Addressable Detector Installation Manual - Polarity, Wiring, Address Setting

Sep 25, 2026

Installation instructions for an addressable detector, covering typical wiring, base installation, and detector head fitting. The guidance emphasizes observing detector polarity, maintaining earth screen continuity via an earth terminal, and ensuring clean, unobstructed base contacts. It specifies compatible MKII-A Series base models and provides step-by-step mounting and clockwise rotation to secure the detector. It also details electrical and environmental specifications, and explains dip-switch binary address setting with valid address constraints.

Typical Wiring Diagram Note: Polarity must be observed on detector as indicated on schematic wiring diagram. Earth terminal is provided to maintain earth screen continuity. It does not connect to this detector head. Base Installation Connect the zone wires to the appropriate terminal. Tighten with a correct sized screwdriver: a wrong screwdriver may damage the screw heads. Make sure that the base contacts are clean and unobstructed. Note, the base model No. for MKII-A Series is MKII-CB or MKII-CB/D. Detector Head Installation If there is still minor construction work in progress, the head may be fitted, provided that the dust cover is still in place. To fit the detector, mate the detector onto the base and rotate the detector in clockwise until the detector loads into the base. Continue to twist clockwise to secure it.

There can only be one device set to each address. The address is set with a dip switch located on the underside of the detector. There are 8 switches. Switches 1 to 8 are used to set a binary address, with the ON position being binary 0 (0 marked on the label), and the OFF position being binary 1. (1 marked on the label) Addresses 0 (all ON) and 255 (all OFF) are not used. The address can be set by following the table opposite, or by following equation Switch 1 OFF = add 1 to total Switch 2 OFF = add 2 to total Switch 3 OFF = add 4 to total Switch 4 OFF = add 8 to total Switch 5 OFF = add 16 to total Switch 6 OFF = add 32 to total Switch 7 OFF = add 64 to total Switch 8 OFF = add 128 to total | ADDR | 87654321 | ADDR | 87654321 | ADDR | 87654321 | ADDR | 87654321 | | --- | --- | --- | --- | --- | --- | --- | --- | | N/A | 00000000 | 32 | 00100000 | 64 | 01000000 | 96 | 01100000 | | 1 | 00000001 | 33 | 00100001 | 65 | 01000001 | 97 | 01100001 | | 2 | 00000010 | 34 | 00100010 | 66 | 01000010 | 98 | 01100010 | | 3 | 00000011 | 35 | 00100011 | 67 | 01000011 | 99 | 01100011 | | 4 | 00000100 | 36 | 00100100 | 68 | 01000100 | 100 | 01100100 | | 5 | 00000101 | 37 | 00100101 | 69 | 01000101 | 101 | 01100101 | | 6 | 00000110 | 38 | 00100110 | 70 | 01000110 | 102 | 01100110 | | 7 | 00000111 | 39 | 00100111 | 71 | 01000111 | 103 | 01100111 | | 8 | 00001000 | 40 | 00101000 | 72 | 01001000 | 104 | 01101000 | | 9 | 00001001 | 41 | 00101001 | 73 | 01001001 | 105 | 01101001 | | 10 | 00001010 | 42 | 00101010 | 74 | 01001010 | 106 | 01101010 | | 11 | 00001011 | 43 | 00101011 | 75 | 01001011 | 107 | 01101011 | | 12 | 00001100 | 44 | 00101100 | 76 | 01001100 | 108 | 01101100 | | 13 | 00001101 | 45 | 00101101 | 77 | 01001101 | 109 | 01101101 | | 14 | 00001110 | 46 | 00101110 | 78 | 01001110 | 110 | 01101110 | | 15 | 00001111 | 47 | 00101111 | 79 | 01001111 | 111 | 01101111 | | 16 | 00010000 | 48 | 00110000 | 80 | 01010000 | 112 | 01110000 | | 17 | 00010001 | 49 | 00110001 | 8

FAQs

What wiring rules must be followed when installing the detector?

Polarity must be observed on the detector as indicated on the schematic wiring diagram. An earth terminal is provided to maintain earth screen continuity, but it does not connect to the detector head.

How should the detector head be installed onto the base?

Mate the detector onto the base and rotate clockwise until the detector loads into the base, then continue twisting clockwise to secure it. If construction is still in progress, fitting is allowed only if the dust cover remains in place.

How is a unique detector address set using the dip switches?

Each detector on the loop requires a unique address. Use the underside dip switch with 8 switches set as binary: ON is binary 0 and OFF is binary 1. Switching OFF adds specific values (1, 2, 4, 8, 16, 32, 64, 128) to the total, and addresses 0 (all ON) and 255 (all OFF) are not used.
