SEC-H-600 SECURITY CONTROLLER

Connection Overview

See Fig. 4 on page 12 to locate connectors and other components on the Security Controller.
Make connections to the Security Controller in the following order.
1. Connect the earth grounding wire to a nearby earth grounding point. See "Grounding" below for details.
2. Connect wiring to door readers, door strikes, door switches, and any other security I/O to the Security Controller.
See "Security I/O Wiring," page 15.
3. If SEC-H-R2R and/or SEC-H-RIO expansion modules are installed, make similar security I/O connections to these devices.
Refer to the appropriate mounting and wiring guide for complete details.
4. Connect communications cables. See "Communications Wiring," page 23, for ports available on the Security Controller
base unit.
5. Prepare power wiring (leave the unit powered off). See "Power Wiring," page 25, for details.
6. Connect the backup battery to the SEC-H-600 battery connector, and apply power to the unit. See "Connect the Backup
Batteries," page 26, and "Apply Power," page 27.

Grounding

Connect the supplied earth grounding wire to the ground spade lug (0.187") on the Security Controller, and to a nearby earth
ground (see Figure 6 below). Keep this wire as short as possible.

Earth Ground
In addition, connect the earth grounding lug of each expansion module to earth ground in the same manner.

Cable Types and Lengths

Recommended cable types and maximum lengths are as follows:
• RS-485 communications between the Security Controller and expansion modules, use a 24 AWG shielded, twisted pair
communication cable with low capacitance (Belden #9501 or equivalent). Maximum length is 4000 feet (1220m).
• Reader Inputs use Belden #8725 (4-pair) or #8723 (2-pair) or equivalent. Maximum length 500 feet (152m).
• Supervised Inputs and Digital Inputs use a 22 AWG shielded, twisted pair cable control cable (Belden #9461 or equivalent).
Maximum length 2000 feet (610m).
• Relay Outputs use 18 AWG unshielded instrumentation cable (Belden #9740 or equivalent), maximum length is 2000 feet
(610m). Relay outputs are rated for a maximum load of 3.0A.
• For lengths between different enclosures: Battery Backup cabling (PS-, BB): a single pair (2-conductor) shielded cable. If
wiring to expansion modules in a non-powered Security Enclosure, "Trunk power" cabling (PS-, PS+, BB), using a "triad" type
(3 conductor) shielded cable, such as Belden #1031A (14AWG), or equivalent. Maximum distances vary, see "Voltage Drop
Considerations," page 7.
