Apollo Series 65 Diode Base 45681-201 The Series 65 Diode Base is designed for use with conventional systems that have manual call points and detector bases on the same circuit. The base is fitted with a schottky diode on the L1 IN" and "L1 OUT" wiring terminals. This base can only be used with compatible control equipment. Operation All detectors in the Series 65 range fit into Series 60 standard mounting bases. The bases are of 100mm diameter and have five terminals marked according to their function Line 1 in, line 1 out, line 2 in and out, remote indicator negative, earth. Detectors are polarity insensitive, so that identification of positive and negative lines is only required if a remote LED is fitted. An earth connection is not required for either safety or correct operation of detectors. The earth terminal is provided for tidy termination of earthed conductors or cable screens and to maintain earth continuity where necessary. Bases have a wide interior diameter for ease of access to cables and terminals and there are two slots for fixing screws at a spacing of 51 to 69mm. Detectors fit into bases one way only and require clockwise rotation without push force to be plugged in. Key Features Detector locking mechanism One way fit Easy to wire Contains an earth connector Continues to work during unauthorised removal of detectors Brand Features Wide-operating voltage of 9�33 V DC Wide-operating and storage temperature of -20C to 60C Can be used on security systems Electrically and mechanically compatible with Series 60 Proven detection performance"
