SERIES RSS MULTI-HIGH-CANDELA STROBE APPLIANCES

(CEILING MOUNT VERSIONS)

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

GENERAL:

Series RSS Multi-High-Candela 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 utilizing Cooper
Wheelock sync protocol. The Series RSS Multi-High-Candela Strobe Appliances are UL Listed under Standard 1971 (Signaling Devices for the Hearing Impaired)
for indoor Fire Protection Service Series RSS strobes with amber, blue, green and red lens are UL Listed under Standard 1638 (Visual Signaling Appliance) for
Private Mode Emergency and General Utility Signaling. The Multi-High-Candela strobe provides two selectable light output intensities in one unit. These strobes
are listed for
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
strobes use 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 the FACP.

WARNING: PLEASE READ THESE INSTRUCTIONS CAREFULLY BEFORE USING THIS PRODUCT. FAILURE TO COMPLY WITH ANY
OF THE FOLLOWING INSTRUCTIONS, CAUTIONS AND WARNINGS COULD RESULT IN IMPROPER APPLICATION, CANDELA SETTING,
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.

SPECIFICATIONS:

ceiling mount and indoor use only, with the backboxes specified in these instructions (See wiring and mounting information). RSS models have an

NOTES:

1. Strobes will produce 1 flash per second over the "Regulated Voltage" range.

2. Clear and amber strobes meet the required light distribution patterns defined in UL 1971.

3. All models are listed by UL 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 abuse.

4. Candela ratings in Table 1 are for clear lens. Derate approximately 25% for amber lens, 55% for green lens, 70% for blue lens and 80% for red lens.

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

Table 2: Current Ratings

Maximum RMS Current Draw

UL Voltage 115cd 177cd
DC 16-33VDC 0.300 0.420
FWR 16-33VRMS 0.455 0.645

When calculating the total currents use Table 2 to determine the highest value of RMS current for an individual strobe, then multiply these values 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 to include any required
safety factors.

NOTE: The maximum number of strobes on a single notification appliance circuit shall not exceed 50.

CAUTION: These notification appliances are UL Listed as “Regulated”. They are intended to be used with FACPs whose notification circuits are UL Listed as

“Regulated.” These appliances shall not be used on UL Listed “Special Application” notification circuits unless the appliances are identified to be compatible in the
installation instructions of the FACP or unless the FACP is identified to be compatible in this instruction manual.

WARNING: THESE APPLIANCES WERE TESTED TO THE REGULATED VOLTAGE LIMITS OF 16.0-33.0 VOLTS FOR 24V MODELS USING

FILTERED DC OR UNFILTERED FULL-WAVE-RECTIFIED VOLTAGE. DO NOT APPLY VOLTAGE OUTSIDE OF THIS RANGE.

WARNING: CHECK THE MINIMUM AND MAXIMUM OUTPUT OF THE POWER SUPPLY AND STANDBY BATTERY AND SUBTRACT THE
VOLTAGE DROP FROM THE CIRCUIT WIRING RESISTANCE TO DETERMINE THE APPPLIED VOLTAGE TO THE STROBES. THE
MAXIMUM WIRE IMPEDANCE BETWEEN STROBES SHALL NOT EXCEED 35 OHMS.

CAUTION: Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off.

WARNING: MAKE SURE THAT THE TOTAL RMS CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO THE
SYSTEM’S PRIMARY AND SECONDARY POWER SOURCES, NOTIFICATION APPLICIANCE CIRCUITS, SM, DSM SYNC MODULES, OR
WHEELOCK POWER SUPPLIES DOES 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.

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.

CAUTION: Check that the installed product will have sufficient clearance and wiring room prior to installing backboxes and conduit, especially if sheathed
multiconductor cable or 3/4" conduit fittings are used.

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.

• All Strobe Appliances have in-out wiring terminals that accepts two #12 to #18 American Wire Gauge
(AWG) wires at each screw terminal. Strip leads 3/8 inches and connect to screw terminals.

• Break all in-out wire runs on supervised circuits to assure integrity of circuit supervision as shown in
Figure 2. The polarity shown in the wiring diagrams is for the operation of the appliances. The polarity
is reversed by the FACP during supervision.
