Office Alarm Contacts
Introduction These are 60-volt, 0.5-ampere, Form-C or transfer type contacts that
allow an installer to connect the control unit to an office alarm system.
Each set of isolated contacts consists of a combination of normally open
(NO) and normally closed (NC) contacts with one side of each common
(C). When the control unit has power and no alarm condition exists, all
alarm relays are energized. When an alarm condition exists, the relay
de-energizes and a closure exists between the NC and C poles and an
open exists between the NO and C poles. If the control unit is powered
down, the alarm relays are de-energized and all NC and NO closures are
sent to the office alarm system.
