RH Series Rackmount Helix Installation Manual

Introduction

Product Description

The LifeSafety Power Helix RH rackmount power supplies are
a re dundant power source for use in the Access Control indus­try. 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 back­up FPO power supply. Designed to fit neatly into standard 19"

Limitations

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 sys­tem planner & installer. Please thoroughly read and under­stand the following sections before using the Helix power
supply.

Redundancy

The Helix RH series of power supplies adds a layer of redun­dancy over the typical FPO power supply. Only the FPO power
supply is redundant - any distribution in the system is not re­dundant. 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.

equipment racks, the streamlined cabinetry and exceptional
features combine to significantly reduce installation and ser­vice 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.

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 opera­tion. A battery should not be connected to FPO1 - this is to
prevent cycling between FPO1 and FPO2 during battery dis­charge on loss of AC.

Fault Contacts

The fault contacts of BOTH FPO power supplies must be moni­tored to annunciate failure of either power supply. The fault
contacts may either be monitored separately or series/paral­leled as needed for a common fault indication. Use of a Netlink
network monitoring module is also highly recommended.

HELIX RH Series

The Helix RH Series of single voltage DC power supplies pro­vide 12 or 24 VDC power at 75W, 150W and 250W of total
power. They are available with 8 or 16 outputs and the capabili­ty 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.

Installation and Operation

Section 1 – Installation

The following pages cover the installation of the Helix RH Series rack-mountable power supplies.

1.1 Mounting the Rack Mount Supply into a Standard 19" Rack

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 en­closure. (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.
