The BRK 700 series smoke and heat alarms are identical to the BRK 600 series alarms with the exception of the base. BRK 600 series alarms are supplied with a standard twist on base whereas the BRK 700 series are supplied with a DS700 push/click style base.

Both the 600 and 700 series alarms are compatible with the DS700RF radio-interlink base and both ranges will fit on either the twist or the push/click bases.

Safelincs stock the 600 series in the MBX variant (replaceable 9V back-up battery) with standard twist base and the 700 series in the MRL variant (sealed rechargeable lithium back-up battery) with the DS700 push/click base. Please note BRK also offer the 600 series MRL and 700 series MBX, however, these versions are not currently available at Safelincs.
