The Ultra Sensitive Relay Module is a module that can be used in either the 12VDC or 24VDC operation mode. There’s an isolated trigger that is rated at 3VDC to 24VDC, 2mA to 16mA and can be wired as positive or negative. You can use this module when connecting an external alarm siren to a Honeywell LYNX Touch or Plus wireless alarm control panel. If you want to use this module, you’ll need to wire it directly to the LYNX Touch trigger terminal.

When wired properly, the Ultra Sensitive Relay Module can turn on power for the Honeywell auxiliary power supply. So if you program the LYNX Touch trigger to activate on any burglary alarm and stop after the bell timeout, this module trigger will automatically cause the power supply to drive power out to the external sounders as soon the LYNX Touch goes into alarm.

This Module also has (2) DPDT contacts rated at 2A, 120VAC, 28VDC. One contact is used with the positive trigger terminals while the other contact is used with the negative trigger terminals. Make sure to use a jumper when using a common power source. If using the negative trigger, you should connect the ‘POS +’ terminal to the ‘TRG+’ terminal using a jumper. If using the positive trigger, you should connect the jumper  across the ‘NEG -’ terminal and the ‘TRG -’ terminals. Additionally, you can use the output contact to make or break load circuits.
