Overview

DTT Telephones

DTT telephones provide safe, reliable communications in areas that are prone to high humidity, chemical vapors, dust and physical abuse. Hands Free operation is standard on all models and the telephones can be programmed for speed dialing. All models have the option of installing a Supplemental receiver that can be held against the ear opposite to the handset, in order to improve speech recognition in noisy environments. In place of a Supplemental receiver a headset providing even greater flexibility can be installed.

Installation

• DTT telephones are shipped from the factory set for DTMF (Tone) dialing mode. If loop disconnect (Pulse) dialing is required program Register Number 52 appropriately.
• Follow all appropriate electrical codes and use only approved electrical fittings for the installation.
• If required install primary surge protection external to the telephone.
• Ensure that the telephone circuits are not live by disconnecting the Tip and
Ring conductors at the demarcation block.
• If the built in Ring Detect Relay is to be utilized to activate an external alarm ensure that the power conductors are not live.
• Using the 3mm Allen Key provided remove the four faceplate screws to detach the faceplate from the base.
• The telephone may be installed on a flat surface or wall mounted.
Desk Top Configuration
• If the telephone is to be desk top mounted set the base in the desired location.
Wall Mount Configuration
• If the telephone is to be wall mounted choose a location that is free of obstructions and permits space for wiring. Mount the base with the deepest dimension on the bottom. Mount as follows:
o The telephone weighs 3.95 kilograms (8.68 pounds), ensure that the
mounting can support four times the weight of the unit; that is 15.8 kilograms (34.8 pounds). Wall anchors are not included; follow the manufacture’s instructions when installing anchors.
o Mounting to concrete or cinder block. Lead expansion anchors with
M4 (#8) screws are recommended.
o Mounting to drywall. Hollow wall anchors (Molly Bolts) with M4 (#8)
screws are recommended.
o Mounting to other surfaces. It is the responsibility of the installer to
ensure that the base is attached in such a way as to support the weight specified above.
• Install the handset retainer clips on the faceplate using the hardware supplied.

Wiring

• WARNING: Use properly sized cable to ensure a gas/dust tight seal at the cable gland to maintain an IP66 rating, (M12 – 2 to 5mm),
(M20 – 8 to 13mm). Take care not to lose parts of the gland if the cap is
removed.
• If the telephone is wall mounted hang the faceplate on the right side of the base using two of the faceplate screws. Be careful not to lose the "O" ring retainers.
• Insert the Tip and Ring cable through the M20 gland and connect the conductors
to the Phone-Line-In terminal block.
• If an extension telephone is installed the phone line out terminals may be utilized. A four conductor cable can be used, or an additional cable can be run through the spare 20mm opening; if it is not occupied for other purposes.
• Install the supplemental receiver or headset if provided.
• If an external alerter device is utilized remove the M20 plug, install an appropriate
cable gland and connect the wiring to the Ring Detect Relay terminal block. Enable the Ring Detect Relay by inserting the jumper wire provided across the Ring Detect Relay Enable terminals.
• Tighten the cable glands securely.
• Mount the face plate and fasten the captive screws to the base.
• Connect the Tip and Ring conductors at the demarcation block.
• If the built in Ring Detect Relay is utilized apply power to the conductors.
Programming the DTT
• If necessary program the features.
Testing
• Test the unit by calling to and from another unit on the exchange.
Tip: If cable diameter is not in the range of the M12 or M20 glands provided an approved reducer and smaller gland can be fitted.

Retrofitting Headset/Supplemental Receiver, Strobe Light/Ringer

• Disconnect telephone wiring at the demarcation block and ring detect relay power at the breaker to avoid shock hazard.
• Loosen the four captive screws in the faceplate and detach the face plate from the base.
• If the telephone is wall mounted temporarily hang the faceplate to the right side of the base using two of the faceplate screws. Be careful not to lose the "O" ring retainers.
• Install the options following the instructions below.
• Tighten cable glands securely.
• Carefully replace the front plate and install all four screws.
• Reconnect telephone and ring detect relay wiring.
• Test the unit by calling to and from another unit on the exchange.
Headset / Supplemental Receiver
• If wall mounted install the Headset/Supplemental Receiver hanger to the wall 4" to 6" to the right of the telephone.
• Remove the M12 plug on the side of the face plate and install the accessory cord gland.
• Insert the cord through the gland until the sleeve protrudes 1 cm into the face plate and tighten the gland securely.
• Connect the headset wiring to the headset earpiece and microphone terminal block or if the Supplemental Receiver is utilized connect the wiring to the headset earpiece terminal block connector.
• If the headset is utilized program the phone to recognize the headset (Register Number 54).
Strobe Light /Loud Ringer
• Remove the M20 alerter device wiring plug from the base and install a cable gland.
• Insert the cord through the gland into the face plate or base and tighten the gland.
• Connect the Strobe Light or Loud Ringer wiring to the Ring Detect Relay terminal block.
• Enable the Ring Detect Relay by inserting the provided jumper wire across the Ring Detect Relay Enable terminals.
