The LifeSafety Power Helix RH rackmount power supplies are
a redundant power source for use in the Access Control indus-
try. Two identical FPO power supplies are combined in a single
enclosure with the Helix module to provide a single output
voltage. In the event of a failure of the main power source, the
Helix module will automatically switch the output to the back-
up FPO power supply. Designed to fit neatly into standard 19"
equipment racks, the streamlined cabinetry and exceptional
features combine to significantly reduce installation and ser-
vice costs. Features include removable terminal strips for field
wiring, input and output surge suppression, automotive blade
fuses for improved reliability, a front removable chassis face
plate for serviceability and is enclosed in a 16 gauge steel 2U
rack mount chassis.
The Helix RH Series of single voltage DC power supplies pro-
vide 12 or 24 VDC power at 75W, 150W and 250W of total
power. They are available with 8 or 16 outputs and the capabili-
ty of remote monitoring of the supply's parameters via internet
or intranet connection. Ideal for Access Control, CCTV, Burglar,
Fire, or Mass Notification applications. Helix provides added
system integrity by automatically switching to the backup
power supply in the event of a problem with the primary power
supply. Each output is fused at 3A, but may be increased up to
7.5A by the installer for powering high power devices.
i Due to the nature of this product and its intended ap-
plications, the limitations and conditions of installation of
the Helix power supply must be fully understood by the sys-
tem planner & installer. Please thoroughly read and under-
stand the following sections before using the Helix power
supply.
Redundancy
The Helix RH series of power supplies adds a layer of redun-
dancy over the typical FPO power supply. Only the FPO power
supply is redundant - any distribution in the system is not re-
dundant. Also, the Helix cannot overcome any problems in the
field wiring or load devices - if a short circuit shuts down the
main supply, the backup supply will also be shut down by this
short circuit.
Primary AC Connection
Both FPO power supplies must be powered from the same AC
branch circuit. Powering the two internal FPO power supplies
from different branch circuits could lead to possible improper
operation and loss of output voltage.
Backup Battery
FPO2 must have battery backup connected for proper opera-
tion. A battery should not be connected to FPO1 - this is to
prevent cycling between FPO1 and FPO2 during battery dis-
charge on loss of AC.
Fault Contacts
The fault contacts of BOTH FPO power supplies must be moni-
tored to annunciate failure of either power supply. The fault
contacts may either be monitored separately or series/paral-
leled as needed for a common fault indication. Use of a Netlink
network monitoring module is also highly recommended.

Installation and Operation
Use the following procedure when mounting an RH series
supply into a standard EIA 19" equipment rack.
1. Ensure any internal configuration (voltage selection, fault
detection settings, etc) are complete before mounting.
See Section 1.3 of this manual for more information.
2. Securely mount the included ears to the enclosure sides
using the eight included 6-32 countersunk screws (four
per ear).
3. Locate the rack-mounting holes in the ears of the en-
closure. (Figure 1)
4. Slide the enclosure into an open 2U location in the rack
5. Center the enclosure in the rack and secure with the
four 10-32 x 3/4" screws provided.
NOTE: Use rails or other appropriate support for heavy
enclosures. Keep heavier components near the bottom of
the rack to reduce the risk of toppling of a top-heavy rack.

Installation and Operation
The following are basic descriptions. Refer to the appropriate section for more detailed information. Note that the front and
back panels may appear different based on the configuration of your system.
1Main AC Power Switch / Circuit Breaker - This is the
main AC power switch for the enclosure. This switch lights
when power is on and also has a built-in circuit breaker
rated at 8A. If the circuit breaker trips, reset it by cycling
the switch to off then back to on.
2AC Line Input - This is the connector for the AC line
cord. Plug the included computer-style line cord into this
connector. Connect the other end of the cord to the power
strip inside the rack or another suitable AC power receptacle.
IHelix RH models are preconfigured for either 120VAC
or 230VAC input - Verify the input voltage for the model
being installed prior to applying AC power.
3Ethernet Connection (Optional) - This is the RJ45 jack
for the network connection for the internal NetLink board (if
present). The ethernet cable is plugged into this jack. This
jack is only present on Helix series power supplies with a
model number ending in "N". See the corresponding Net-
Link manual for more information.
4Distributed Outputs - These are the redundant zone
outputs. The Helix Series is available with 8 or 16 outputs.
The output numbers correspond with the output zone num-
bers on the front panel. Bulk Output models without distri-
bution will not have these terminals.
IHelix RH models are preconfigured for either 12VDC
or 24VDC output - Verify the output voltage for the model
being installed prior to connecting field wiring.
5Power Supply Connections - These are the connections
to the internal FPO Power Supplies. Only the following con-
nections should be made - leave all other terminals discon-
nected:
Power Supply 1
ACF & SF - These are the AC and System Fault outputs for
FPO1. From the factory these are set to provide a closed
connection when there is no fault. These fault connections
must be monitored along with the fault outputs of FPO2 to
ensure notification of problems with either FPO power supply.
Power Supply 2
Bat (±) - This is where the battery connection is made. The
voltage of the battery set must match the voltage of the
Helix model being installed. Do not connect a battery to the
Bat +/- terminals of Power Supply 1.
ACF & SF -These are the AC and System Fault outputs for
FPO2. From the factory these are set to provide a closed
connection when there is no fault. These fault connections
must be monitored along with the fault outputs of FPO1
to ensure notification of problems with either FPO power
supply.

Installation and Operation
Configuration internal to the rack mount enclosure is re-
quired on RH series power supplies prior to installation into
a rack. Ensure all power is disconnected before performing
this initial configuration.
1.3.1 Removing the Top Cover of the Enclosure
Use the following steps to remove the top cover of the rack-
mount enclosure and gain access to the configurable settings.
(Figure 2)
1. Lay the enclosure flat on its bottom surface
2. Remove and retain the six philips head screws from
the top cover
3. Remove the top cover and set it aside in a safe location
When configuration is complete, reverse the removal pro-
cedure to replace the cover.

1.3.2 Enabling or Disabling Battery Presence Detection
Each FPO power supply may be set to detect a missing bat-
tery set. If required, battery presence detection should only
be enabled on the secondary FPO, as the primary FPO does
not receive a battery set. To enable battery presence detec-
tion, place the BATDET jumper ON. To disable battery pres-
ence detection, remove the BATDET jumper, or place it on
only one pin. (See #2 in Figure 3)
1.3.3 Enabling or Disabling Earth Ground Detection
Each FPO power supply is able to detect earth ground
faults. To enable earth ground fault detection, place the
EARTH GND DET jumper ON. To disable earth ground fault
detection, remove the EARTH GND DET jumper or place it
on only one pin. (See #1 in Figure 3)
IOnly one device in a system should have earth ground
fault detection enabled or conflicts may occur. In addition,
only ONE FPO power supply in a HELIX RH system should
have earth ground fault detection enabled or a conflict may
occur.
1.3.4 Changing the Operation of the Fault Contact Output
From the factory, RH series supplies are shipped with a
normally open fault contact operation (relay contact closed
until a fault occurs).
This operation may be switched to a normally closed con-
tact (relay contact open until a fault occurs) by moving a
wire on each fault contact.
To switch from the default NO fault contact to a NC contact,
locate the fault output terminal strip on the FPO power sup-
ply. Identify the contact you want to change (SYS FLT or AC
FLT), loosen the terminal, remove the wire from the NO ter-
minal, move it to the NC terminal, and tighten the terminal.
IThis must be done on both HELIX FPO power supplies.
