Description
The Gent 34701 T Breaker Unit creates a spur from the main loop of a Vigilon or SENTRI fire alarm system, allowing S-Quad or SENTRI devices to connect on the branch. It is loop powered, with separate terminal pairs for the incoming loop, outgoing loop and spur. The round ABS enclosure measures 86 mm in diameter and 48 mm deep, has an IP40 rating and a RAL 9010 finish, and weighs 350 g. Its base has four fixing points on 50 mm centres and a central 30 mm cable entry. The terminals accept 2.5 mm² cable, and the operating temperature range is -10°C to +50°C. The spur connects at LC and 0V.
The 34701 provides a branch circuit from a Vigilon or SENTRI main loop for S-Quad or SENTRI devices. The same T Breaker is also identified by order code 78299-01NM.

The 34701 provides a branch circuit from a Vigilon or SENTRI main loop for S-Quad or SENTRI devices. The same T Breaker is also identified by order code 78299-01NM.
The incoming loop connects to L1 and 0V, the outgoing loop to L2 and 0V, and the spur to LC and 0V. The unit is loop powered. Its electrical values are Vmin 35 V, Vnom 40 V and Vmax 48 V.
The enclosure is ABS with an IP40 rating and RAL 9010 finish. It measures 86 mm across and 48 mm deep and weighs 350 g. Four base fixing points are spaced at 50 mm centres, with a central 30 mm cable entry. The terminals take 2.5 mm² conductors, and the unit operates from -10°C to +50°C.
Supplied with the mounting base and the main assembly, including the circuit board, terminal block and two fitted screws.

FAQs
What is the 34701 T Breaker used for?
The 34701 creates a spur circuit from the main loop of a Vigilon or SENTRI fire alarm system. S-Quad or SENTRI devices can connect to that branch. The unit provides separate terminal pairs for the incoming loop, outgoing loop and spur, so the branch connection is made at the T Breaker. It is loop powered and housed in a round IP40 ABS enclosure measuring 86 mm in diameter and 48 mm deep.
How do the loop and spur connections differ?
The incoming main-loop conductors connect to L1 and its 0V terminal. The outgoing main-loop conductors connect to L2 and its 0V terminal. The spur uses LC and the remaining 0V terminal, giving three separate terminal pairs. The 34701 takes its power from the loop and connects S-Quad or SENTRI devices on the spur of a Vigilon or SENTRI system. Its terminals accommodate 2.5 mm² conductors, and the enclosure has a central cable entry.
What mounting space does the 34701 need?
The circular enclosure measures 86 mm in diameter and projects 48 mm. Its base has four fixing points spaced at 50 mm centres, together with a central cable-entry hole measuring 30 mm in diameter. The main assembly has two fixing points. The complete unit weighs 350 g and uses an ABS enclosure with a RAL 9010 finish. Cable connections are made at three terminal pairs, with a terminal capacity of 2.5 mm².
What are the enclosure and operating limits?
The 34701 has an IP40 ABS enclosure finished in RAL 9010 and an operating temperature range of -10°C to +50°C. The body measures 86 mm in diameter by 48 mm deep and weighs 350 g. It connects to the fire alarm loop through 2.5 mm² terminals. Its voltage parameters are Vmin 35 V, Vnom 40 V and Vmax 48 V. Incoming, outgoing and spur wiring each have their own terminal pair.
Is 78299-01NM the same T Breaker?
The 34701 and 78299-01NM identify the same T Breaker design for creating a spur from a Vigilon or SENTRI main loop. It connects S-Quad or SENTRI devices on the branch and uses three terminal pairs for incoming loop, outgoing loop and spur wiring. The unit has an IP40 ABS enclosure in RAL 9010, measuring 86 mm across by 48 mm deep. Its terminals accept 2.5 mm² conductors, and it is powered from the loop.
