Installation Guide
STEP 1: THE ALARM BOX
Install the back-box to the studs of the wall at the desired height. Ensure that the box is securely in place. The mounting
brackets are adjustable to suit the thickness of the wall. MAKE SURE the box is parallel, squared and flush with the
finished wall surface to ensure that the frame assembly will fit properly.
STEP 2: FOR LOCAL SENSORS ONLY
If the sensors are to be mounted locally (inside the back box), the pipe stubs must be connected to the pipeline. Using
silver-brazing techniques, connect each pipe stub to its appropriate gas or vacuum while ensuring that the bottom of
the pipe stub is wrapped with a damp cloth. BE CAREFUL not to damage the DISS check-valve by overheating the lower
portion of the copper pipe. When the brazing of pipe stubs has been completed, the system can be pressure tested.
STEP 3: STANDING PRESSURE TEST
Perform a standing pressure test on the piping system as per NFPA-99 “Health Care Facilities" or CSA-Z7396.1 "Medical Gas
Pipeline Systems". Inspect all joints for leaks and make certain each gas is piped to a correspondingly labeled gas service.
STEP 4: SENSOR
A. LOCAL (inside the back box)
i. Locate the gas-specific sensor module to be installed.
ii. In the back box, there are color coded gas labels located under the DISS Demand Check Valves. Each label
identifies where each sensor module is to be placed.
iii. The sensor module contains a gas-specific DISS fitting. Push the sensor module hex-nut
and nipple adapter up into the demand check-valve. With a wrench, tighten the nut so that
it makes a good seal.
Note:
Maximum input pressure not to exceed more than 249 psi for pressure sensors and 30 inHg for
vacuum sensors.
Alert-3 sensor operating pressure range:
Mid Pressure (0 to 99 psi) - Oxygen, Medical Air, Nitrous Oxide, Carbon Dioxide
High Pressure (0 to 249 psi) - Nitrogen, Instrument Air
Vacuum (0 to 30 inHg) - Vacuum, WAGD, AGSS
CAUTION: To protect from static electricity, ensure to discharge body static before installing the Medical Gas
alarm and sensors. Do not ground the sheild drain wire at sensor or inside alarm panel back box.
