SPECT RA SERIES 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’ Tr oubl e Di splay (see page 46) 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 al arm. When connecting sirens, please verify correct pol ari ty. Connect the positive lead to the BELL+

terminal and the negative lead to the BELL- terminal of the control panel as shown in Figure 2.1 on page 4.

If the BELL output is not being used, the Bell Disconnected failure will remain in the keypads’ Trouble

Display (see pag e 46). To avoid this connect a 1KΩ resistor across the BELL terminals.

2.8 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.

2.8.1 PGM FOR 1728EX AN D 1728

The Spectra 1728/EX control panels include one on-board programmable output (PGM).

PGM1 provides a maximum 150mA output. If the current draw on the PGM is to exceed

the current output, we r ecommend the use of a relay as shown in Figure 2- 2. For details

on how to program the PGM, refer to PGM Programming on page 37.

2.8.2 ALA RM RELAY AND PGMS FOR 1738EX AND 1738

The Spectra 1738/EX control panel includes two on-board programmable outputs

(PGMs). For details on how to program the PGM, refer to PGM Programmi ng on

page 37. PGM1 can support up to 150mA while PGM2 supports up to 2.5A (see Figure

2.4 on page 7) and can be used as a strobe output (see page 38). 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 connected to the

AUX

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

six modules connected to the

AUX

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

AUX

ter mi-

nals, the PGM’s current consumption will not 100mA.

•

An ex te rna l p ow er su ppl y.

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 1738/EX control panels also have an optional 5A relay. This relay can be connected as shown in Figure

2.4. The Alarm Relay can be programmed to follow the bell output or the activation and deactivation of the Global

PGM (see Alarm Relay Opti ons on page 38).
