IMPORTANT: All audible and visual signaling appliances must be installed in accordance with all applicable national and local fire alarm
codes and any other required regulatory agencies.
The Siemens SL2MTS Multi-Tone Strobe appliances are designed for easy installation with a pre-wire capable mounting plate. SL2MTS
Multi-Tone Strobe is UL Listed for indoor fire protection service under Standard 1971 for Signaling Devices for the Hearing Impaired, UL
1638 for Visual Signaling Devices and Standard 464 for Audible Signaling Devices. The SL2MTS Multi-Tone is also ULC Listed under
Standard CAN/ULC-S526-16 for Visual Signaling Devices and under Standard CAN/ULC-S525-16 for Audible Signaling Devices for Fire
Alarm Systems. These models are listed for indoor use only, and for wall mount only when used with the backboxes specified in these
instructions (see mounting options).
SL2MTS Multi-Tone appliances can be field set to produce any one of eight commonly used alarm tones. Sound output can be field set to
provide either HIGH (HI) dBA or STANDARD (STD) dBA sound output level. SL2MTS Multi-Tone appliances are designed for use with
either filtered or unfiltered Full-Wave-Rectified (FWR) input voltage. All inputs are polarized for compatibility with standard reverse polarity
supervision of circuit wiring by a Fire Alarm Panel (FACP). The horn portion of the SL2MTS appliance can be field set to provide a
synchronized code 3 horn when used in conjunction with the DSC Sync Module or Siemens power supply.
The Siemens SL2 strobe meets NFPA 2016 20 millisecond light pulse duration code requirements. In addition, the Siemens SL2 product
line has been UL/ULC listed as compatible with all Fire Alarm Control Panels (FACP) and accessories that have been determined to be
compatible with Siemens ST Strobe based products including the SL, ST, SE, SEH, SET, S-HQ, STH, AS, CH, HS, MTH and Z series. The
maximum number of SL2 devices per NAC is determined by dividing the maximum current rating of the FACP NAC by the total current
rating of one SL2 device, with a maximum of 105 SL2 devices per NAC. Refer to FACP installation instructions and relevant compatibility
guides for more detail. The Siemens SL2 Series may be installed in the same notification zone and field of view with any Siemens ST, SL,
and Z series Strobe based product.
Siemens SL2 Multi-Candela Multi-Tone-Strobes can provide a synchronized strobe appliance when used in conjunction with an FACP that
incorporates the Siemens sync protocol, a Sync Module (DSC), or the Siemens Power Supply.
CAUTION: Do not change factory applied finishes. “DO NOT PAINT”.

NOTES:
1. The strobe will produce 1 flash per second over the "Regulated Voltage" range.
2. Strobe is not designed to be used on coded systems in which the applied voltage is cycled on and off.
3. The maximum number of SL2 strobes on a single notification appliance circuit shall not exceed 105.
4. These appliances are UL Listed as “Regulated”. They are intended to be used with FACPs whose notification circuits are UL Listed
as “Regulated.”
5. 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 not subjected to misuse or abuse.
When calculating the total currents: Use Table 2, 3 to determine the highest value of “RMS Current” for an individual appliance, then
multiply these values by the total number of appliances; be sure to add the currents for any other appliances powered by the same source
and include any required safety factors. Make sure that the total RMS current required required by all appliances that are connected to the
system’s PRIMARY and SECONDARY power sources, NAC circuits, DSC Sync Modules or Siemens 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. 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 applied voltage to the appliance.
CAUTION: If SL2MTS Multi-Tone appliances are operated within 15 inches of a person’s ear, they can produce a sound
pressure level that exceeds the maximum 120 dBA permitted by ADA and OSHA rules. Exposure to such sound levels can
result in damage to a person’s hearing.
ATTENTION: Si les appareils SL2MTS Multi-Tone sont utilisés à moins de 15 pouces de l’oreille d’une personne, ils peuvent
produire un niveau de pression acoustique supérieur à la vitesse maximale de 120 dBA permise par les règles de l’ADA et de
l’OSHA. L’exposition à de tels niveaux sonores peut endommager l’ouïe d’une personne.

All installations shall be in accordance with:
1) In the United States, the National Electrical Code, NFPA 70, and the National Fire Alarm and Signaling Code, NFPA 72.
2) In Canada, CSA C22.1, Canadian Electrical Code, Part I, Safety Standard for Electrical Installations, Section 32; and the Canadian
Standard for the Installation of Fire Alarm Systems - CAN/ULC-S524.
MOUNTING PROCEDURES:
1. Select a mounting option and install the backbox. SL2SPBB requires 5 1/8” spacing for surface mounting. Screws are provided.
Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product. 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.
2. Install the Mounting Plate on the backbox. Use 8-32 screws for 4” back-box or hi-lo screws for the SL2SPBB surface backbox.
3. Pre-Wire: Connect field wires to terminals on mounting plate (reference Figure 1 and 2). 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
important for stiff, heavy gauge wires and wires with thick insulation or sheathing. 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. Pre-Test: Mounting Plate contains a SHUNT between adjacent “+” terminals to facilittate testing before device is attached.
Note: Shunt will open permanently when device is installed on mounting plate.
5. Verify appliance settings are correct for your application. Settings are shown in Fig. 3-5. Factory settings are HIGH dBA, Horn, 15cd.
6. Place the SL2 appliance over the mounting plate. Engage TOP hook on mounting plate, then secure with screw at the bottom. Use
care to prevent speaker cone damage when driving the screw.
7. Align cover to the SL2MTS appliance with strobe opening over LED lens. Then, snap the cover in place .
8. To remove the appliance, insert a small flat-bladed screwdriver into the bottom opening ½” as shown in Figure 7. Then lift off grille.
Important: Do not fully back out terminal screws. Do not over tighten screws or terminals. Excessive torque may affect
operation. When using power tools, ensure the torque is set to the lowest setting available.
NOTE: Final acceptance is subject to Authorities Having Jurisdiction.
Check the installation instructions of the manufacturers of other equipment used in the system for any guidelines or restrictions on wiring
and/or locating Notification Appliance Circuits (NAC) and notification appliances. Some system communication circuits and/or audio circuits,
for example, may require special precautions to assure immunity from electrical noise (e.g. audio crosstalk).
