2. Installation
Usage other than approved usage or failure to comply with the instructions
may invalidate any approval given to the apparatus, if, as a result, the
apparatus ceases to comply with the standards against which approval was
granted.
Digital Communicator Outputs
("6" in Figure 2.)
The control unit provides 8 programmable outputs, which could be used to
operate a digital communicator – a device that transmits the status of each
channel to an Alarm Receiving Centre (where each channel could represent a
zone alarm status). Alternatively, low-power devices such as LEDs could be
switched on or off by these outputs (see Figure 9).
By default, each output is switched negative, i.e. normally at +12Vdc and
switches to 0V when active. When at 0V, up to 100mA can flow into the output
from an external source.
If required, the sense can be reversed during system configuration, i.e.
normally at +0V and switches to 12Vdc when active. In this case, when
switching to +12Vdc, each output can deliver up to 5mA to an external load.
The terminal block labelled "16" in Figure 2 can provide a +12Vdc supply to a
digital communicator.
Transistor Outputs
("7" in Figure 2.)
The programmable transistor outputs provide control for external equipment
such as LEDs, buzzers and relays. The following outputs are provided:
• One switched-negative output (-2). This can switch from 12Vdc to 0V on
activation, and is able sink up to 500mA from a 12Vdc source. See Figure
9 for examples.
• One switched-positive output (+3). This switches from 0V to 12Vdc on
activation, and can deliver up to 500mA to an external load. See Figure 10
for examples.
Each output can be programmed to activate when, for example:
• There is an alarm in a specified zone.
• There is a panic alarm.
• Mains is disconnected from the control unit.
• A specified user passcode is entered.
• A combination of specified conditions occur.
The 95/65 Engineering Manual provides full details of output programming.
