The Fire•Lite Alarm H355 Series thermal detectors are addressable sensors that use a state-of-the-art thermistor sensing circuit for fast response. These sensors are designed to provide open-area protection and are intended for use with Fire•Lite's MS-9600 and MS-9200UD Fire Alarm Control Panels (FACPs).

Both the H355 and H355R sensors provide fixed temperature alarm detection at 135°F. The H355R sensor responds to rate-of-rise conditions of greater than 15°F/8.3°C per minute. H355HT provides fixed high-temperature detection at 190°F/88°C. These thermal detectors provide cost effective, addressable property protection in a variety of applications.

Two LEDs on each sensor light to provide a local, visible sensor indication. Remote LED annunciator capability is available as an optional accessory (P/N RA400Z).

SLC loop:
• Two-wire SLC loop connection.
• Unit uses base for wiring.
Addressing:
• Addressable by device.
• Direct Decade 01 – 159 (MS-9600), or 01 – 99 (MS-9200UD) entry of address.
Architecture:
• Sleek, low-profile, stylish design.
• State-of-the-art thermistor technology for fast response.
• Integral communications and built-in device-type identification.
• Built-in tamper resistant feature.
• Built-in functional test switch activated by external magnet.
Operation:
• Factory preset at 135°F (57°C).
• Rate-of-rise model (H355R), 15°F (8.3°C) per minute.
• 360°-field viewing angle of the visual alarm indicators (two bicolor LEDs). LEDs blink green in Normal condition and turn on steady red in Alarm.
• Visible LEDs “blink” every time the unit is addressed.
Mechanicals:
• Sealed against back pressure.
• SEMS screws for wiring of the separate base.
• Designed for direct-surface or electrical-box mounting.
• Plugs into separate base for ease of installation and maintenance.
• Separate base allows interchange of photoelectric, ionization and thermal sensors.
Other system features:
• Remote test feature from the panel.
• Walk test with address display.
• Low standby current.
• 94-5V plastic flammability rating.
Options:
• Remote LED output connection to optional RA400Z remote LED annunciator.
• Recessed (RMK400) or surface (SMK400) base mounting kits.
