T001B Relay Unit Options

HESB Wall Mounting

Some applications may require that the HESB is mounted on a wall or other vertical surface.
To wall mount the HESB
1. Find a suitable location
on the mounting
surface for the HESB
(see Figure
2. Screw a 1.25-inch
panhead wood screw
into the mounting
surface.
3. Hang the HESB from
the screw.
T001B Relay Unit Options
The T001B Unit provides a relay that can be activated by the ringing generated by a digital or
electric key telephone. The device attatched to the T001B needs to be independently powered
with a 12VDC supply (this power supply is supplied as standard with every T001B unit.) The
relay inside the T001B unit will close as soon as it detects the ringing of the extension being
called and will activate the device connected. A HHEU must also be installed in the telephone
and a HESC65 (or HESC65A) cable fitted
that can be connected to the T001B unit are as follows:
A loud ringing bell/klaxon
A flashing light
An electronic alarm/siren
Note
To install the T001B
1. Install the HHEU and HESC65 cable into the telephone.
2. Connect the other end of the HESC65 cable into the T001B unit.
3. Connect the 12V power supply to the terminal strip inside the T001B relay unit, the
positive lead to pin 3 and the negative lead to pin 1. Ensure that the power supply is set
for 12V.
4. Connect the customer supplied Bell, Flashing Lamp or Electronic Alarm to the terminal
strip inside the T001B relay unit, the positive lead pin 4 and the negative lead to pin 2.

6-15).
Care must be taken in choosing the device to be connected, as when the relay closes
having detected the ringing, the noise the chosen device generates will be constant.
This can cause some confusion with different types of alarms e.g: fire alarms. If
connecting a flashing light ensure that the device has its own integral relay to
generate the flashing, (this is usually achieved by the device using a heat sensitive
coil).
