Test Keyswitch
A test keyswitch unit can be connected to the 'beam transmitter' to facilitate simulation of a test fire condition.
The test keyswitch function is supported on Vigilon system only. The keyswitch unit is required to have a
series resistor of value 470W coupled with an end-of-line 10KW resistor wired as illustrated below.
