.
These instructions provide trained installation personnel with
details to install and commission 460 manual call points for
optimum performance.
Preparation
Before commencing installation, ensure all equipment and tools to
mount and connect the equipment are available, such as drills,
mounting screws, cables and ladders.
NOTE: The unit comes separated from the back-box, ready for installation.
However, if necessary, separate the front face from the body by inserting
the reset key and gently pulling the lower portion of the front face down and
away from the body. Removing the operating element will expose the
screws that hold the body to the back-box (see Figs. 3 ~ 5).
Installation
Back-box
1. Feed the conductors through the rear of the back-box.
2. Securely mount the back-box to the wall surface using fixing
screws and wall plugs. Fig. 1 shows the back-box mounting
hole dimensions.

NOTE: Where the 460-009 weather proof enclosure accessory is used, the
back-box is not used.
Wiring
The terminals accept (0.4 ~ 2.5) mm
2
conductors.
1. Strip the conductor insulation to expose 5 mm of the
conductor.
2. Connect the conductors to the terminals as shown in Fig. 2.
WARNING: Take care to ensure the insulation does not get
clamped by the terminal contact.
