Yes, the SSM is UL1971 Approved for hearing impaired applications.
How to Install the SSM Strobe Synchronization Module
This guide provides step-by-step instructions for installing and wiring the SSM Strobe Synchronization Module to ensure proper synchronization of strobe lights.
Estimated time: 45m
Tools needed:
Screwdriver, Wire strippers, Multimeter
Supplies needed:
Mounting screws, Terminal connectors
- Mount the sync module
Secure the SSM module to a two gang, 2-inch deep, grounded back box using the supplied hardware. Ensure that the module is level and firmly attached.
- Connect the power supply
Strip 3/8-inch of insulation from the wires. Connect the strobe signal output from the control panel to the terminals marked 24 Vdc in at J1. Connect the Signal Positive (+) to the '+' terminal and the Signal Negative (–) to the '–' terminal.
- Wire the strobes
Connect the red (+IN) lead of strobe #1 to the '+' terminal and the red (+OUT) lead to the red (+IN) lead of strobe #2. Connect the black (-IN) lead of strobe #1 to the '–' terminal of 24 Vdc out at J3, and connect the black (-OUT) lead to the (-IN) black lead of strobe #2.
- Verify connections
Use a multimeter to check the connections for proper voltage and continuity. Ensure that the total peak operating current does not exceed the ratings specified for the SSM module.
- Test the system
After installation, turn on the power and test the system to ensure that all strobes are synchronized and functioning properly. Do not stare directly at the lights during testing.
