Functional detector bases use a common moulding which incorporates a double sided circuit board which enables electrical connections to be made on the top
and bottom of the functional base. This allows the functional bases to be
retrofitted into new and existing universal bases or alternatively the depth and
cost of the installed detector can be reduced by using the functional base
instead of the universal base.

This feature enables additional sounders to be easily added during
commissioning. In addition, changes to the building during its life can be easily
adapted to, by retrofitting sounders and relay outputs to existing detection
points.

When functional bases are fitted to universal bases, they automatically lock into
position. Removal is then achieved using the detector removal tool. This feature
ensures that the detector and functional bases are removed separately.

• Dual pole 24Vdc relay contact (60VA).
• Status indicator LED.
• Low power consumption (<20μA except start up).
• Latching operation.
• Can be used instead of a standard base.
• Requires diode fitting if used in place of a diode base.
