Any contact may be configured as:
• Latent route trigger
The contact triggers a latched or non-latched latent route, or a route where the associated DVAs are
played once only.
When configured to trigger a latched latent route, a separate contact must be specified as a reset
contact.
See Section “14.2 Configuring a Contact for Routing”.
• External fault input
The contact is configured as fault status inputs from external equipment.
See Section “14.3 Configuring a Contact as an External Alarm”.
• Remote fault accept
The contact acts as a local fault accept button of a remote fault panel.
See Section “14.4 Configuring a Contact as Remote Fault Accept”.
See Section “9.2 Contact Music Selector Configuration”.
• Music A/B selector
The contact is configured as a control to switch between Music A and Music B phono inputs.
L
Contacts 1 to 10 only use a non-isolated analogue interface with an internal pull-up to 5V and
may operate in two modes: ‘non-monitored’ to interface a simple contact closure to ground; or
‘monitored’ to interface resistively monitored contacts. Each contact is individually selectable
between these two modes, as described in the following sections.
