AUXILIARY POWER TERMINALS

The auxiliary power supply terminals can be used to power motion detectors, keypads and other modules or accessories in the
security system. A fuseless circuit protects the power supply against current overload and automatically shuts down if the current
exceeds 1.1A. If this occurs, the Maximum Auxiliary Current failure will appear in the keypads’ Trouble Display (see page 47).
Therefore, the combined current consumption of devices connected to the auxiliary power supply should not exceed 700mA. If
the auxiliary output is overloaded and is shut down, you must disconnect all loads from the output for at least 10 seconds before
reconnecting any load back to the auxiliary output.

Modules with the APR- prefix are compatible with the Spectra 1759EX and Digiplex. Modules with the APR3- prefix are
compatible with the Spectra 1759EX, Digiplex and DigiplexNE.

TELEPHONE LINE CONNECTION

In order to report system events to the central station, you must connect the incoming telephone company wires into the TIP and
RING connections of the control panel and then run the wires from T1 and R1 to the telephone or telephone system as shown in
Figure 2.2 on page 7.

2.7

BELL OUTPUT CONNECTION

The BELL+ and BELL- terminals power bells, sirens and other warning devices requiring a steady voltage output during an alarm.
The bell output supplies 12VDC upon alarm and can support one 30-watt or two 20-watt sirens. The bell output uses a fuseless
circuit and will automatically shut down if the current exceeds 3A. When this occurs the Maximum Bell Current failure will only
appear in the keypads’ Trouble Display (see page 47) during an alarm. If the load on the BELL terminals returns to normal, the
control panel will re-instate power to the BELL terminals during the next alarm. When connecting sirens, please verify correct
polarity. Connect the positive lead to the BELL+ terminal and the negative lead to the BELL- terminal of the control panel as
shown in Figure 2.2 on page 7.

If the BELL output is not being used, the Bell Disconnected failure will remain in the keypads’ Trouble Display
(see page 47). To avoid this connect a 1K

Ω

resistor across the BELL terminals.

PROGRAMMABLE OUTPUT CONNECTIONS

When a specific event occurs in the system, a PGM can reset smoke detectors, activate strobe lights, open/close garage doors
and much more.

AND

PGM

The Spectra 1759EX control panel includes two on-board programmable outputs (PGMs). For details on how to program the
PGM, refer to PGM Programming on page 39. PGM1 can support up to 150mA while PGM2 supports up to 2.5A (see Figure 2.3
on page 9) and can be used as a strobe output (see page 40). The PGMs are limited by the power source being used. If powered
by:
• The

AUX

terminals. The current consumption of the

AUX

terminals cannot exceed 700mA. Therefore, whatever devices are con-

nected to the

AUX

terminals (i.e. modules and PGMs) cannot exceed 700mA combined. For example, if there are six modules con-

nected to the

AUX

terminals that are using 600mA and you wish to power the PGM using the

AUX

terminals, the PGM’s current

consumption will not 100mA.

• An external power supply. If using an external power supply, the current consumption cannot exceed 150mA for PGM1 and 2.5A for

PGM2. If the external power supply’s current consumption limit is less than that of the PGM it is connected to, than the current con-
sumption will not exceed the power supply’s current limit.

The Spectra 1759EX control panel also has a 5A relay. This relay can be connected as shown in Figure 2.3 on page 9. The Alarm
Relay can be programmed to follow the bell output or the activation and deactivation of the Global PGM (see Alarm Relay
Options on page 40).
