The FF345: Finding the Date Code

In this video, Michael from Alarm Grid shows you how to find the date code on an Encore FireFighter FF345 Smoke and CO Detector Takeover Module. The FF345 is a listening module for a 345 MHz security system. Upon detecting the T3 sound of an activated smoke detector or the T4 sound of an activated carbon monoxide (CO) sensor, the FF345 will transmit a 345 MHz wireless signal to a compatible alarm system. This allows the user to "takeover" existing smoke and CO detectors and integrate them with their system. This can be particularly useful for hardwired life-safety sensors, which otherwise cannot interface with alarm panels. And if the smoke detector or CO detector is part of a one-go-all-go network, where one triggered device causes all of the other sensors on the same network to activate, then a single FF345 unit can takeover an entire network of interconnected devices.

Finding the date code for an FF345 unit can be very important for determining system compatibility. The FF345 is designed to work with all Honeywell and 2GIG Systems that accept the 345 MHz frequency. But there was a batch of FF345 units that would not enroll successfully with Honeywell Systems. However, they still worked with 2GIG Systems just fine. FF345 units with a date code of 01/2020 will not enroll with Honeywell Systems. Units with a date code between 02/2020 and 08/2020 are also believed to be affected, but this has not been proven. Units with a date code of 09/2020 and onward will work with Honeywell Systems, but users may encounter a Sensor Trouble Condition with a reporting error code of E380 when clearing a smoke or CO alarm caused by an FF345. And FF345 units with a date code older than 01/2020 should work with Honeywell Systems as intended. When opening up the FF345 to check the date code, remember to remove the screws on the unit first. Then pop the cover open to access the inside of the sensor. The date code is found inside the front cover.
