5.10.3. Elevator Receive (RX) Antenna
Locate a suitable position for the RX Antenna. Should the elevator have a dropped ceiling which is
accessible, this area may be used for the antenna provided that the insulation between the antenna and the
cab is not treated with a foil backing. Should such a foil backing be present, you may strip the foil from the
fiberglass and discard it. Do not locate the RX Antenna above a metal or metalized plastic egg-crate
ceiling, as this would render it ineffective.
It is recommended that the RX Antenna be mounted in the horizontal plane, parallel to the elevator floor, to
reduce noise pick-up.
• Place the RX Antenna on the surface to which it will be placed and mark the point through which
the coax cable will exit.
• Drill a suitable hole at the location marked and place a grommet into this hole to protect the coax
cable from getting frayed.
• Clean the surface where the antenna is to be mounted with alcohol or similar cleanser. Remove the
protective strip from the double-sided tape at the back of the RX Antenna and mount the antenna
to this surface.
• Thread the coax cable through the grommet and connect it to the Controller within the HALO
Elevator Cabinet.
5.10.4. Audible Alarm Module
The Audible Alarm module can be mounted on the elevator “COP” panel. If the elevator car has an egg-
crate style ceiling, a dropped ceiling or a lighting valance, the Audible Alarm module may be mounted in
this location as well. An open area should be chosen so as to allow the alarm sounds to be clearly heard.
The switch on the module is to select between “Exciter Field Test Mode” and “Normal Operation”. With
“Exciter Field Test Mode” selected, the beeper on the module will sound momentarily each time a valid
response is received from a Transponder. This helps to determine the outside limits of the detection field,
and whether any null areas exist within this field.
• Identify the location where the Audible Alarm Module will be located, ensuring that easy access can
be gained for the 6-conductor cable that connects it to the Elevator Cabinet.
• Secure the Audible Alarm Module with the metal self-tapping screws provided, to the elevator car
ceiling or the wall above a suspended ceiling, or the “COP” panel.
• Connect one end of the Audible Alarm Cable to the module and the other end to the connector marked
“P4” on the Elevator Interface Module (EIM) within the cabinet.
5.10.5. Keypad
It is recommended that the Keypad be mounted on the elevator “COP” panel at a height that allows easy
access for the nursing staff who must enter a 3-7 digit code to enable the Bypass mode. If there is no spare
space available on the “COP” panel, the Keypad may be mounted in a suitable location on the elevator
wall.
• Cut a hole in the “COP” panel to accommodate the rear of the Keypad assembly that will be inserted.
• Drill holes for the screws, using the Keypad as a template to locate the correct positions for these
holes.
• Thread the Keypad Cable supplied through the “COP” panel and up to the cabinet.
• Plug one end of the cable to the Keypad and the other end to the EIM within the cabinet.
