The SECO‑LARM SA‑025Q is a multi‑purpose programmable timer featuring adjustable timing from 1 second to 60 minutes, 12/24 VDC auto‑sensing, and an 8A Form C relay (120 VAC / 24 VDC) for controlling electric strikes, sirens, bells, and access control devices. Programming is done via DIP switches with no jumpers to cut, and the unit comes with a protective case for mounting in exposed environments.
• Operating voltage: 12/24 VDC (auto-sensing)
• Current draw: 1mA (standby), 50mA (active)
• Relay: Form C, 8A @ 120VAC / 24VDC
• Timing range: 1 second to 60 minutes (programmable via DIP switches)
• Board dimensions: 73 × 63 mm (2.875" × 2.5")
• Case dimensions: 83 × 68 × 27.5 mm (3.25" × 2.69" × 1.06")
The SA-025Q is a programmable timing relay with a 1‑second to 60‑minute range, set via DIP switches. It triggers from positive voltage, dry contact closure, or dry contact opening, with activation modes including start‑of‑cycle, end‑of‑cycle, 1‑second pulse at end, or pulse (flash) mode.
An 8A Form C relay controls door strikes, locks, and alarms, making it suitable for electric strike timing, siren duration, and delayed access functions. A built‑in reset button manually restarts the timing cycle, and an LED shows relay status.
The board (73 × 63 mm) fits inside a protective case (83 × 68 × 27.5 mm) for dust/moisture protection. It operates on auto‑sensing 12/24 VDC (1mA standby, 50mA active) with DIP switch programming — no jumpers to cut.
