This is the Apollo 45681-201 Series 65 Diode Base, designed for use with conventional systems that have manual call points and detector bases on the same circuit. This base is fitted with a schottky diode on the "L1 IN" and "L1 OUT" wiring terminals. 

  • It has a 100mm diameter and has five terminals marked according to their function: Line 1 in, line 1 out, line 2 in and out, remote indicator negative, earth. 
  • An earth connection is not required for either safety or correct operation of the detector; the earth terminal is provided for tidy termination of earthed conductors or cable screens and to maintain earth continuity where necessary. 
  • It has a wide interior diameter for ease of access to cables and terminals and there are two slots for fixing screws at spacing of 51 to 69mm. 
  • The detector fits into the base one way only, and it requires clockwise rotation without push force to be plugged in. The detector can be locked into the base by a grub screw using a 1.5mm hexagonal driver. 

Please note: This base can only be used with compatible control equipment, and for many of the conventional smoke / heat detectors this base is a require item.
