Fire Alarm Interface Installation / Patch Cable Installation
Fire Alarm Interface Installation
The Fire Alarm Interface allows a relay closure to be connected to the SMA master clock that allows the user to interface the existing fire alarm
with the Sapling SBT 3000 series digital clocks.
Patch Cable Installation
When a relay closure occurs on pins 8 and 9, “FirE” will display on the digital slave clocks connected using RS485 or 2-wire digital communication.
1) Connect a patch cable to the RJ45 port on the SMA Master Clock as shown in Fig 1.1.
2) Connect the other end of the patch cable to an Ethernet jack connected to the network.
