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
How do I House Code RadioLINK+ / RadioLINK Products?
RadioLINK+ and RadioLINK use Radio Frequency signals for wireless interconnection making installation quicker and easier. Once you have installed all your RadioLINK products you will need to set them up in a system to recognise each other and then close this system off to avoid the alarms being triggered by neighbouring systems – we call this House Coding.
- Step 1 – Ensure all your alarms have been installed and tested and you have inserted your Ei100MRF modules into your 160e Series and Ei2110e alarms
- Step 2 – Push a screwdriver into the House Code slot on the side of the alarm or RadioLINK base
- Step 3 – Hold it in until the blue LED comes on solidly, then release
- Step 4 – Remove the screwdriver and the blue LED will flash once every 5 seconds (approx.) to indicate that it is in House Code mode and is looking for other alarms
- Step 5 – Repeat the House Code process in Steps 1-4 above with all the bases or alarms in your system
- Step 6 – All the bases in the system will start to flash blue. Check that the number of flashes is the same as the number of alarms in the system, e.g. if there are 3 alarms, the blue LED will flash 3 times every 5 seconds on every alarm
- Step 7 – Once the correct amount of flashes is present on every unit, insert a screwdriver into the House Code slot on the side of one of the alarms or bases until the blue LED comes on solidly, then release
- Step 8 – The blue LEDs on all units will now stop flashing and the entire system will automatically ‘seal’
- Step 9 – The alarm system has now been House Coded. Press and hold the test button on each alarm in turn and check that all alarms in the system sound
Although we recommend the above procedure for House Coding and sealing a RadioLINK system, it is worth noting that the system will manually seal itself after 30 minutes once put into House Code mode.
RadioLINK+ additional features
RadioLINK+ units have an additional ‘remote House Coding’ feature which makes it easier to add new units to an existing system that has already been House Coded
- Step 1 – push a screwdriver into the House Code slot on one of the existing House Coded units and hold until the House Code LED flashes a green, blue and red tri-colour. This will put all the existing RadioLINK+ alarms in the system into Remote House Code mode
- Step 2 – A new alarm can then be added into the system. Put the new unit into House Code mode as described above and again check the number of flashes matches the number of units in the system. Once the number of flashes on all units is correct, seal the system and test as described above
