INTRODUCTION
The
SIEMENS
Model CP-2ER Control Panel is a two-zone
local control unit which meets the requirements of NFPA
72 Local for a two-zone releasing device panel approved
in accordance with NFPA 12A, 13, and 2001 for cross zone
protection. The two initiating zones, Zone 1 and Zone 2,
may be connected for either Class A or Class B operation.
The two zones are arranged so that both must be acti-
vated in order to discharge the agent automatically into the
protected area.
As shipped from the factory, the CP-2ER is set to meet the
NFPA 72 requirements; that is, an alarm in either of the two
initiating zones causes the general alarm to sound. Once
the general alarm is silenced, an alarm in the other initiat-
ing zone causes the general alarm to sound again.
To set the CP-2ER to meet NFPA 12A, 13, or 2001 require-
ments for a releasing panel, place the
SERVICE SELEC-
TION
plug in position P12 (Release). With the plug in this
position
,
both a general alarm associated with the first ini-
tiating zone actuation and a predischarge/discharge alarm
with actuation of the second initiating zone will sound. The
position of the plug in P12 voids the NFPA 72 Local listing
since the general alarm circuit silences upon actuation of
the second initiating zone.
The Control Panel provides for the external connection of a
supervised manual discharge station for agent release, as
well as for several other supervised input and output func-
tions. Essentially, every supervised feature has its own sepa-
rate fault indicator for ease of troubleshooting the system,
should a fault occur.
Displayed through the front cover are the usual visual indi-
cators for power, system alarm, and system trouble, as well
as several additional specific function indicators. Within the
Control Panel are a fire alarm
RESET/LAMP TEST
switch,
an
ALARM SILENCE
switch, a
SUPERVISORY SILENCE
switch,
a
TROUBLE SILENCE
switch, and a
RELEASE
DISCONNECT
switch. The separate visual fault indicators
are displayed within the panel for all supervised features.
Isolated relay contacts are provided for: System alarm -
DPDT, System trouble - SPDT, Predischarge/discharge -
SPDT and SPST (normally open). For information regarding
functional options. refer to the
OPERATION
section.
