Description

Honeywell /355, H/355R, H/355HT Series - Thermal Detector

General

The Fire•Lite Alarms H/355 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 the Fire•Lite’s addresable Fire Alarm Control Panels (FACPs).

The H/355 and H/355R sensors provide fixed temperature alarm detection at 135°F (57°C). The H/355R sensor also responds to rate-of-rise conditions of greater than 15°F (8.3°C) per minute. The H/355HT is a fixed high-temperature detector that activates 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).

Features

SLC loop

- Two-wire SLC loop connection.
- Unit uses base for wiring.

Addressing

- Add ressable by device.
- Direct Decade entry of address: 01 – 159 with MS-9600, 01 – 99 with MS-9200UD.

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) for the H/355  and H/355R; 190°F (88°C) for the H355HT
- Rate-of-rise triggers at 15°F (8.3°C) per minute for the H/355R.
- 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.

H/355 with B501 base

- 94- 5V plastic flammability rating.

Options

- Remote LED output connection to optional RA/400Z remote LED annunciator.
- Recessed (RMK/400) or surface (SMK/400E ) base mounting kits.

Installation

H355 Series plug-in intelligent thermal detectors use a detachable base to simplify installation, service and maintenance. Installation instructions are shipped with each detector.

Mount base (all base types) on box that is at least 1.5" (3.81 cm) deep. Suitable boxes include:

    4 .0" (10.16 cm) square box with mud ring.
    3 . 5. " (8.89 cm) octagonal box.

NOTE: Because of the inherent supervision provided by the SLC loop, end-of-line resistors are not required. Wiring “T-taps” or branches are permitted for Style 4 (Class “B”) wiring only.

Applications

Use thermal detectors for protection of property.

Construction

These detectors are constructed of off-white Bayblend®. The H355 Series plug-in intelligent thermal detectors are designed to commercial standards and offer an attractive appearance.

Operation

Each H/355 Series detector uses one of 159 (MS-9600) or 99 (MS-9200UD)  possible addresses on a control panel SLC loop. It responds to regular polls from the control panel and reports its type and the status. If it receives a test command from the panel (or a local magnet test), it stimulates its electronics and reports an alarm. It blinks its LEDs when polled and turns the LEDs on when commanded by the panel. The H/355 Series offers features and performance that represent the latest in thermal detector technology.
