TSD012 SIGNALPOINT I/O UNIT, ISSUE 1 – 09/09/13

1. Introduction
The installation and programming of the 83-5610/MH Radio Input/Output unit used in
conjunction with the SignalPoint Control Panel, is detailed in the following instructions.
The I/O unit is a monitored input/output device, capable of transmitting VHF alarm
signals to the control panel upon activation of its hardwired input. The unit will also
receive UHF transmissions from the control panel, which remotely operates the units
relay output. An external LED is mounted on the unit for ease of checking the the units
output state. A lit LED signifies the relay is latched in an active state.
2. I/O Unit positioning
The optimum position for the I/O unit will be determined upon a radio site survey. To
ensure reliable communication it is essential that the unit is installed at the exact
location specified upon this survey. The maximum range between device and control
panel is dependant upon the environment in which the system is operating.
When selecting a site for the unit, the installing engineer should be aware that the device
should be as far away from other electrical and electronic equipment as possible. Metal
objects such as filing cabinets, pipe work, radiators and air conditioning ducts will also
adversely affect the performance of the system if they are too near the device.
3. Installation
The I/O unit is a battery-powered device therefore no power wiring is necessary. The
units input and output connection details are shown in the attached diagram Figure 1. An
installation drawing is also supplied P04242. The following paragraphs outline the
installation in a step-by-step format.
The unit should now be logged on to the system (see Input/Output Unit Logging on
Procedure section). Note: If the unit is supplied with the system, it will already be logged
onto the system.
Remove the two lid retaining screws situated on the front cover. The front section of the
unit can now be removed from the rear housing.
Offer the unit up to the wall and using the back plate as a template mark out the three
fixing holes. The unit can be fixed to the wall and all external wiring connections made.
Connections to the hardwired input has to be wired using 4k7 and 2k2 resistors in a
normally closed circuit. (See Figure 1) 4K7 is clear state, open circuit is fault and short
circuit is fault. When the 4k7 and 2k2 resistors are in series, (which makes 6K9) the I/O
unit will send an alarm signal.
The output is a standard clean contact, for switching voltage the output is rated 24v 1Ah
DC.
When all connections have been made and the unit has been logged on to the system
the lid can be re-fixed.
