INSTALLATION INSTRUCTIONS

SERIES RSSA/RSSB/RSSG/RSSR STROBE APPLIANCES

Use this product according to this instruction manual. Please keep this instruction manual for future reference.

GENERAL:

Series RSSA/RSSB/RSSG/RSSR Strobes can provide a non-synchronized strobe appliance when connected directly to a fire alarm control panel (FACP), or provide a
synchronized strobe appliance when used in conjunction with a Sync Module (SM), Dual Sync Module (DSM) or Wheelock power supplies with patented sync protocol.
Series RSS strobes with amber, blue, green and red lens are UL Listed under Standard 1638 (Visual Signaling Appliance) for Private Mode Emergency General Utility
Signaling. The RSS strobes are intended for
have an integrated strobe mounting plate (SMP) that can be mounted to a single-gang, double-gang, 4” backbox, 100mm European backbox or SHBB surface backbox.
The strobe uses a xenon flashtube with solid state circuitry enclosed in a polycarbonate lens to provide maximum visibility and reliability for effective visible signaling.
All inputs are polarized for compatibility with standard reverse polarity supervision of circuit wiring by an FACP.

WARNING: PLEASE READ THESE INSTRUCTIONS CAREFULLY. FAILURE TO COMPLY WITH ANY OF THE FOLLOWING
INSTRUCTIONS, CAUTIONS AND WARNINGS COULD RESULT IN IMPROPER APPLICATION, INSTALLATION AND/OR OPERATION OF THESE
PRODUCTS IN AN EMERGENCY SITUATION, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU
AND/OR OTHERS.

WARNING: CANDELA SETTING WILL DETERMINE THE CURRENT DRAW OF THE PRODUCT.

NOTES:

1. Candela is measured on axis. Models with MCC strobes have 4 field-selectable candela settings: 15, 30, 75, 95 cd. Models with MCCH strobes have 2 field­selectable candela settings: 115 and 177 cd. MCC and MCCH candela settings are rated for clear lens - derate approximately 25% for amber, 55% for green,
70% for blue and 80% for red lens.

2. All strobes operate from 16 to 33 volts at 1 flash/second using filtered or full-wave-rectified DC voltage.

3. Strobes with Amber Lens meet the required light distribution patterns defined in UL 1971.

4. All models are for indoor use with a temperature range of +32°F to +120°F (0°C to +49°C) and maximum humidity of 85% RH. The effect of shipping and
storage temperatures shall not adversely affect the performance of the appliance when it is stored in the original cartons and is not subjected to misuse or

VOLTAGE DROP FROM THE CIRCUIT WIRING RESISTANCE TO DETERMINE THE APPPLIED VOLTAGE TO THE STROBES.

SYSTEM’S PRIMARY AND SECONDARY POWER SOURCES, APPLIANCE CIRCUITS, SM AND DSM SYNC MODULES DO NOT EXCEED THE
POWER SOURCES’ RATED CAPACITY OR THE CURRENT RATINGS OF ANY FUSES ON THE CIRCUITS TO WHICH THESE APPLIANCES ARE
WIRED. OVERLOADING POWER SOURCES OR EXCEEDING FUSE RATINGS COULD RESULT IN LOSS OF POWER AND FAILURE TO ALERT
OCCUPANTS DURING AN EMERGENCY, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU
AND/OR OTHERS.

When calculating the total currents: Use Table 1 and 2 to determine the highest value of Average/RMS current for an individual strobe (across the expected operating
voltage range of the strobe). Then multiply the value by the total number of strobes; be sure to add the currents for any other appliances, including audible signaling
appliances, powered by the same source and include any required safety factors.

WIRING AND MOUNTING INFORMATION:

CAUTION: The following figures show the maximum number of field wires (conductors) that can enter the backbox used with each mounting option. If these

limits are exceeded, there may be insufficient space in the backbox to accommodate the field wires and stresses from the wires could damage the product.
Although the limits shown for each mounting option comply with the National Electrical Code (NEC), Cooper Wheelock recommends use of the largest backbox option

shown and the use of approved stranded field wires, whenever possible, to provide additional wiring room for easy installation and minimum stress on the product from
wiring.
