PART 2: INSTALLATION
2.1 LOCATION AND MOUNTING
Before mounting the cabinet, push the five white nylon mounting studs into the back of the cabinet. Pull all cables into the cabinet
and prepare them for connection before mounting the circuit board into the back of the cabinet. Select a centralized installation
site on the main floor that isn't easily accessible to intruders and leave at least 5cm (2in.) around the panel box to permit
adequate ventilation and heat dissipation. The installation site should be dry and close to an AC source, ground connection and
telephone line connection. Avoid installation near or in the path of strong RF fields (i.e. neon lights, computers), on or near metal
objects, circuit breaker boxes, air conditioners and heater ducts since they may cause interference and reduce sensitivity. Avoid
installing the 1759EX in the basement.
Do not cut, bend or alter the antennae and ensure that electrical wires do not cross over the antennae as these
may affect the signal reception.
2.2 EARTH GROUND
Connect the zone and dialer ground terminals from the control panel to the metallic enclosure and cold water pipe or grounding
rod as per local electrical codes.
For maximum lightning protection, use separate earth grounds for the zone and dialer grounds as shown in
Figure 2.2 on page 4. For UL installations, the metallic enclosure must be grounded to the cold water pipe.
2.3 AC POWER
Do not use any switch-controlled outlets to power the transformer. Connect the transformer as shown in Figure 2.1 on page 3.
Use Table 1 to determine the required transformer.
2.4 BACKUP BATTERY
To provide power during a power loss, connect a 12Vdc 4Ah rechargeable acid/lead or gel cell backup battery as shown in Figure
2.1 on page 3. Use a 7Ah battery to comply with UL fire requirements. Connect the backup battery after applying AC power. When
installing, verify proper polarity as reversed connections will blow the battery fuse. Also, refer to
Battery Charge Current on page 37.

If the battery is disconnected or if the battery fuse is blown, a No/Low Battery failure will appear in the keypads’ Trouble
Display
(see page 42). This trouble will also appear if the battery’s capacity is too low or if the voltage drops to 10.5
volts or lower while the control panel is running on the backup battery. At 8.5 volts or lower, the panel shuts down and
all outputs close.
