secure electrical connection through the clamped contacts when mounting the detector. The
bases are provided with three mounts for cable ties. These can be used for fastening the base
during the wiring‑up.

panel series 1200 and 5000.
In cases where relay bases are used, no external detector alarm display can be connected.
