1. 24V DC emergency power input.
The DC24V power supply to be connected can be sealed lead acid batteries or similar products.
Note:
• Use an EN54-4 certified power supply.
• Please confirm that the DC24V power supply can provide the minimum operating current for the
correct operation of the SLA-500M. For example, working at maximum load (500W), the batteries must
be capable of supplying a minimum current of 27A, with which their minimum capacity must be 27Ah,
and their operating time at full load must not be less than 30 minutes.
2. Speaker zone outputs (A&B)
To connect line speakers
100 volts and 3-wire priority systems.
The output voltage is: 0 ~ 100 v.
Note:
please do a speaker circuit
check after completing the wiring.
Zones that are not connected with
speakers should be set as
disconnected. This configuration
must be done using the SF.500
software.
3. DC24V outputs for 4-wire attenuators
For installations with a four-wire attenuators system. Limited output current for each output: 0.2 A.
Note:
the output cannot exceed a total power of 28W.
4. Programmable control outputs.
These outputs will usually remain open, these outputs can be programmed with the SF-500 software to
activate or deactivate with automatic events or manual events.
5. Programmable control inputs.
These inputs will usually be kept open, these inputs can be programmed in the software SF-500 to enable or
disable them automatically or manually.
