Product Overview:

Eliminate nuisance and transient condition alarms with the ADM-215 Remote Alarm Delay Module. The ADM-215 allows a technician to set a time that must elapse, with the alarm condition continuously present, before the alarm signal is relayed to a central monitoring system or dialer. By selecting the optimum alarm delay, transitory fluctuations in power, temperature (for example, due to loading or unloading a ULT freezer), and other monitored parameters are filtered out and nuisance alarms are eliminated.

The ADM-215 Remote Alarm Delay Module is compatible with Hampshire Controls’ Tº Sentry Model 140 Temperature Monitor/Alarms, MPS Monitor/Alarms, LD-215 Liquid Nitrogen Level Detector/Alarm, and CA5000-C Liquid CO2 and CA5000-N Liquid Nitrogen ULT Freezer Backup Systems. Connect the relay outputs from these systems to the ADM-215 to eliminate nuisance and transient condition alarms.

The ADM-215 Remote Alarm Delay Module serves as a valuable interface between equipment with relay output and building or laboratory supervisory systems. Because it accepts either normally open (NO) or normally closed (NO) dry contact inputs, the ADM-215 is compatible with virtually any alarm system.
