CDD-38-30008
TIME DELAY RELAY
1.8 TO 180 SEC.
CONTACTS 10 AMP.
240 VAC RESISTIVE
The Tyco Potter & Brumfield CDD-38-30008 is a time delay relay designed to introduce a precisely adjustable delay into control and alarm circuit logic. With a timing range of 1.8 to 180 seconds, 10A contacts, and a 240VAC resistive rating, this relay provides reliable timed switching for fire alarm and detection systems onboard. Within a marine Fire Alarm System, time delay relays serve a critical operational role — managing sequential activation, suppressing nuisance alarms, and ensuring controlled response intervals during detection and suppression sequences. Correct relay function is integral to system integrity and crew safety.
Key Features
✓ Adjustable time delay range of 1.8 to 180 seconds, allowing flexible configuration to match system timing requirements.
✓ Contact rating of 10A at 240VAC resistive, as specified in the original product data; further electrical ratings subject to confirmation against the original datasheet.
✓ Designed for integration within fire alarm control and detection panel circuits where timed relay outputs are required for sequential or delayed activation logic.
✓ Compact relay format suitable for panel-mount installation in control room enclosures or fire alarm cabinet assemblies — installation environment and mounting specifics depend on vessel configuration.
✓ Replacement of time delay relays should be carried out using the correct part reference to maintain system calibration and compliance with the vessel’s fire detection system design.
Marine Applications
✓ Fire alarm and detection systems aboard commercial cargo vessels, tankers, and passenger ships requiring timed relay control logic.
✓ Engine room fire suppression pre-discharge warning circuits where a delay interval is required before agent release.
✓ Accommodation and machinery space alarm panels integrating time delay functions to avoid spurious activations.
✓ Integrated bridge and safety management systems where relay outputs are coordinated with fire and gas detection sequences.
✓ Offshore platforms, ferry operators, and naval auxiliary vessels utilising Tyco or compatible fire alarm panel infrastructure.
