Siemens SL2CHC Installation Instructions

INSTALLATION INSTRUCTIONS
SL2 SERIES CHIME AND CHIME-STROBE
WITH PRE-WIRE/PRE-TEST (CEILING MOUNT)
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 SL2CHC Chime and SL2CHSC Chime-Strobe appliances are designed for easy installation with a pre-wire capable mounting
plate. All models are for 24V operation. Series SL2CHC/SL2CHSC Chime is UL Listed for indoor fire protection service under Standard
UL464 for Private Mode Audible Signal Appliances as well as ULC-S525-2016 (Audible Signaling Devices for Fire Alarm and Signaling
Systems). The SL2 Chime is designed for low current draw and versatile performance. The SL2 Chime offers a choice of 1Hz, 2Hz, coded,
or temporal code 3 (T3) operation. It has an adjustable sound level, and operates at a frequency of 890Hz. The Low Profile design
incorporates a high efficiency speaker for maximum output at minimum power, and features a sealed back construction for extra protection
and improved audibility. These models are listed for indoor use and ceiling mount with the backboxes specified in these instructions (see
mounting options). Model SL2CHC (non-strobe) may be wall or ceiling mounted.
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 Chime-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 currents: Use Table 2A and Table 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.

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. 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.
6. 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
current ratings of any fuses on the circuits to which these appliances are wired.

7. The Code 3 temporal pattern (1/2 second on, 1/2 second off, 1/2 second on, 1/2 second off, 1/2 second on, 1-1/2 off and repeat) is
0.185
specified by ANSI and NFPA 72 for standard emergency evacuation signaling. Code 3 shall be used only for fire evacuation signaling
0.274
and not for any other purpose.
8. 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.
