Bosch D344-RL — remote indicator plate kit for Bosch duct smoke housings and beam smoke detectors.
When a duct detector sits in a plenum or above a ceiling where its own LED cannot be seen, the D344-RL brings the alarm indication and the sensitivity test points down to an accessible plate. A technician reads sensitivity there with a volt-ohm meter; the voltage falls as dust builds in the chamber.
- Serves D340, D341, D342 and legacy D343 duct housings, the D285DH smoke head, and D296/D297 beam detectors
- Ships as plate, five-wire harness, hardware pack and literature pack
- Operating voltage 10 to 32 VDC, 24 VDC nominal
- With D340 family housings, 20 mA alarm, 10 mA standby at 24 VDC
- With beam detectors, 15 mA alarm, 5 mA standby at 24 VDC
- Run up to 500 ft from the detector at 18 AWG, 200 ft at 22 AWG
- Surface mounts to a single-gang or wire-mold box, or flush; UL 268 cULus
The supplied harness connects the power card in a D340, D341, D342 or D343 housing to the plate, and is not used with the D296 or D297 beam detectors. This is an accessory: the housing and detector head are ordered separately.
