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 activated 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 initiating zone causes the general alarm to sound again.
To set the CP-2ER to meet NFPA 12A, 13, or 2001 requirements 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 initiating 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 functions. Essentially, every supervised feature has its own separate fault indicator for ease of troubleshooting the system,
should a fault occur.
Displayed through the front cover are the usual visual indicators 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 RELEASEDISCONNECT 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.
It is critical that sufficient battery energy be provided for
either 24 hour or 60 hour system operation. All circuit
loading is fixed except for the following (See the CON-NECTION DIAGRAM on pages 4-5, also).

SERVICE SELECTION Jumper
The SERVICE SELECTION jumper is provided so that a
CP-2ER system can be operated under NFPA 72 Local or
NFPA 12A, 13 or 2001.
For NFPA 72 Local Service:
Do not place SERVICE SELECTION plug in P12 po-
sition.
NOTE: Plug may be either in P72 or not used
for 72 Local service.
Connect 5.6K ohm, 1/2W, end-of-line resistor across
TB2, terminals 3 and 4.
Connect 1K ohm, 1W, end-of-line resistor across TB2,
terminals 5 and 6.
Initiating Circuit and Local Protective Signaling Panel
Operation (Selection Plug Placed on P72).
A single zone alarm results in the following:
1. An alarm lock-in of that zone.
2. A visual alarm condition of that zone.
3. A general alarm condition of the panel which includes:
a. Change of state of fire alarm relay contacts (TB3,
terminals 4 through 9).
b. General alarm audible circuit actuated.
Since neither the discharge audible circuit nor the discharge device circuit is used, an initiation of the second
zone results in only a visual display indicating that the
second zone has alarmed.

GROUND FAULTYellow
If the ALARM SILENCE switch has been operated after
initiation of the first zone alarm, a second zone alarm results in reactivating the general alarm audible circuit, which
may then be silenced again.
For NFPA 12A, 13, or 2001 Service:
Place SERVICE SELECTION plug in P12.
Connect TB2, terminals 5 and 6 as shown in the Connection Diagram. An open circuit will cause a trouble
condition.
Initiating Circuit and Agent Release Operation (Selection Plug Placed on P12). The two initiating zones provided are arranged so that both zones (cross zoning) must
be alarmed before the agent release discharge sequence
begins.
A single zone alarm condition results in:
1. Alarm lock-in of that zone.
2. Visual alarm indication of that zone.
3. General alarm condition of panel which includes:
a. Change of state of fire alarm relay contacts.
b. General alarm audible circuit activated.
Upon initiation of both zones, the agent discharge delay
sequence begins. The discharge delay period may be
preselected by rotating the Discharge Delay Selection
switch S101 to one of the following time-in periods: 0, 5,
10, 15, 20, 25, 30, 35, 40, or 45 second delay. (Refer to
Option No. 1 below.)
As the discharge delay period begins (both zones alarmed),
and the general alarm audible circuit is de-energized, the
predischarge relay contacts (TB3, terminals 10 through
14) change state (See Option No. 4). The predischarge audible circuit, along with its associated visual indicator, is
cycled at a 2 Hz rate with a 50% duty cycle during the
selected discharge delay period. At the conclusion of the
discharge delay period, the agent release circuit is energized for approximately 1 minute, while the discharge audible is energized in a steady-on condition until either it is
silenced or the panel is reset to a non-alarm condition.
MANUAL SWITCHES
System RESET/LAMP TEST
Upon initiation of either Zone 1 or Zone 2 and/or operation of the manual DISCHARGE PRESSURE
switch, the Control Panel locks into an alarm condition. This alarm condition may only be reset by operation of the internal momentary RESET/LAMP TEST
switch. While this switch is held in the Reset position,
all indicating lamps, except POWER and charge cur-
rent operation BATTERY CHARGER are lit. It should
be noted that the Control Panel cannot be reset while
the manual DISCHARGE PRESSURE switch is in the
closed position.
ALARM SILENCE
The internal momentary ALARM SILENCE switch is
operated to silence an existing energized audible alarm
circuit. The general alarm audible circuit may be optionally silenced by momentary operation of the ALARMSILENCE switch at any time after it has become energized. The predischarge/discharge audible alarm
circuit may be optionally silenced by momentary operation of the same ALARM SILENCE switch, but only
after the selected predischarge period has timed out.
Silencing the general alarm circuit prior to operation
of the predischarge audible circuit does not inhibit the
predischarge circuit audible from its normal operation.
To silence the discharge audible circuit in this case
requires a second ALARM SILENCE switch activation. After silencing either the general alarm circuit and/
or the discharge audible circuit, both remain silenced
until the panel is reset (if alarm condition cleared).
Silence operation of either alarm circuit does not
change the state of the general alarm relay contacts.
Operation of the ALARM SILENCE switch, when the
panel is not in an alarm state, has no effect.
SUPERVISORY SILENCE
Operation of the SUPERVISORY SILENCE switch to
its Silence position results in silencing the internal supervisory buzzer when the panel is in a supervisory
condition, as indicated by the supervisory light on the
front panel. Operation of the SUPERVISORY SI-LENCE switch to its Silence position when a panel
supervisory condition does not exist causes the supervisory buzzer to operate as it does when the SU-PERVISORY SILENCE switch is in Silence position
and the panel supervisory condition is cleared to a
normal supervisory condition.
TROUBLE SILENCE
Operation of the TROUBLE SILENCE switch to its
Silence position results in silencing the internal trouble
buzzer when the panel is in a trouble condition, as
indicated by the trouble light on the front panel. Operation of the TROUBLE SILENCE switch to its Silence position when a panel trouble condition does
not exist causes the trouble buzzer to operate as it
does when the TROUBLE SILENCE switch is in Silence position and the panel trouble condition is
cleared to a normal supervisory condition.
RELEASE DISCONNECT
The RELEASE DISCONNECT switch is a normally
closed single pole switch in series with the release
circuit output. Moving the switch from its normally closed
position during a non-discharge or circuit activation
condition causes an open circuit trouble indication of
the release circuit. This prevents the associated discharge devices from activating.
Approved for Manual or Automatic alarm for the following categories: Local control unit in
accordance with NFPA 72 Local; suitable for NFPA connection; suitable also for releasing
device service in accordance with NFPA 12A, 13, and 2001. Refer to Note 3e.

2. Abort Station Operation Selection Dipswitch PS1
a. Position I Closed; II and Ill Open
When used, abort function is operational if, and only
if, one, but not two, of the associated initiating device circuits has activated. Release of the ABORT
station switch, after both initiating device circuits have
activated, results in the regular preselected discharge
delay sequence as selected on S101.
b. Position II Closed; I and Ill Open
Discharge may be aborted at any time before selected discharge delay period has expired and discharge has begun. Release of the ABORT station
switch after both initiating device circuits have activated results in continuation of the unexpired discharge delay period as selected on S101.
c. Position III Closed; I and II Open
Discharge may be aborted at any time before selected discharge delay period has expired. Release
of the ABORT station switch after both initiating de-
vice circuits have activated results in a complete discharge delay period as selected on S101.
Operation of the MANUAL DISCHARGE station re-
sults in a discharge delay period, as selected, before actual discharge begins, provided the delay selected is 30 seconds or less. When the discharge
delay selector is set for more than 30 seconds, the
MANUAL DISCHARGE switch operation gives a 30second delay period maximum.
Relay contacts change state on any of the following
conditions without any delay period.
Both initiating device circuits have activated.
MANUAL DISCHARGE station has been operated.
Normally open MANIFOLD DISCHARGE moni-
tor switch has closed.
b. Position II Closed; I Open
Relay contacts change state at conclusion of selected discharge delay period when operated by
activating both initiating device circuits, by activating manual discharge station, or by operating the
Manifold Discharge (mechanical release).
5. New York Option
To meet the requirements of the City of New York Fire
Prevention Directive 3-74 and the New York Board of
Standards and Appeals, it is necessary to modify the
CP-2ER Control Panel by deactivating the 10K ohm
resistor R174.
When R174 is not operational, certain responses of the
control unit are altered: the general alarm sounds when
the first of the two zones alarms. When the second zone
alarms, two possible sequences may be followed:
a. If the ABORT switch is not pressed.
1) Discharge audibles operate in a pulsing manner
and the general alarm circuit is silenced.
2) A 30 second discharge delay is provided by setting switch S101 at 6.
3) After the delay period, when the agent is released, the discharge audibles sound in a steady
manner.
b. If the ABORT switch is depressed before the 30
second time-in period ends.
1) The discharge audibles are silenced during the
90 second abort duration period.
NOTE: The 90 second delay period associated
with the external abort switch is provided
by others.
2) The general alarm audibles sound in a steady
manner (as if only one zone had alarmed).
3) After the 90 second abort delay period ends, the
internal 30 second discharge delay begins. At
that time the general alarm audibles silence, and
the discharge audibles begin to pulse as described in No. 1a above.
Mounting Control Units (Refer to Figure 2)
Securely fasten the control unit to a shock and vibration
free surface in a clean, dry area. It must be mounted farther than 3 feet, but less than 6 feet, from the floor. The
location should be easily visible, readily accessible for maintenance, and should allow sufficient clearance to open the
hinged front door.
INSTALLATION AND WIRING
The reliability of any system depends to a great extent on
the proper installation of the control units, detectors, associated equipment, and wiring. These instructions outline
the requirements for a satisfactory installation. Careful
completion of each detail will provide an automatic fire and
smoke detection system that is dependable and gives reliable operation.
Connection instructions are mounted inside the cover of
the CP-2ER. Additional wiring information is provided in
the manual. Any questions regarding the equipment or installation should be directed to Siemens Building Technologies, Inc. or an authorized representative; do not make
any alteration without first consulting one of the above.
Local regulations or codes generally require all wiring to,
from, and between units to be carried in 1/2-3/4 inch conduits. Knockouts are provided in the top and bottom of the
control unit. No. 18 AWG, 300V insulation, color coded
wire is recommended for the detector circuits. A larger
size may be used if desired; e.g., 16 AWG. For the power
input, audible, and release circuits, use at least 14 AWG,
300V wire.
Power Requirements
The Model CP-2ER Control Unit is designed to be operated
from a 120 VAC power source with the neutral line grounded.
The 120 VAC input powers all internal circuitry. The AC voltage may vary between the limits of 102 and 132 volts, and
the limits should not be exceeded. The CP-2ER ungrounded
leg must be connected, through a separate circuitbreaker
or fuse, directly to the power supply. No other equipment
should be supplied from this separate circuitbreaker or fuse.
Wire must be run continuously from power source to terminals in the control unit. A 24V battery provides emergency
power. Refer to the CONNECTION DIAGRAM on pages 45, for terminal connections.
Installation of Conduit and Outlet Boxes
Install outlet boxes and run conduit between boxes and
control unit. Use 4 inch octagonal boxes for ionization,
photoelectric, flame, and plug-in thermal detectors. The
depth of the boxes should be determined by the NEC requirements for the number and size of conductors used.
Do not mount boxes in direct air flow from air conditioning
or ventilating system supply registers.
The control unit, and all detectors and alarm circuit conduit, must be properly grounded. Insure that all conduit
has clean threads and makes good electrical contact between the control unit and outlet boxes.
Installation of Detector Bases
Wiring (Refer to CONNECTION DIAGRAM)
Run wire in accordance with wiring diagram. Use at least
No. 18 AWG, 300V insulation, color coded wire for the
detector circuits. Wiring between control unit and first detector base, and all subsequent detector bases, must be
continuous; no splices, wire nuts, solder, or any other type
connection is permissible. On rare occasions an exception may be necessary due to an extremely long run. In
this case, the splice must be soldered.
The wire interconnecting the detector bases is continuously supervised by a small electrical current flow through
the circuit to the end-of-line resistor (1.78K ohms) mounted
in the base of the last detector. In order to keep this supervision complete, no parallel branching of wires is permissible. Every base, except the last one, will have one set of
incoming and one set of outgoing wires.
Installing Bases
Mount end-of-line resistor between appropriate terminals
of last base on circuit, as indicated on the CONNECTIONDIAGRAM. Mount all bases to outlet boxes. Manual stations, thermal detectors, air duct detectors, etc., are to be
connected to the circuit at this time. Please refer to wiring
diagrams for the specific equipment for connection details.
Wiring Test
NOTE: It is suggested that electrical tests be conducted
jointly by the installer and the manufacturers technician or representative. Written notice is requested
15 days prior to the tests so that the services of the
technician may be scheduled.
The installation of the wiring should be checked as follows:
1.Detectors should not be in their bases. Temporary jumpers should be inserted in all bases if not already installed. Install end-of-line resistor to appropriate terminals of last detector on circuit for Class B wiring. For
Class A wiring, install the end-of-line resistor between
terminals 2 and 3 for Zone 1 and between terminals 5
and 6 for Zone 2. Wiring from bases should NOT be
connected to the Control Panel at this time.
2. Check the wiring of the detector circuit with an ohmmeter. Resistance reading between wires connected
to terminals 1 and 4 of the Control Panel or terminals 5
and 8 for the other zone should be approximately 1.8K
ohms. Short the detector lines together and megger
the combined lines to chassis and conduit. There
should be at least 10 meg resistance reading between
wires and conduit or ground.
3. Connect wires to appropriate terminals of the Model
CP-2ER.
4. Remove the temporary jumpers from the bases. The
manufacturers Service Representative will then install
the detectors and check sensitivity.
System Operation Test
CAUTION: Be sure to prevent release of the agent.
1. See that the CP-2ER control unit is in normal standby
operation.
2. To test for supervision of initiating circuit, remove the
detector connected to the last device and check that
proper trouble indicators respond in the system. Reconnect detector.
3. To test operation of initiating circuit, actuate a detector. Check that system fire indicators and alarm relay
contacts respond to the alarm.
4. Test operation of detector circuit: Activate each detector and manual station, one at a time, resetting each,
and check that detector base lamp and control unit
alarm controls operate. Each ionization detector may
be activated by blowing smoke into the chamber. The
manual station on the front panel should be checked
independently.
5. Check all basic system operational functions, particularly the operation of the time delay functions, prior to
arming the agent releasing circuits.
POWER LIMITED WIRING
Effective May 1, 1995, all power-limited fire protective signaling conductors must be separated a minimum of 1/4
inch from all of the following items located within a control
panel: electric light, power, Class 1, and non-power limited
fire protective signaling conductors .
To meet these requirements, the following guidelines mustbe observed when installing modules and wiring to this
control panel.
NOTE: If power-limited wiring is not used within this en-

TROUBLESHOOTING THE SYSTEM
Refer to OPERATION section for identity of troubles by
lamp indicator. Refer to ratings on specific circuit terminals for manual voltage readings. (See CONNECTIONDIAGRAM on pages 4-5.)
A system trouble condition causes the following panel
indications and conditions:
1. Illumination of the front panel visual trouble indicator.
2. Sounding of the internal trouble buzzer.
3. Change of state of the trouble relay contacts (TB3,
terminals 1 through 3).
When the panel is in an on battery condition, the front
panel visual trouble indicator on the internal trouble buzzer
(Items 2 and 3 above) operate in a pulsing manner with
two short On periods followed by a longer Off period. An
additional system trouble is indicated by four short On
periods followed by a longer Off period. In both these instances, the trouble relay contacts (Item 3 above) remain
in a steady change of state condition.
A system trouble may result from any of the following fault
conditions:
1. On battery condition as described above.
2. Battery fault.
a. High or low battery voltage condition.
b. Disconnected or open battery lines (includes an
