Description
 
The ESL 505 module serves as an interface between the ESL 521 series low profile self-diagnostic smoke detector and a UL Listed 12/24V DC control panel. The 505 is able to interpret the 521 series trouble (CleanMe) signal and provide an output to the control panel via relays. This signal allows users to receive a message locally (visual LEDs) and remotely at the central station that the 521 needs maintenance, such as cleaning, before a false alarm occurs. The 505 also indicates a "smoke detector trouble" signal if any hardware fault is detected. Depending on how the 505 is wired, the CleanMe signal can be sent to a separate panel zone or enunciated as a general fire trouble. If shown as a general fire trouble, the diagnostic LEDs on the module can be used to determine whether the trouble is a dirty smoke detector in need of servicing or loop fault.

The 505 module's interpretation of a 521 Series CleanMe signal can be read by any alarm control panel. Another feature of the 505 Module is that it can be used to convert any ESL two-wire smoke detector to four-wire inputs on any control panel. This is especially useful on retrofit applications and for panels that do not have two-wire smoke detector capabilities.
