on the next, and J1:2 on the first to J1:3 on the next. The last unit in the series has to be
strapped. Strap J1:1–2 on the 9dLD.

3 Reed relay, SW1, is connected in series with the monitor output. The relay closes when a
magnet is placed near to and parallel to it. The magnet in the 9dLD lid is placed so that the
relay will open in case of any physical damage or tampering.
NOTE: When the case of the 9dLD is put together, make sure that the reed relay
and the tamper protection magnet are placed opposite each other.
