Queensland Fire and Emergency Services’ Recommendation
• All residential accommodation be fitted with photoelectric type smoke alarms.
• Smoke alarms either hard-wired or powered by a 10-year lithium battery.
• Smoke alarms located – ; on each level of living space; outside each bedroom; and ; in every bedroom
• All smoke alarms should be interconnected.
• Every home should have a practised escape plan.
Interconnected smoke alarms is when one smoke alarm is activated, all interconnected smoke alarms are activated. The connecting of smoke alarms can be done wirelessly (via RF module) or hard-wired. The time occupants have to escape is increased.
Power supply options for smoke alarms
You can buy smoke alarms from hardware stores, electrical retailers, or through your electrician. There are two power supply options for smoke alarms – battery or hard-wired.
Hard-wired Smoke Alarms
A hard-wired smoke alarm is connected to a home’s electrical system and has battery back-up power supply.
• Considered more reliable in the longer term.
• Uses a battery to provide back-up power if the AC power fails. Back up batteries can be either 9-volt or built-in and tamper proof rechargeable lithium.
• Power-on indicator.
10-year Lithium Cell Battery
A 10-year lithium cell battery can be used in smoke alarms that are stand-alone or connected to a home’s electrical system.
• Easy to install.
• Has long term reliability.
• Battery cannot be removed.
• Less expensive than hard-wired.
9-Volt Smoke Alarms
A 9 volt smoke alarm, also called battery operated smoke alarms, are stand alone and operated only by a battery. These are the minimal legal requirement and do not provide the best safety for occupants.
Inside each bedroom, in the hallway and living areas, and connected together.
