Connecting External Alarms

Overview

The AGMSZ includes four SPDT relays whose contacts are rated 3 A at 240 VAC. These relays are used for the connection of external alarm devices that are activated when the relay is energized. The relays are factory assigned to energize under the following conditions:

Relay #1

Leak

Alarm Point 100 ppm

Relay #2

Spill

Alarm Point 300 ppm

Relay #3

Evacuate

Alarm Point 500 ppm

Relay #4

Fault

System Fault Event

Note that the alarm points of relays #1, #2, and #3 are set using the monitor’s LEAKLVL, SPILLLVL, and EVACLVL function screens (Page 16).

Connection

Use any of the service knockouts to gain cable access to the interior of the monitor. Locate the External Alarm Relay Connector (Page 8). Secure the leads from the external alarm device and its power source to the connector as shown in the diagram below.

The diagram on Page 11 shows a typical alarm device being connected to Relay 1. Note how power to this device is being tapped off the monitor’s AC input.

External Alarm Relay Connector

Each relay may be connected as normally open (NO), or normally closed (NC). The relay contacts are rated 3 A at 250 VAC.

Power for the external alarm devices may be supplied from an external power source, or from the monitor’s AC input terminals.
