The Addressable Relay Base 6” (PAD300-RB) is combination detector base with a relay module included. The base has a locking feature for the detector that may be used or removed in the field. Once the detector is removed, the relay is accessible in the bottom of the unit. The PAD300-RB provides one form C relay output. The relay is rated for 2A at 30 VDC, and 0.5A at 125VAC. The PAD300-RB provides for separation of high voltage and non-power limited connections from the power limited Signaling Line Circuit (SLC). The PAD300- RB does not consume SLC address and does not require an auxiliary power source.
