10.2.3 TB-10 - Door Held Open Alarm Relay Connection
These instructions apply if the enhanced alarm out annunciation feature (in the Doors
software) has configured these outputs to door held open annunciation. Otherwise skip
to the TB10 - General Purpose Output Relay Connections section starting on page 87.
The Door Held Open Alarm Relay is a Form C relay that provides an output to trigger
an audible signal (or a silent alarm) whenever the door is put into an alarm state;
whenever the door is held open too long (exceeding the Open Time set within the
Doors access control program). General-purpose output four can be configured to be
the door held open alarm for the A-door on the PXL-250 controller. General-purpose
output 3 can be configured to be the door held open alarm for the B-door on the SB-
293 satellite board. Refer to the Door Held Open Alarm Relay output section on
page 36 for more information on alarm relay outputs and output devices.
For a typical door held open alarm relay installation for the A-door, refer to Table 25
and Figure 10-6, both on page 78, and make the following wiring and transorb
connections to attach the door held open alarm relay.
For a typical door held open alarm relay installation for the B-door, refer to Table 26
and Figure 10-7, both on page 79, and make the following wiring and transorb
connections to attach the door held open alarm relay.
