4.2 Normally closed door with pre-warning (see drawing 001/7)
A magnetic door contact can be fitted. If a patient wearing a wristband enters the detection zone, the
local sounder is activated (pre-alarm warning) and if fitted the door lock energized (refer to J11 option).
While the door remains closed, the door monitor does not activate any main alarm.
Should the door be opened (following the pre-selected lock/s applied time), an alarm will immediately be
activated and transmitted to a central monitor, or other display and indication device to be indicated as a
full alarm.
Upon receiving the pre-warning, the patient should retreat from the sensor detection zone. After a short
period the door lock will be released (unless set to always be “on” i.e. time setting zero (“0”)). If the door
is now opened no alarm is activated provided the patient is no longer within range.
4.3 Full alarm reset/bypass
A full alarm at the door monitor can be reset by a caregiver using either the remote wireless reset
transmitter, magnetic proximity key etc. This reset transmitter may also be used to “bypass” the door
alarm for a preset period of time to allow a patient wearing a wristband to be escorted through a protected
door. Other devices may be employed to reset/bypass the door alarm (refer to “Reset” terminal on
connector shown in drawing 001/1 and 001/3).
4.4 Functionality
The door monitor unit incorporates a wireless “data” receiver that detects and reads the identity of each
transmitter. It can simultaneously receive a number of transmitters passing through the detection field.
Separate field strength receivers are built into the monitor unit to detect and analyze the strength of
signals emitted from nearby wristband transmitters and therefore the approximate distance from the
doorway.
4.5 Patient transmitter programming and battery saving
As standard procedure, patient wristbands are supplied pre-programmed with factory standard ID
numbers and with the transmitter de-activated (switched off) to conserve the battery.
A simple procedure for activation (switch on) of a “dormant” wristband transmitter is described in section
3.3.1 above and in drawing 001/4.
Programming information describing how to set individual ID numbers and/or de-activate (switch off) the
wristband transmitter is provided in the Rondish Transmitter Programming Instruction Manual.
