TC841A FlashScan® Monitor Module

The TC841A Interface Module is intended for use in Honeywell’s intelligent control panels, addressable systems, where the individual address of each module is selected using built-in rotary switches. This module allows intelligent panels to interface and monitor two-wire conventional smoke detectors. Monitor modules supervise a circuit of dry-contact input devices, such as conventional heat detectors and pull stations, or monitor and power a circuit of two-wire smoke detectors. It transmits the status (normal, open, or alarm) of one full zone of conventional detectors back to the control panel. All two-wire detectors being monitored must be UL compatible with the module.

TC841A is a standard-sized module that monitors and supervises compatible two-wire, 24 volt, smoke detectors on a Style D (Class A) or Style B (Class B) circuit. Each TC841A uses one of the available module addresses on an SLC loop. It responds to regular polls from the control panel and reports its type and the status (open/normal/short) of its Initiating Device Circuit (IDC). A flashing LED indicates that the module is in communication with the control panel.

• Supports compatible two-wire smoke detectors
• Supervises IDC wiring and connection of external power source
• High noise (EMF/RFI) immunity
• SEMS screws with clamping plates for ease of wiring
• Direct-dial entry of address: 01 - 159 on Flash Scan loops, 01 - 99 on CLIP loops
• LED flashes during normal operation, this is a programmable option
• LED latches steady to indicate alarm on command from control pane
