Frequently Asked Questions

Genral Wireless Alarm Queries

Q. Are there any restrictions to the distance a wireless smoke alarm will work?

A. Most wireless alarms have a range of 150 meters in an open space and up to 30 meters in buildings. The thickness of the walls and partitions will affect the travel distance of the signal. Most units can be set up as a 'repeater' which will increase the distance by a further 30 meters.

Q. If the wirless signal on one unit fails will the units still work as stand alone units.

A. Yes, should the wireless signal fail the units will continue to sound independently should they detect a fire.

Battery Powered Alarm Queries

Q. Do batteries in wireless alarms expire quicker than those in normal alarms?

A. Batteries in wireless alarms do expire quicker than in other smoke alarms. Smoke alrms are also available with a 10 year sealed long life lithium battery. This battery will last for the 10 year life of the smoke alarm.

Q. Where more than one wireless 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 wireless signal, then all alarms that are in the chain after the faulty alarm would be affected and they would not go off.

Mains Powered Alarm Queries

Q. Why do your mains powered alarms have batteries?

A. All our mains powered alarms have a battery backup. Although mains powered alarms without this option do exist (BS5839 part 6 grade E), we regard them as far too dangerous, as a lot of fires are caused by electrical faults leaving the building unprotected against fire if the smoke alarms have no backup battery. With our mains powered alarms you will always be protected.
