Alarms and Monitoring Products

Battery Operated Alarm
Local audible alarm responds to temperature rise in freezer. Alarm operates off continually recharged battery to maintain function in case of power failure. Alarm point automatically tracks control setpoint. Pre-set alarm is 80% of setpoint on -40°C and -45°C models, and 90% of setpoint on -75°C and -85°C models.

Alarm Delay Module,
Catalog No. 6903.

Alarm Delay Module
Inexpensive, easily installed and cost effective, the Revco Alarm Delay Module pays for itself by eliminating false alarms due to intermittent or transitory conditions such as lightning or brief power outages. Adjustable delay requires alarm condition to exist continuously for a determined time period before signal is released to central alarm/monitoring system or telephone dialer.

Features

• Adjustable delay period from 0.5 to 32 minutes.
• Red alarm indicator light remains flashing after transient condition is corrected; requires manual reset.
• Signals chronic alarm conditions which may indicate impending component failure; allows time for inspection or corrective maintenance if needed.

Function

• Inserts variable time interval between alarm condition detection and signal transmission.
• Accepts dry contact inputs, normally open (NO) or normally closed (NC); module can be used to invert "sense" of contacts to change incoming NO signal to NC, increasing flexibility for use with any monitoring system.
• Includes accurate digital timing circuit adjustable from 0.5, 1, 2, 4, 8, 18 or 32 minutes.
• Operates independent of line power. Built-in battery and alarm test function requires 9V battery, customer supplied.
• Low power consumption; typical battery life is 1 year.
• Isolated incoming and outgoing electrical signals.

Deluxe Electronic Remote Alarm System
User programmable to sound alarm in the event of temperature rise or power failure. Can dial up to four telephone numbers to advise of alarm condition across any telephone system which accepts pulse dialing. One system can monitor up to four (4) individual freezers or up to three (3) groups of freezers. Contact LabWorks for detailed specifications.
