GL-CO Gas Leak Alarm System
HML
Carbon monoxide transmitter for detecting CO concentration in air
HML and HML-N carbon monoxide transmitters are designed for measuring carbon monoxide in underground parking garages and parking halls. The measuring cell is an environmentally friendly electro-chemical cell with a long life, good long term stability, and high accuracy. As the sensor is heated, the transmitter is working also in temperatures > -30°C. The output of 0…10 V or 4…20 mA is available on the ranges of 0…100 or 0…300 ppm CO concentration for controlling ventilation.
The recommended transmitter calibration interval is one year. HMV exchange kit can be used to ensure the correct transmitter function. A new calibration report is delivered with the exchange kit.

IO-ABM Analogue Overide Module
ماژول خروجی آنالوگ
Intended for applications which require independent manual override of analogue output channels from a BMS controller, as a fail-safe in the event of controller failure. Enables actuators to be manually overridden from the panel where local access is difficult. Also useful for commissioning or temporary control of plant prior to controller installation.
- 4 x 0-10Vdc channels
- Hand/off/auto link selectable
- Manual adjustment of output signal
- 24Vac/dc powered
- Up to four outputs to be controlled from one input
- Direct or buffered output signals
LL-C-M Lighting Controller
چراغ مجهز به سنسور حرکت
The LL-C are designed to give savings over uncontrolled lighting whilst retaining an ease of installation and configuration. A passive infra-red detector monitors occupancy through moving body heat and a photo-sensitive device monitors light level. This will ensure that lighting is only switched on when the area covered is occupied and the light level is too low for normal working conditions.
MM
Liquid column manometers
The MM series liquid column manometers are engineered for HVAC/R applications. The MM series devices detect air and non-corrosive gas pressures (differential, vacuum and positive) and provide a clear analog display of the measured values.
The MM series is designed with a reservoir to protect the manometer liquid from leaking into the duct during an overpressure situation.
MM series device features include: • field adjustable zero point calibration • pressure limit stickers
The MM series device options offer: • level bubble
MM/PS
Combination of a liquid column manometer and a differential pressure switch
In many situations filter monitoring requires an alarm signal and a local display. Our filter alerts are the right solution for these situations. The filter alerts combine differential pressure switches with manometers into one practical product offering.
