BEFORE INSTALLING
This information is included as a quick reference installation guide. Refer to
the control panel installation manual for detailed system information. If the
modules will be installed in an existing operational system, inform the opera-
tor and local authority that the system will be temporarily out of service. Dis-
connect power to the control panel before installing the modules.
NOTICE: This manual should be left with the owner/user of this equipment.
GENERAL DESCRIPTION
M500X Fault Isolator Modules enable part of the communications loop to con-
tinue operating when a short circuit occurs on it. An LED indicator blinks in
the normal condition and turns on during a short circuit condition. The mod-
ule will automatically restore the entire communications loop to the normal
condition when the short circuit is removed.
COMPATIBILITY REQUIREMENTS
To ensure proper operation, these modules shall be connected to listed com-
patible system control panels only.
NOTE: The number of devices that may be installed between fault isolator
modules will vary based on the types of devices being isolated. Contact the
fire alarm control panel manufacturer for the isolator load ratings of indi-
vidual devices.
MOUNTING
M500X modules mount directly to 4˝ square electrical boxes. The box must
have a minimum depth of 2
1 /
8
".
WIRING
NOTE: All wiring must conform to applicable local codes, ordinances and
regulations.
1. Install module wiring in accordance with the job drawings and the
wiring diagram in Figure 1.
2. Secure module to electrical box (supplied by installer).
3. Terminal wire gage: 12-18 AWG.
