This is the simplest form of an IR read/write head with the write line green and the read line brown. Brown is put to ground when TR1 (the photodiode) is lit. So you could hook up this part "(+) brown - black (-)" to a pulse port. BUT normally this kind of head is used for communication with a device, not pulse detection. Also you cannot guarantee the full switching of TR1 what the FLM would "need"; normally there is a Schmitt-trigger behind...
