Relays & Timers
Relays and timers are essential components in fire alarm and life safety systems, providing control, flexibility, and intelligent interfacing between devices. At Firesense, we supply a wide selection of fire-rated relays, timer modules, interfaces, and control units designed for professional installations where reliable switching and timing functions are critical.
Our range includes multi-purpose relay units, programmable timer relays, and input/output interfaces that allow fire alarm systems to integrate with auxiliary equipment such as door holders, HVAC controls, access systems, or visual and audible indicators. These devices play a vital role in ensuring the system reacts appropriately during an alarm condition or specific operational event.
Many of the relay units we offer are DIN-rail or PCB-mounted, suitable for fitting within control panels or enclosures. They support volt-free changeover contacts and offer selectable delays, latch functions, or pulse output options. This makes them suitable for a wide range of applications including delayed sounder activation, alarm zoning, fire door release, and triggering of third-party equipment.
Among the popular products in our range are:
- C-TEC NC943B Universal Call Controller Relay – used for call system integration and general control purposes.
- C-TEC PDA1271 and PDA1272 Delay Timer Modules – ideal for use where a timed delay is needed before activating outputs or relays.
- RTS-SMLC & RTS-SMLC-230 – versatile relay timer switches offering adjustable delays and easy DIN-rail installation.
- Vimpex VTM-GB 0-60 Second Timer – compact and configurable, used to delay outputs such as sounders or interface relays.
Each unit is designed for long-term reliability and compatibility with standard fire and safety system wiring and voltages. Options are available for 12V, 24V, and 230V operation, giving installers the flexibility to specify the right unit for the application.
Whether you’re looking to manage alarm output delays, control devices during fire conditions, or interface with other safety systems, Firesense has a relay or timer solution to suit. We offer same-day dispatch on orders placed before 2.30pm, and trade counter collection is also available for added convenience.
If you need help selecting the correct relay or timer module for your system, our team is on hand to provide expert advice and product support. Contact Firesense today to discuss your requirements.
