the screwdriver horizontal (i.e. parallel to the ceiling)
Slide the alarm off its base and you should be able to see the 9V battery in the back
Replace the battery in the back of the alarm with a 9V Alkaline battery – we recommend Duracell MN 1604 or Energizer 522 batteries. Take care with the battery clip and wires as damage to these will result in constant beeps, meaning that the unit will need to be replaced
Slide the alarm back on its base
Turn the power back on. The green light on the alarm should come back on
Finally test the alarm to ensure the unit is working correctly
