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: DC8) 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 8 dry (volt-free) contacts on PL1, which, when shorted to ground, 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
69 characters.
