Relay Terminals & Power Supply
Relay Terminals
These terminals are for signalling the access control device. For loads over 2A we do not
recommend connecting directly, and use a secondary relay as a buffer instead.
NO Relay normally open contact
COM relay common terminal
NC relay normally closed contact
Exit buttons and Emergency Fire Exit delays are not provided by GymMaster however we have
included suggested wiring below.
As access control devices are often inductive, switching off the current can cause a voltage spike
on the wires to the access control, damaging the reader. A snubber should be fitted near any
switch or relay contacts, for DC circuits a silicon rectifier diode such as IN4001 is well suited.
12V Supply
Connect a 12V supply capable of at least 600mA, the socket suits a 2.1x5.5mm barrel connector
with the centre positive, or a screw terminal for hard wired power supplies.
