Siemens SL2 Series Installation Instructions

INSTALLATION INSTRUCTIONS
SL2 SERIES STROBE WITH PRE-WIRE/PRE-TEST
CEILING MOUNT (BLUE LENS)
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 SL2STC-B multi-candela strobes are designed for easy installation with a pre-wire capable mounting plate. All models are
for 24V operation. SL2STC-B is designed for ceiling mounting only.
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 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".
ATTENTION: Ne pas modifiez les finitions appliquées en usine. "NE PAS PEINTURER"
IMPORTANT: PLEASE READ THESE INSTRUCTIONS CAREFULLY. FAILURE TO COMPLY WITH ANY OF THE FOLLOWING
INSTRUCTIONS 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.

When calculating the total strobe current: Use Table 2 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.

NOTES:
1. Strobe settings will determine the current draw of the product.
2. The strobe will produce 1 flash per second over the "Regulated Voltage" range.
3. Strobe is not designed to be used on coded systems in which the applied voltage is cycled on and off.
4. The maximum number of SL2 strobes on a single notification appliance circuit shall not exceed 105.
5. Blue strobes are not to be used as a Visual Public Mode alarm notification appliance.
6. These appliances are UL Listed as "Regulated". They are intended to be used with FACPs whose notification circuits are UL Listed
as "Regulated."
7. These appliances were tested to the regulated voltage limits of 16.0-33.0 Volts. Do not apply voltage outside of this range. 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 strobes. The max wire impedance between strobes shall not exceed 35 ohms.
8. Make sure that the total RMS current required by all appliances that are connected to the system's primary and secondary power
sources, notification appliance circuits, sync modules, or power supplies does not exceed the power sources rated capacity or the
65cd
current ratings of any fuses on the circuits to which these appliances are wired.
0.185
9. The effect of shipping and storage temperatures shall not adversely affect the performance of the appliance when it is stored in the
0.274
original cartons and not subjected to misuse or abuse.

1. This model has in-out wiring terminals that accept #12 to #18 American Wire Gauge (AWG) wires
at each screw terminal. Strip leads 3/8 inches and connect to screw terminals.
2. 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 operation of the appliances. The polarity
is reversed by the FACP during supervision.
