How to Determine Detector Device Compatibility
If doing a control panel retrofit of an existing system and want to know if the panel is compatible with the 2-wire smoke detectors currently installed, refer to the Fire-Lite Device Compatibility Document. If the detectors or devices are not listed in this document, it is recommended that they be replaced.

Innovair Duct Detectors Show a Tamper Fault
Innovair duct detectors may show a tamper fault even with the cover on. For instance, the cover of the duct detector is only secured to the housing on one half of the cover. When the duct detector is mounted and there is some flex in the housing, the unsecured side of the cover separates causing the tamper to activate. System Sensor is addressing the problem and will be adding more screws to the cover. To solve the problem with currently installed duct detectors, place a screw at the end of the post that presses down on the tamper switch.
Duct Detectors DH100, D350, D350-RPL Trouble
Duct detectors (DH100, D350, D350-RPL, etc.) will cause a control panel trouble exactly 20 minutes after a control panel reset if the cover is removed for more than 20 minutes.
DH400ACDA Duct Detector not Functioning
The current that the auxiliary relay contacts are switching must be at least 500 mA. If the switching less current, the contacts may chatter or not function.
Installed beam detector displays "Dirty 1" on the FACP
As the beam detector was being manually aligned the chamber values were being calculated by the FACP. As a result, the chamber values are now out of tolerance.
To fix:
• Change the beam detector address to a new unused address.
• Delete the old beam detector address.
• Autoprogram the control panel.
How does the B501BHT Sounder Base for addressable detectors work?
This sounder (T = Temporal pattern sounder), built into an addressable detector base, is activated in one of two ways.
- Once the control panel has determined that an alarm condition exists, it latches the LED of the addressable detector head, which will further activate the sounder in the base.
MS-9200UDLS - When the alarmed detector is programmed for Alarm Verification, the sounder is activated immediately.
MS-9600/ MS-9600LS - When the alarmed detector has been programmed for Alarm Verification, the sounder is activated only after an affirmative verification of the alarm signal by the control panel.
- The second method is used to activate a number of sounders with one alarm initiation. Activation occurs by reversing the 24 VDC power supplied to the sounder, using two sets of alarm contacts from the control panel or module.
Mounting Note: The B501BHT Sounder Base is the regular/classic profile and can be used with the SD350SD350T, CP350 and H350, which are low-profile devices. This combination requires the F110 retrofit flange.
