The SD-TRM is a magnet-operated remote test and reset station for SuperDuct duct smoke detectors. Hold a test magnet to the marked target on the plate and the detector tests or resets, with no keyswitch to manage and no moving parts in the wall plate to wear out or jam.

Built for the commercial fire installer

Duct detectors end up on rooftop units and above hard ceilings, so annual testing and post-alarm resets mean roof access or a lift unless the function is brought down to a wall. The SD-TRM does that with a sealed plate and a magnet, which suits sites where keys get lost or where several technicians need access without key control. The red alarm LED reports detector status at a glance.

It fits a standard North American 1-gang box or a 4-inch square box with a 1-gang cover, and takes ordinary 12 to 22 AWG wiring. Listed by UL, ULC, FDNY, CB, and CC.

Key features

  • Magnetic operation: no keyswitch and no moving parts in the plate, operated with a test magnet
  • Remote alarm LED: red alarm indicator shows detector status from the wall
  • Standard box mounting: 1-gang box, or a 4-inch square box 1-1/2 inches deep with a 1-gang cover
  • Sealed plate: nothing to pick or force, useful in public corridors
  • Wide temperature range: rated 32 to 131 F for mechanical rooms and unconditioned spaces

System requirements

For use with SuperDuct conventional two-wire and Signature duct smoke detectors. Requires a test magnet to operate; order the SD-MAG test magnet kit if the site does not already have one. Wire with 12 to 22 AWG, keeping resistance under 10 ohms per wire. An end-of-line resistor is required on the last controller only, with its value set by the fire alarm control panel. Do not loop wires under the terminals. For a keyed station instead, order the SD-TRK.

FAQs

What is the difference between the SD-TRM and the SD-TRK?
How they are operated. The SD-TRM is magnetic, worked with a test magnet and no keyswitch. The SD-TRK is keyed, restricting operation to staff with the key. The SD-TRK also has a higher switch rating: 125 VDC at 4 A versus 200 VDC at 0.5 A.
Do I need a magnet to use the SD-TRM?
Yes. The station is operated by holding a test magnet to the marked target on the plate. Order the SD-MAG test magnet kit if the site does not already have one.
Which duct detectors does the SD-TRM work with?
SuperDuct conventional two-wire duct smoke detectors and Signature duct smoke detectors.
What box does this mount to?
A North American 1-gang box, or a standard 4-inch square box 1-1/2 inches deep fitted with a 1-gang cover.
Where does the end-of-line resistor go?
On the last controller only. The value is determined by the fire alarm control panel. Do not loop wires under the terminals: break the wire run so connections remain supervised.
