Outputs
The IRC-2000 has eight outputs; four relay outputs and four solid-state outputs. Outputs
1, 2, 5, and 6 are dry contact relays (UL rated 2A @ 30v dc). Outputs 3, 4, 7, and 8 use
electronic drivers and can switch up to 100ma. The URC-2000 has four outputs, two
relay outputs and two solid-state outputs. Outputs 1 and 3 are dry contact relays (UL
rated 2A @ 30v dc). Outputs 2 and 4 use electronic drivers and can switch up to 100ma.
All outputs are programmable from the PC as „On State‟ energized or „On State‟ de-
energized. „On State‟ de-energized outputs are used for fail-safe operation where it is
essential that the output return to a safe state when the system fails due to power loss,
communications failure, or fire.
Electronic outputs are „switched negative‟ which means that they switch the power
negative to the terminal. When the output is off, the output terminal is electronically
disconnected. Outputs can be programmed for lock or handicap operation (as described
below), or they can be used as general-purpose outputs.
Lock Output
The lock output is used to activate or deactivate the locking device on the door. It can
apply power to door strikes or remove power from magnetic locks.
Handicap Output
This output is used to drive door operators. It turns on in less than one second after the
Lock Output is turned on, and stays on until the Lock Output is turned off. Only
designated cardholders will activate this output.
Alarm Shunt Output
This output is activated at the same time as the Lock Output and is used to bypass the
door contact of a burglar alarm panel. The Alarm Shunt Output will reset with the
closure of the access control panel‟s door contact (the Alarm Shunt Output will stay
activated past the Unlock Time as long as the door is open). A door with two contacts
(one for the burglar Alarm and one for the access control) will require an Alarm Shunt
Output to prevent the burglar alarm system for going into alarm during a valid entry.
Modem Power Output
The Modem Power Output is a normally activated output that is used to reset a modem
by momentarily removing the power from the modem.
General Purpose Output
General Purpose Outputs are outputs that are user controlled. They are activated and de-
activated by user defined links and schedules.
