standard double surface box supplied with the
program panel or recessed using a suitable flush
mounted double conduit box. see “Figure 5.2
Surface mounting back box dimensions” on page

Figure 18 Program panel
The program panel can be connected up to a
maximum of 16 air curtains in one network.
For mains wiring refer to the wiring diagram relating
to the model being used see “Wiring diagrams.” on
pages 19 to 21
The program panel is connected to the base unit in
the air curtain via pre-wired RJ45 cable/plugs. These
cables are available in 2, 10, 20, 30, 50 and 100m
lengths. It is recommended that this control cable
is run separately within its own trunking to avoid
external interference.
Maximum cable run in any network
must not exceed 100m in total
including program panel cable.
Note
: All air curtains connected within the
network system will operate under the settings
of the single program panel.
Any air curtain within the network can be
connected with and respond to the following
optional circuits:
• External switch (ie BMS enable) where required,
to be volt free and wired in PARALLEL via
normally open contacts to each terminal pair
‘TIMER’. (Contacts closed to enable). Only air
curtain(s) wired this way will respond to the
enable signal.
• Door switches where required, to be volt free
and wired to INDIVIDUAL base units via normally
closed contacts to each terminal pair ‘DOOR’.
(Contacts open to enable door mode). Only air
curtain(s) wired this way will respond to the door
mode.
• An external sensor, where required, can be wired
to INDIVIDUAL base units to each terminal pair
‘EXT’. Only air curtain(s) wired this way will
respond to the sensor setting.
