The Siemens TXR-320 is a conventional, dual-hazard releasing fire alarm control panel for sprinkler and agent-release systems. Specifically, it supports deluge sprinkler, pre-action sprinkler, and Sinorix-engineered agent-release applications. In addition, the panel is UL 864 9th Edition Listed and CSFM Approved (file #7165-0067:0270).
How the Siemens TXR-320 is configured
First, the technician selects one of 13 pre-configured operating modes from the front panel. Then, basic settings can be tuned without a laptop using the optional TCFG-300 configuration tool. As a result, common deluge, pre-action, and agent-release jobs go live without PC-based programming.
Verified inputs and outputs
- Six (6) Class B (Style B) initiating input circuits
- Inputs 1-4: configurable as Alarm (latching or non-latching), Supervisory, or Agent Release Flow
- Inputs 5-6: configurable as Manual Release, Abort Input, or Abort Release Combination Input
- Four (4) Class B (Style Y) notification appliance output circuits
- NAC power: 5 A max total
- Output current capacity: 1.7 A maximum per circuit
- Optional Class A (Style D / Style Z) wiring via TICAC and TOCAC converter modules
Releasing functionality and abort timers
The TXR-320 supports single-hazard and dual-hazard releasing configurations. Furthermore, abort timer options include Standard UL delay, IRL delay, NYC delay, and local AHJ delay. Cross-zone monitoring is available — Inputs 1 and 2 act on Output 3, while Inputs 3 and 4 act on Output 4.
User interface and access control
A two-line 20-character backlit LCD displays alarm, supervisory, and trouble events. In addition, membrane buttons handle Acknowledge, Alarm Silence, and System Reset. For security, maintenance and technician levels are password-protected.
Optional modules
The TXR-320 accepts several panel-mounted accessories. Specifically, TRM-306 adds six Form C relays (28 VDC, 1 A resistive) and TSRM-312 adds twelve Form C relays at the same rating. Also, TPR-300 provides city-tie reverse-polarity outputs for municipal box and off-premises signaling per NFPA requirements. For remote annunciation, the TRAM-208 offers 8 points of LED annunciation with system status and control buttons.
Compatible conventional detectors
The TXR-320 is compatibility-listed with Siemens Models HI121 (heat), OH121 (multi-criteria), and OP121 (photoelectric) detectors. Furthermore, each of these detectors uses the standard Siemens DB-11 base. The panel ships complete with a key-lock door enclosure and battery space for up to 12 Ah batteries.
