Product Overview

The Ei603RF heat alarm has a sealed 10 year lithium battery designed to last the full lifetime of the alarm with a built-in RadioLINK+ module allowing it to wirelessly interlink with other RadioLINK and RadioLINK+ devices, ensuring occupants have the earliest possible warning of a fire in the property. Heat alarms detect fire by sensing the rise in temperature in their surroundings rather than sampling the air, meaning the Ei603RF is suitable for the loft, kitchen, or garage where dust and fumes may cause nuisance alarms with other types of detector.

  • Battery: Built-in, lasts the lifetime of your alarm
  • Warranty: 5 year warranty
  • Easy to install with a twist-on base design
  • Alarm performs a self-test every 16 seconds
  • RadioLINK+ wireless technology built in

  • Optional adhesive pad can be added before checkout
  • Suitable for installations complying to BS 5839-6: 2019 Grade F1
  • Screws and fixings supplied with the alarm

Wiring Explained

Mains powered Ei Electronics smoke and heat alarms require a 230V AC power supply and up to 12 alarms can be hardwire interlinked in one system.

To obtain a mains power supply, each alarm can be connected to the nearest lighting circuit using 2 core and earth cable with a separate, dedicated interlink cable connecting alarms where applicable. However, if possible it is recommended that any alarms connected via interlink cable are all powered from a dedicated circuit from the distribution board using 3 core and earth cable for safety during maintenance, as the interlink cable will carry power from live alarms on other power circuits. Please see the diagram below:-

FAQs (8)
Q. How can we test the alarm to make sure it is working?
A.

The manufacturer's recommendation is to test the alarm by pressing the test button. This will simulate a heat input at the heat sensor. You can also test it with a hair dryer but make sure that the hairdryer is kept away at a suitable distance from the alarm. Do not attempt to test the alarm by using open fire or excessive heat as this may damage the unit.

Q. Is it possible to have a heat alarm mains powered radio interlinking alarm interconnect with battery powered radio-interlinked alarms?
A.

Yes this entirely possible. The Ei140 series with RF base is mains powered and these are compatible to interlink with the battery operated Ei3100 series. Please view the interconnection overview on either of these alarms for further details.

Q. Do the Ei600 series alarms need 230v or do they just use battery?
A.

The Ei600 series of radio-interlinked alarms are completely battery operated. This means that they do not need to be wired up to the mains circuit. On the website, we offer the Ei600 series with a standard 9v battery or with a 10 year lithium longlife battery. The standard 9V batteries last approximately 12-18 months depending on how often the detectors are tested. The lithium battery units are sealed and last 10 years i.e. the full lifespan of the detector.

Q. Where more than one radio-interlinked battery operated smoke alarm is installed, if the battery in one alarm failed would the other alarms be affected?
A.

If one alarm was to malfunction the other units would not be affected, if it was due to alarm failure. If the fault was with the radio-interlinking signal, then all alarms that are in the chain after the faulty alarm would be affected and they would not go off.

Q. Do the radio interlinked units give out a constant signal all the time and does this decrease the battery life more than a non-interlinked alarm?
A.

Yes, radio interlinked alarms are periodically sending and receiving signals from other units in the network and therefore the life of the battery is reduced. Units with alkaline batteries should have the batteries are changed annually [unless they are fitted with a sealed 10 year battery as eg in the Ei600RF series].
