The base is a completely new design with a large open working area and single quadrant terminals.
Other features include two fixing centres, a guide on the base interior to indicate the length
of cable to be stripped and E-Z Fit to make fitting to a BESA box easier.
There is also a continuity link that enables voltage testing of zone wiring prior to commissioning.
The link is automatically broken when the detector is first inserted.
The base also has a locking mechanism so that if detectors need to be locked in,
a marked part of the base is simply cut out to make it a locking base.
