Pre-Installation Requirements

Before a STU installation can commence, a BT redcare Service Order must be

submitted to BT redcare by the Alarm Receiving Centre. This ensures that the

appropriate exchange connections have been made and a redcare block terminal

92A has been provided at the customer’s premises.

To enable an NVM to be programmed the following information is required:

a) The variant of STU is to be connected (-12V, -24V, -PLI, 11 zone or fire)

b) The alarm channels required and the function to be assigned to each

channel. The channels are typically assigned as follows:

For intruder alarm systems:

Channel 1 Fire Channel 5 Optional

Channel 2 Personal Attack Channel 6 Optional

Channel 3 Intruder Channel 7 Optional

Channel 4 Opening/Closing Channel 8 Engineer Test

For fire detection systems the fire stu has only three available channels

which can be used as required.

c) The polarity of the alarm inputs, positive applied or positive removed.

(Note: for a 3GSTU-PLI (plug-in) variant all alarm inputs must be positive

applied with the exception of alarm input 4 which must be positive

removed).

d) The type of line connection, PSTN (normal telephone line) or a Private

Wire (RedDIRECT)
