Access control applications
3.46 EST3 Installation and Service Manual
The command list operates the Signature relays on the Signature
data circuit supported by the Signature controller module. These
relays activate the gate opener, a spotlight, and a VCR image
recording system.
An inside card reader and could be used to control exits from the
area, but it would be more appropriate to use a motion detector,
since egress from the area is not controlled.
Power supply
A CRCXF—CRC Transformer power supply is shown,
assuming that the CRC is be located at some distance from the
electrical room and control panel.
If you use an additional power supply other than the CRCXF,
that power supply must be listed for fire alarm applications, must
have ground fault detection disabled, and must have a circuit
ground (circuit common) that is isolated from earth ground.
SDU programming
The SDU programmer must create a command list that specifies
activation of the correct relays and devices, the delays required,
and the deactivation of the devices.
Since there is no restoration phase of access events, the
command list should include commands that turn off the devices.
