Office Alarm Cable Installation
Description
Office alarms are the common method used in a central office for
maintenance personnel to quickly isolate a failure. Perform this
procedure if connection to the office alarm system is required.
Important!
The office alarm relay contacts are rated at 50 VA
which means that they are capable of switching 1 amp at 50 volts,
or 2 amps at 25 volts. Their ability to switch large transient currents
means that they can, if necessary, switch up to ten 5-watt aisle pilot
lamps.
If transient voltages or currents are above these limits, transient
noise-suppressing devices such as diodes or contact protection
networks must be used to keep within the voltage and current limits. If
these protection devices are not sufficient, an external buffer relay
MUST be provided.
In all cases, and as a matter of good practice, suppression devices such
as diodes or contact protection networks must be provided across any
external relay coil being driven by the Metropolis

DMXplore to limit
transient voltages and currents.
Office alarm cable assemblies are listed in Table 1-9, Office Alarm
Cable Assemblies (page 1-33) and Office alarm connection are listed in
Table 1-10, Office Alarm Connections (page 1-34).
