Description
The PCA-N3060-LDM is a kind of remote annunciator that is equipped with 32 LED driver outputs. The PCA-N3060-LDM is designed to be used
for custom-made mimic panels and any devices that require zone status outputs.
The PCA-N3060-LDM activates its LED driver outputs when any initiating device is activated in the corresponding zones to inform the remotesystem operator of zone statuses. Assignment of zones for the 32 LED driver outputs can be set by the PC-based Configuration Program.
The PCA-N3060-LDM activates its built-in buzzer when any LED driver output is activated. The buzzer can be silenced by shorting the TB5(Buzzer off), so that the installer connects a typical on/off latching switch to the TB5 when installing PCA-N3060-LDM.
The LED1 on the PCA-N3060-LDM flashes while the signal transmission between the FACP and the PCA-N3060-LDM is being established.
The PCA-N3060-LDM has a test function. Pressing SW1 on PCA-N3060-LDM continuously for 5 seconds activates all the LED driver outputs fora test.
Each remote annunciator has a remote annunciator number for its identification in the system. The remote annunciator number is set by the rotaryswitches on PCA-N3060-LDM.
The system supports NFPA Class B (Style 4) wiring and the maximum length of 1.2 km (4000 ft) for annunciators. The panel supports a maximumof 30 remote annunciators.
The PCA-N3060-LDM requires 24 VDC input power to operate. The 24 VDC input power can be derived from the FACP or a remote power supply.
The internal power supply converts the 24 VDC input power to 3.3 volts for use of the internal circuitry.
