Smoke Detector Accessories

Smoke detectors can be installed and used without these accessories, but they do provide a bit of additional functionality if they are used in conjunction with two-wire and four-wire smokes. 

The first device on the list is the System Sensor RRS-MOD. This reversing relay module provides a polarity shift in the smoke loop to reverse it so as to set off sounders in smoke detectors that feature them, like the 2WTA-B or the 4WTA-B smoke detectors. These relays perform a polarity switch in the line to set off all sounders when one smoke is triggered. This is great for alerting people all over the building to a fire. Please note the RRS-MOD is not required when using the COSMOD modules. 

The next type of accessory that we offer for two-wire and four-wire smokes is the power supervision relay module System Sensor SYS-EOLR1. These modules are used to supervise the power on the smoke line, and if they lose power or the line is cut, then these modules create a trouble condition alerting you.

The final offering we have in this section is the SmokeSabre canned smoke product. You can use this to test your smoke detectors after installation to make sure they are functioning properly. It is advised to have canned air on hand as well, so you can blow out the smokes after testing to avoid multiple triggers.
