Connecting A Searchpoint Optima Plus Or Searchline; Excel - Honeywell XNX Quick Start Manual

2�8�1 Connecting a Searchpoint Optima Plus or Searchline

Excel

Connections from the Searchpoint Optima Plus or Searchline Excel to the XNX
are made via two pluggable terminal blocks allowing ease of installation and
service (see Figure 19). HA recommends an 8" (203mm) service length for wiring
be maintained.
The Searchpoint Optima Plus or Searchline Excel can be supplied in either Sink
or Source mode operation and is typically labeled on the white wire exiting the
Searchpoint Optima Plus or Searchline Excel. Use the table in Figure 19 to set S3
and S4 to the SAME output type that appears on the wire tag of the IR device.
Note:
A second, black-handled screwdriver is included for use on terminal blocks 2
and 4. This tool is smaller than the magnetic wand and is designed to fit into
the terminal connections on TB2 and TB4.
For more information see the Searchpoint Optima Plus Operating Instructions
(2104M0508) or the Searchline Excel Technical Manual (2104M0506).
Attaching the Searchpoint Optima Plus to the XNX Universal Transmitter
For M25 entries, insert the seal (P/N 1226-0410) into the proper cable/conduit
opening then thread the lock nut (P/N 1226-0409) onto the Optima to the end of
the threads. Thread the Optima body into the XNX until the seal compresses and/
or Optima bottoms out. Reverse until the semi-circular pattern of holes on the front
of the weather protection are on the bottom (see below) then tighten the lock nut
to the XNX body.
The 3/4" NPT entries do not require the seal and locknut, the form of the threads
provide positive locking and sealing.
Note:
When attaching the Searchpoint Optima Plus, be sure to coat the threads
with an anti-seize compound to prevent corrosion.
