Connecting External Alarms

Overview

Each AGM-MZ includes 4, Form C, SPDT relays. The contacts are rated 2A at 250 VAC (inductive) 5A at 250

VAC (resistive). These relays are used for the connection of external alarm devices. The relays are factory

assigned to the following conditions:

Relay #1 Leak

Relay #2 Spill

Relay #3 Evacuate

Relay #4 Fault

Connection

Use the AC conduit or any of the remaining service knockouts to gain cable access to the interior of the

monitor. Locate the relay connector (page 15) and remove it from the circuit board. Secure the leads to the

connector orienting them as shown in the diagram below. When you are through securing the connections,

carefully plug the connector back onto the circuit board.
