INSTALLATION INSTRUCTIONS

SERIES SM AND SMX SYNCHRONIZATION (SYNC) MODULE

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

GENERAL:

Wheelock’s Sync Modules (Series SM) are uniquely designed to accept two independent strobe and audible inputs and convert to a single output that connects to Wheelock’s Series AS and NS appliances. When interfaced with the sync module, the audible strobes produce the synchronized code 3 horn and synchronized strobe upon actuation. The audible portion of the AS and NS can be controlled independently from the strobe, using only a 2-wire alarm circuit. They are the ideal choice for alarm systems where an audible silencing feature is required during an alarm condition. The SM is UL Listed under Standard 1971 (Emergency Appliances for the Hearing Impaired) for indoor use Fire Protective Service. All inputs are polarized for compatibility with standard reverse polarity supervision of circuit wiring by a Fire Alarm Control Panel (FACP).

The table below shows the additional Wheelock products that can be used with the SM Sync Modules.

WARNING: MAKE SURE THAT THE TOTAL CURRENT REQUIRED BY ALL APPLIANCES THAT ARE

CONNECTED TO A SYNC CONTROL MODULE DOES NOT EXCEED 3.0A OR EXCEED THE RATING OF THE FIRE

ALARM CONTROL PANEL’S PRIMARY AND SECONDARY POWER SOURCES AND NAC CIRCUITS.

OVERLOADING THESE SOURCES 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 average, peak or inrush currents: Use Table 3 to determine the highest value of “Rated Average Current” for an individual strobe (across the expected operating voltage range of the strobe) to determine the highest value of “Rated Inrush

Current” or “Rated Peak Current” (whichever is higher) of an individual strobe (across the expected 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.

If the inrush current or peak current exceeds the power supplies’ inrush capacity, the output voltage provided by the power supplies may drop below the listed voltage range of the appliances connected to the supply and the voltage may not recover in some types of power supplies. For example, an auxiliary power supply that lacks filtering at its output stage (either via lack of capacitance and/or lack of battery backup across the output) may exhibit this characteristic.

WIRING INFORMATION:

NOTE: Non-sync appliances can be installed before or after an SM or DSM. If the non-sync appliance requires audible silence, four wire connection is necessary with the strobe circuit connected before the SM or DSM NAC circuit, and the audible leads connected to a silenceable NAC circuit from the FACP.

CAUTION: Power Supply may be used in conjunction with the SM Sync Modules ONLY in the order shown in Figure 1. Only one SM Sync Module shall be allowed on a signaling circuit. Do not connect the Power Supply to the signaling circuit after the one

SM Sync Module. Exception: The Wheelock PS-12/24-8 Power Supply can be connected either before or after the SM Sync Module.

Refer to Power Supply instruction manuals for proper application or installation.

Figure 5.

Sync Modules have in -out wiring terminals that accepts two #12 to #18 AWG wires at each screw terminal. Strip leads 3/8 inches for connection to screw terminals. Break all in-out wire runs on supervised circuits to assure integrity of circuit supervision shown in

Figure 5. The polarity shown in the wiring diagrams is for the operation of the appliances. The polarity is reversed by the FACP during supervision.

GROUNDING: Install the appliance to a grounded backbox (Per NFPA 70, the National Electrical Code) using the lockwashers provided in hardware bag under the head of each mounting screw for the appliance.

APPLICATION NOTES:

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.

1. Mountin g hardware is supplied with each product.

2. Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product.

3. When terminating field wires, do not use more lead length than required. Excess lead length could result in insufficient wiring space for the signaling appliance.

4. Use care and proper techniques to position the field wires in the backbox so that they use minimum space and produce minimum stress on the product. This is especially import ant for stiff, heavy gauge wires and wires with thick insulation or sheathing.

5. Do not pass additional wires (used for other than the signaling appliance) through the backbox. Such additional wires could result in insufficient wiring space for the signaling appliance.

6. All models are UL Listed for indoor use only with a temperature range of +32

°

F to +120

°
