Wireless Door Alarm System
Introduction
Most conventional door alarm systems have a door switch hardwired
to the alarm system requiring a lot of wires run throughout the
facility. If running wires to every door is not feasible, a wireless door
alarm system is the solution.
PTI’s wireless door alarm system has a battery-powered transmitter
installed at each door, a wireless multiplexer, and wireless receiver
connected to the multiplexer. On a typical installation transmitters
have a range of around 400 feet, however the actual range will vary
based on site conditions. On a large site, wireless repeaters should
be installed to boost the signal from the transmitters and increase
the signal range.
System Requirements
These items require a properly installed and configured control
system. The wireless multiplexer and receiver will only work
properly when installed and interfaced to the access control
system.
The firmware revision on the controller must be 4.10 or
newer for correct operation of all features.
The recommended connection to the wireless multiplexer from the
controller is through 18 AWG, 4-conductor shielded wire. This wire
must be run from the nearest device to the multiplexer.
The wireless multiplexer requires 12 VDC power at 250 mA. Power
is supplied by the power supply for the controller. Make sure the
power supply is capable of handling the necessary load when the
multiplexer is added.
The system
will not operate properly if the voltage is below 12VDC.
Extreme care should be taken when choosing a power supply
voltage and current rating. Long distance runs may require a
remote power supply to be installed in line with an RB5 relay to
ensure proper operation.
