Programmable input
Programmable input
A programmable input is provided, the programmable input operates by means of an external
VOLT FREE SIGNAL. On no account should any voltage be applied to these terminals.
Whenever these terminals are shorted together, the panel will instruct all luminaires to enter
emergency mode. When the terminals are open circuit the panel will instruct all luminaires to
return to normal mode.
This facility is useful to provide a simple interface between the emergency lighting and systems
such as fire alarms.
Volt Free Contacts
24V Auxiliary output
A single set of volt free changeover contacts is provided, these enable a simple means of basic
interfacing with external equipment by providing a volt free signal in the event of a particular
event .
A 24V output is provided to drive suitable external equipment such as network booster devices,
this output is rated at a maximum of 300mA.
The output is not monitored and is not battery backed so will cease to operate if the mains
supply to the Easicheck panel is removed.
External Connections
Mains Supply
The mains supply should be installed in accordance with the current edition of the IEE wiring
regulations. Connection to the mains supply must be via an isolating device (e.g. an isolating
fuse) reserved solely for the Easicheck system.
Network Data Loop
Networking
Up to Sixty three Panels can be networked together to operate as a single networked system.
To achieve this each panel must be fitted with a network card (Optional Extra).
When operating as a networked system all status and fault event information is displayed at
every panel, resetting of panels can also be carried out from any panel on a networked system
if panels are suitably configured.
Networked panels are connected using a loop topology as illustrated.
The recommended network cable for the network connection is detailed in the current
installation planning guide along with recommendations for maximum cable lengths etc.
