Office Alarm Wiring
Access to Alarms Office alarms may be accessed on J6, located on the left side of the shelf
adjacent to the control unit. These alarms are provided on Form-C, or
transfer type contacts, allowing the alarms to be provided as normally
open or normally closed sets of isolated contacts, rated at 60 volts dc and
0.5 amperes maximum. The three connections associated with each
alarm are labeled NC, NO, and C. When an alarm occurs or power is
removed from the control unit, a closure exists between the NC and C
contacts and an open exists between the NO and C contacts.
Interconnections for remote Rectifier On/Standby and Plant Battery
Test of the power modules are also provided on J6. For proper operation
of the rectifier remote On/Standby function, a battery must be provided
with the -48V CPS system.
Hardware Kit A kit is available providing the connector and associated hardware to
fabricate an office alarm cable. (See Section 3, Engineering and
Ordering.)
Wire to the office alarms provided on J6 as required.
Caution
Alarm contacts are not fused within the unit; current limiting
protection for these contacts must be provided by external circuits.
Exceeding these maximum ratings could result in fire or damage to
the unit.
