The ASE or AIU/PPU should be powered from the fused DC distribution board on the
power supply. It is recommended that the brigade device does not share its fuse
protection with any other equipment, for reliability.
The wiring between the brigade device and the 4100U-S1 should be routed neatly as
shown in the following drawings, and secured in place with the cable ties and adhesive tie
holders supplied with the kits.
Fit the protective earth lead between the quick-connect tap on the brigade interface door
and an unused stud in the lower right end of the expansion bay, using the nut and washers
supplied with this kit.
The AIU or PPU must be obtained separately. The AIU is fastened directly to the spacer
bracket on the brigade interface door by four screws supplied with the AIU. The PPU
mounts on the spacer bracket using four screws and plastic standoffs supplied with this
kit. See drawing 1901-267 sheet 2 for details.
The pre-fitted wiring must be connected to the 4100U-S1’s Alarm Relay Card terminals
as shown in 1901-267 sheet 2. Set the three links on the Alarm Relay card to the NO
positions for an AIU and the NC positions for a PPU. Note: the red wire has some extra
length, for use in linking the terminals together as shown. Both AIU and PPU require
extra wire links on the Alarm Relay terminals, and the PPU requires extra wire links on
the connector strip on the door.
The ASE must be obtained separately. If it is supplied complete with a body, this must be
removed before fitting the ASE to the door. The ASE is fastened to the brigade interface
door with the two M4 screws and crinkle washers in the kit. The antenna socket should
be fitted to the tab on the door below the ASE position. See drawing 1976-174 sheet 1 on
page 4 and the ASE installation instructions for details.
The FP0740 ASE FAS module must be connected to the 4100U-S1’s Alarm Relay Card
terminals and the 2 way ASE connector as shown in 1976-174 sheet 1. Set the three links
on the Alarm Relay card to the NC positions.
