Installation TP1MAN Issue 4_03-10 (MAN0630)11 Mounting Touchpoint 1 is supplied with a mounting bracket that fits onto a suitable wall. The controller is then hooked onto the bracket. The previous diagrams show dimensions for Touchpoint 1 and the bracket. Fit the bracket to a flat, firm surface, e.g. wall, suitable for the controller’s size and weight. Recommended screw for mounting is M3.5 x 25 (or #8 x 1). 1 Mark out and drill 4 x M3 holes for the mounting bracket fixing screws. Use the mounting bracket as a template for the position of the holes. 2 Fix the bracket securely to the wall. Use appropriate fixings for the surface to which the bracket/controller is mounted. 3 With the bracket secure, locate and then lower Touchpoint 1 onto it. Ensure both top and bottom hooks on the back of the unit engage properly in the mounting bracket slots. 12.0 mm (0.5”) 228.0 mm (9.0”) 198.0 mm (7.8”) 240.0 mm (9.5”) 78.0 mm (3.0”) 100.0 mm (3.9”) Mounting Hole (6 off) Note Diagram not to scale.Thickness - 5.25 mm (0.2”) max.

Installation TP1MAN Issue 4_03-10 (MAN0630)12 Controller Components This procedure describes how to access the components inside the controller. 1 Loosen the single captive screw securing the Terminal Module access panel. The panel is located at the bottom of the enclosure. 2 Push down on the finger grips at the top of the access panel. 3 Slide the panel down to release it. 4 Pull the panel outward. Pull it until the door is approximately at a right-angle to the enclosure. 5 Push the panel inward toward the enclosure. This locks it in the open position and provides two handed access to the cable entries, etc. z 16-wire Terminal Block Fuse On/Off Switch Terminal Module Terminal Plastic Cover 3-wire Te r m i n a l B l o c k
Installation TP1MAN Issue 4_03-10 (MAN0630)13 To access the connections on the terminal blocks, slide the plastic cover fitted over them off. Ensure the plastic terminal covers are fitted once wiring is complete. 6 After carrying out the procedures subsequently described close and secure the Terminal Module Access Panel. Caution Always ensure the cover is replaced/refitted after work is complete. Power Touchpoint 1 has an auto-sensing mains power supply capable of operating between 85 and 265 Vac, 50/60 Hz. Touchpoint 1 will also accept a DC input of 19 to 32 V. Honeywell Analytics recommend that the power to the controller is sourced from a locally fused circuit. This should have an isolation facility for maintenance purposes. The table on page 17 and the terminal block diagram following it show the wiring for power to Touchpoint 1. Maximum power requirement for worst case detector and relays activated is 30 Wac and/or 15Wdc. Touchpoint 1 can accept signals from three types of detector. The table summarizes the types of detector compatible with the controller and the maximum power required. Cabling Touchpoint1 is designed for use in safe areas. Electrical installation should follow national guidelines using suitably approved cable and glands (M20 or 3/4NPT) or conduit (3/4NPT). Approved cable glands must accommodate a 360 degree termination of the EMI shield. Screened 0.5mm² (20AWG) to 2.5mm² (14AWG) cross sectional area cable should be used where appropriate to minimize unwanted effects from RF sources. 1.0mm² (16AWG) is preferred. Solid or stranded cable may be used. Ensure the cable gland is installed correctly and fully tightened. The enclosure has three knockouts in the base sized for both M20 and 3/4 in. NPT fittings. When running cabling to the unit consider conduit/cable weights to avoid any stress to the unit. The subsequent diagrams show examples of how to earth-bond Steel Wired Armored (SWA) cable at enclosures. The same principles apply to conduit installations. These bonding techniques provide good RFI/EMC performance.Type of detector Maximum Power Recommended Detector 2-wire 4-20 mA sink 500 mA (18 to 32 Vdc) Sensepoint Toxic and Oxygen 3-wire 4-20 mA source 500 mA (18 to 32 Vdc) Sensepoint Plus and Sensepoint Pro 3-wire mV bridge 2.9-3.5 Vdc, 200 mA, 0.7 W (max)Sensepoint Flammable
Installation TP1MAN Issue 4_03-10 (MAN0630)14 To calculate the maximum cable run length from the controller to the detector see page 23. Wiring Caution An earth point is provided inside the controller. Ensure that all detector screens/armor are grounded at a single earth star point at the controller or detector — BUT NOT BOTH — to prevent false alarms due to earth loops. All electrical wiring connections are made via the Terminal Module. Wire size from 0.5 to 2.5 mm 2 (20 AWG to 14 AWG). 1.0 mm2 is preferred.

Always use suitable wiring techniques and crimps when terminating cable cores, especially if
running two cores to a single terminal.
Signal and DC power connections are made via a 16-wire terminal block. Mains power is
connected via a separate 3-wire terminal block.
The diagram shows the 16-wire terminal block layout with terminal identifiers.
This table lists the terminals and their functions and specifications.
