The TFB-180SA and TFB-180BSA are advanced fire detection devices, each integrating a base for an addressable detector with either an addressable horn (TFB-180SA) or an addressable strobe horn (TFB-180BSA). These devices are designed to enhance fire safety systems by combining detection and alarm functionalities in a single unit. They are compatible with Telefire's addressable detector series, including the TFO-480A, TFH-280A, and TPH-482A.
Function Description:
The primary function of these devices is to provide both fire detection capabilities (when paired with a compatible detector) and audible/visual alarm signals. The TFB-180SA features an integrated horn for audible alerts, while the TFB-180BSA includes both a horn and a strobe light for combined audible and visual warnings. This integration simplifies installation and wiring, making them suitable for various fire safety applications.
In an alarm state, the horn and/or strobe light activate to alert occupants. The operation of the horn and strobe light can be silenced by pressing the "Horn Silence" button on the fire detection panel. For the TFB-180BSA, setting the panel to "Silenced Horns" will disable the horn, but the strobe light will continue to operate until the "Respond" button is pressed on the panel.

- Supplied by the operation panel or addressable output assembly: 24 Vdc
- Current Consumption (TFB-180SA):
- Device line: 180 µA (quiescent state), 2 mA (alarm state)
- 24Vdc power source: 10 mA (quiescent state), 22 mA (alarm state)

- Wiring:
- Communication line: 2-strand wire of 12-20AWG (0.5-3.3mm² section area). Twisted pair recommended for connections between different buildings.
- Maximum cable length varies by AWG, e.g., 570m for 20AWG (0.518mm²), up to 3,625m for 12AWG (3.31mm²).
- Capacitance of the SLC loop must not exceed 1 µF.
- 24VDC supply: Voltage drop at the end of the line under full load must not exceed 2V, or the minimum operating voltage for the last device. TPS-74A or TPS-34A power supplies can be used for remote installations or when current exceeds the panel's main supply limit.
- Accreditation: Certified to Israeli standard IS 1220.
Usage Features:
- Integrated Design: Combines detector base, horn, and/or strobe into a single unit, simplifying installation and reducing the number of devices required.
- Addressability: Each device has a unique address, allowing for precise identification and control within the fire detection system. The address of the horn/strobe horn is burned onto the device's card using PROG-4000 software or the TFC-7000 technician kit. The detector installed on the base uses its own address.
- Alarm Control: The horn and strobe light operation can be managed from the fire detection panel. The horn can be silenced, while the strobe on the TFB-180BSA will continue until a "Respond" action is initiated.
- Configurable Sound Patterns (TFB-180SA/TFB-180BA):
- Switch 1: Sets operating mode to horn/strobe or horn only.
- Switch 2: Volume adjustment (high volume (off) or low volume (on)).
- Switches 3 and 4: Control the horn sound pattern:
- Continuous sound (910Hz): Switch 3 On, Switch 4 On.
- Bell (1440 Hz): Switch 3 On, Switch 4 Off.
- Alternating sound (910Hz/600 Hz): Switch 3 Off, Switch 4 On.
- Switch 5: Stay in off state.
- TFB-180BA Specific Sound Configurations (Switches 3, 2, 1):
- 1,1,1: Constant - 910Hz
- 1,1,0: Goes up from 500Hz to 1,200Hz for 3.5 sec; stops for 0.5 seconds
- 1,0,1: Switches between 910Hz and 685Hz at a rate of 2Hz
- 1,0,0: Intermittent sound, half a second at 910Hz, half a second off
- 0,1,1: Goes down from 1,200Hz to 500Hz every second
- 0,1,0: Sounds three pulses of 500mS at 910Hz and then goes off for 1.5 seconds
- 0,0,1: Goes up and down every 0.5 second in the range of 800Hz – 1,000Hz
- 0,0,0: Goes up from 800Hz to 970Hz every second
- Indoor Installation: Designed for indoor use, requiring protection from outdoor weather conditions, high humidity, dust, and external air contamination.
Maintenance Features:
- Pre-installation Checks:
- Ensure the fire detection panel has free addresses.
- Verify wiring for short circuits, connections, or leakage to ground before connecting to the fire detection panel.
- Measure cable resistance in the field.
- Installation Procedure:
- Installation planning must comply with Israeli standard IS 1220, part 3, and planning consultant requirements.
- Connection of 24V power input and communication line (SLC) from the panel or external power source (e.g., TPS-74A or TPS-34A).
- Adding or removing assemblies from the panel must be done with all power sources (AC input voltage and batteries) disconnected.
- Notify the system manager before temporarily cutting off the fire detection panel for device additions.
- Wiring Shielding: Shielded cables are recommended for wiring outside a building to mitigate lightning strike risks. The shield must be connected to grounding clamps on the panel.
- Configuration Switches: The device includes configuration switches for setting operating mode, volume, and horn sound patterns. The switch is considered "1" when the selector is close to "1" and "0" (OPEN state) when away from "1". For TFB-180BSA, the switch is "off" when the selector is close to the digit and "on" when far away.
- Preinstallation Tests: Verify that the device is included in the relevant matrix and adheres to standard provisions and planning consultant instructions.
