Optional Dry Contacts
This option must be specified at time of ordering, along with the pre-programmed messages required.
The purchaser should also order the dry contact interface box (Part Code: DC) for ease of connection
to the contact terminals (see Diagram 2).
Warning!
Voltages applied to any of these contacts will cause irreparable damage!
This unit can support up to 10 dry (volt-free) contacts on PL1, which, when shorted out, will send a
pre-programmed message to a particular pager address (which could be to an individual, a group or
all pager operatives at the same time). These messages are pre-programmed and can only be
changed by qualified service personnel.
The trigger time required to send a message must be greater than
1 second.
Individual messages can be sent upon both changes of state with a maximum alphanumeric length of
80 characters or 20 numeric digits.
As a default, contacts are programmed as Normally Open (N/O), with a repeat transmission every two
minutes if still active.
Note: repeats are not available where contacts are programmed as Normally Closed (N/C).
