Option Cards - Honeywell SEC-H-600 Installation Instructions Manual

The Security Controller and its expansion modules all have end-mounted, 6-pin, connectors that support direct chaining of
modules into assemblies. Connectors pass RS-485 communications and DC power (and battery backup) through connected
modules. Also, you can mount expansion modules remotely from the Security Controller, and use the supplied 6-position terminal
plugs to wire RS-485 and backup-battery
Fig. 1. Expansion modules are Remote 2 Reader (SEC-H-R2R), Remote I/O (SEC-H-RIO).
Expansion modules can

NOTE: Expansion modules can be plugged into, and removed from, a powered system without causing damage. However, this
is generally not recommended—especially if the system is operational.

Option Cards

The Security Controller has two (2) option slots for on-board mounting of custom option cards. Each slot has a 30-pin connector
on the Security Controller base board (see Fig. 4 on page 12). An option card typically provides additional communication ports.
NOTE: Option cards not evaluated by U.L.
Option card usage in a Security Controller is expected to be infrequent.
WARNING
All power to the Security Controller must be OFF when installing or removing option cards, or damage will occur!
Also, you must be very careful to plug an option card into its connector properly (pins aligned).
Install option cards before performing any other mounting or wiring of the Security Controller.
For installation details, refer to the installation sheet that accompanies the option card.

In most cases, backup-battery cabling requires two conductors: PS-, BB. However, if a remote expansion module is mounted in
a Security Enclosure without an integral power supply (SEC-ENC-H-3, SEC-ENC-H-1NP, SEC-ENC-H-2NP), it needs 3-con-
ductor "triad" cabling supplying 15Vdc power and backup battery (PS-, PS+, BB).
