F220-135 BOSCH

F220-135 HEAT DETECTOR -135F FIXED TEMPERATURE.

F220-135 An electronic rate-of-rise, fixed temperature heat detector that initiates an alarm when the ambient temperature exceeds +135°F (+57°C) or when the ambient temperature increases by +15°F (+8.3°C) or more in less than 1 minute

The detectors use low current electronic circuitry, so they can connect to 12 VDC nominal or 24 VDC nominal power source circuits. When mounted on the appropriate F220‑B6 Series Mounting Base, the F220 Heat Detectors provide general property protection from fire.

• Two-wire or four-wire bases
• 50 ft (15.2 m) maximum spacing between detectors
• Visible identification of model: F220‑135 = no ring, F220‑135F = gray ring, F220‑190F = black ring
• Tamper detection
• Dual color LED

F220-135 Compatible Bases

Configure the detectors as either two-wire or four-wire depending on the mounting base selected. These detectors are compatible with any of the F220‑B6 bases:
• F220‑B6 12/24 VDC Two-wire Mounting Base
• F220‑B6R Standard 12/24 VDC Four-wire Mounting Base
• F220‑B6RS 24 VDC Four-wire Mounting Base with Sounder
• F220‑B6C 12/24 VDC Four-wire Mounting Base with Auxiliary Form C Relay
• F220‑B6E 12/24 VDC Four-wire Power Supervision Mounting Base
• F220‑B6PM 24 VDC Four-wire Addressable Master Base
• F220‑B6PS 12/24 VDC Four-wire Addressable Base

F220-135 Dual-color LED

To verify the detector has power and the heat detection circuitry functions, a dual-color LED indicator flashes green every 8 sec when operating normally. It flashes once every 4 sec when a trouble condition exists. The LED latches on red if an alarm occurs, allowing the user to easily verify individual detector alarms. Clear the alarm condition by interrupting power to the detector.

F220-135 BOSCH Tamper Detection

When detector heads are correctly installed in any of the F220‑B6 bases, the control panel initiates a trouble signal if a detector is removed from its base. A mechanical tamper lock comes with each base to inhibit unauthorized head removal.

Supervision
The control panel supervises two-wire systems. Supervision of four-wire system power is provided by an end-of-line (EOL) power supervision device such as a D275 or PAM-4, or an F220‑B6E Power Supervision Mounting Base and an EOL resistor as specified by the control panel manufacturer.
