5.2.4 Emergency Override/Free Exit
There is a special case where both the RTE and DC signals are interpreted differently to the way
described for door monitoring in Section 5.2.2.2. The RTE signal is used to monitor an emergency switch,
such as a break glass, and DC provides a Free Exit report.
Note
When this feature is used there is no door monitoring. For details on how to enable this feature,
see the D command in 15267 PAC Portico 2200/1200 Series Door Controllers User Guide or refer
to the documentation supplied with the administration software.
Figure 23 Emergency Override / Free Exit Wiring
Emergency Override
When connected as shown in Figure 23, operating the break glass will open the door and generate an
Emergency Override On report. When the switch is restored, the controller will re-lock the door and
generate an Emergency Override Off report.
WARNING
THIS FEATURE SHOULD NOT BE FITTED AS THE SOLE MEANS OF ESCAPE.
Free Exit
When this option is set, pressing the Request to Exit switch will produce a Free Exit report. The door
contact will allow door left open warnings to be produced.
A normally closed switch may be used to operate as a request to exit switch, in addition to having a door
contact switch in series (see Figure 23).
Notes
1. Using this arrangement, the lock will operate whenever DC is opened - this means that care
should be taken that the door contact cannot be broken from the secure side of the door.
2. As free exit was designed to work with a door contact or pushbar the door contact “bounce time”
is applied and the response will be slow if used like an Request to Exit switch (1.25 seconds).
3. For details on how to enable this feature, refer to the documentation supplied with the
administration software.
