NOTICE
• The interface on the remote alarm monitoring system is intended for connection to the end user’s central alarm
system(s) that uses normally-open or normally-closed dry contacts.
• If an external power supply exceeding 30 V (RMS) or 60 V (DC) is connected to the remote alarm monitoring system’s
circuit, the remote alarm will not function properly; may be damaged; or may result in injury to the user.
