Selectable Features
You can select whether the alarm output relay is in a normally-closed (the default) or normally-open position, and whether the audible
alarm should latch ON until the unit is power-cycled (default setting) OR auto-reset and return to OFF when the alarm condition clears.
To change this setting, remove the configuration cover with a very small flat-blade screwdriver or similar tool. Using tweezers, place
the jumpers in the desired position.
Note: The ENVIROMUX-SDS-CELC(P) is NOT intended to be used as a primary fire and smoke detection device.
Install Detector to Base
Connect the Detector to the base. Line the tab on the Detector up with the left end of the slot in the base. Press the Detector into the
slot so that the detector is evenly resting on the base all the way around. Then rotate the Detector clockwise approximately 1”
(2.54cm) to lock in the detector and engage the contacts on the base
.
